Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction of Notes to Condensed Consolidated Financial Statements	The Condensed Consolidated Financial Statements at September 30, 2015 and for the quarters and nine months ended September 30, 2015 and 2014 are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the results for the interim periods. The results reported in these Condensed Consolidated Financial Statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the financial statements and notes in our Annual Report to Shareowners ( 2014 Annual Report) incorporated by reference to our Annual Report on Form 10-K for calendar year 2014 ( 2014 Form 10-K). Certain reclassifications have been made to the prior year amounts to conform to the current year presentation. On July 20, 2015, we announced an agreement to sell our Sikorsky Aircraft (Sikorsky) business to Lockheed Martin Corp. for $9 billion in cash, subject to a working capital and net indebtedness adjustment. As a result, Sikorsky met "held for sale" criteria in the quarter ended September 30, 2015 . Sikorsky's results of operations and the related cash flows which result from this business have been reclassified to Discontinued Operations in our Condensed Consolidated Statement of Operations and Condensed Consolidated Statement of Cash Flows for all periods presented. The assets and liabilities of Sikorsky have been reclassified to Assets held for sale and Liabilities held for sale, respectively, in our Condensed Consolidated Balance Sheet as of September 30, 2015 and December 31, 2014. The sale is expected to close during the fourth quarter of 2015, subject to customary closing conditions, including regulatory approval. See Note 2 to the Condensed Consolidated Financial Statements for further discussion.

Business Combination, Recognized Identifiable Assets Acquired, Goodwill, and Liabilities Assumed, Net [Abstract]
Acquisitions, Dispositions, Goodwill and Other Intangible Assets [Text Block]	Acquisitions, Dispositions, Goodwill and Other Intangible Assets Business Acquisitions and Dispositions. During the nine months ended September 30, 2015 , our investment in business acquisitions was $347 million , including debt assumed of $18 million , and consisted of the acquisition of the majority interest in a UTC Climate, Controls & Security business and a number of small acquisitions, primarily in our commercial businesses. As a result of the 2012 transactions related to IAE International Aero Engines AG (IAE), Pratt & Whitney holds a 61% net interest in the collaboration and a 49.5% ownership interest in IAE. IAE's business purpose is to coordinate the design, development, manufacturing and product support of the V2500 jet engine program through involvement with the collaborators. IAE retains limited equity with the primary economics of the V2500 program passed to the participants in the separate collaboration arrangement. As such, we have determined that IAE is a variable interest entity with Pratt & Whitney its primary beneficiary, and IAE has, therefore, been consolidated. The carrying amounts and classification of assets and liabilities for IAE in our Condensed Consolidated Balance Sheet as of September 30, 2015 are as follows: (Dollars in millions) Current assets $ 1,719 Noncurrent assets 1,073 Total assets $ 2,792 Current liabilities $ 1,738 Noncurrent liabilities 1,457 Total liabilities $ 3,195 Goodwill. Changes in our goodwill balances for the nine months ended September 30, 2015 were as follows: (Dollars in millions) Balance as of Goodwill Resulting from Business Combinations Foreign Currency Translation and Other Balance as of Otis $ 1,664 $ 6 $ (121 ) $ 1,549 UTC Climate, Controls & Security 9,408 386 (267 ) 9,527 Pratt & Whitney 1,481 36 — 1,517 UTC Aerospace Systems 14,892 — (135 ) 14,757 Total Segments 27,445 428 (523 ) 27,350 Eliminations and other 3 1 — 4 Total $ 27,448 $ 429 $ (523 ) $ 27,354 Intangible Assets.

We amortize these intangible assets based on the underlying pattern of economic benefit, which may result in an amortization method other than straight-line. We classify amortization of such payments as a reduction of sales. The IAE collaboration intangible asset is amortized based upon the pattern of economic benefits as represented by the underlying cash flows. Amortization of intangible assets for the quarter and nine months ended September 30, 2015 was $183 million and $537 million , respectively, compared with $182 million and $536 million for the same periods of 2014. The following is the expected amortization of intangible assets for the years 2015 through 2020 , which reflects an increase in expected amortization expense due to the pattern of economic benefit on certain aerospace intangible assets. (Dollars in millions) Remaining 2015 2016 2017 2018 2019 2020 Amortization expense $ 176 $ 709 $ 747 $ 775 $ 769 $ 783

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations On July 20, 2015 , we announced an agreement to sell our Sikorsky business to Lockheed Martin Corp. for $9 billion in cash, subject to a working capital and net indebtedness adjustment. The sale is expected to close during the fourth quarter of 2015, and is subject to customary closing conditions, including regulatory approval. The sale is expected to generate approximately $6 billion in net cash, on an after-tax basis. In the quarter ended September 30, 2015 , Sikorsky met "held for sale" criteria. Sikorsky's results of operations and the related cash flows which result from this business have been reclassified to Discontinued Operations in our Condensed Consolidated Statement of Operations and Condensed Consolidated Statement of Cash Flows for all periods presented. The assets and liabilities of Sikorsky have been reclassified to Assets held for sale and Liabilities held for sale, respectively, in our Condensed Consolidated Balance Sheet as of September 30, 2015 and December 31, 2014. Cash flows from the operation of Sikorsky will continue to be included in our results until completion of the sale to Lockheed Martin Corp.

The need for commercial paper borrowings arises when the use of domestic cash for acquisitions, dividends, and share repurchases exceeds the sum of domestic cash generation and foreign cash repatriated to the U.S. Long-term debt consisted of the following: (Dollars in millions) September 30, 2015 December 31, 2014 LIBOR plus 0.500% floating rate notes due 2015 $ — $ 500 4.875% notes due 2015 — 1,200 5.375% notes due 2017 1 1,000 1,000 1.800% notes due 2017 1 1,500 1,500 1.778% junior subordinated notes due 2018 1,100 — 6.800% notes due 2018 4 99 99 6.125% notes due 2019 1 1,250 1,250 8.875% notes due 2019 271 271 4.500% notes due 2020 1 1,250 1,250 4.875% notes due 2020 4 171 171 8.750% notes due 2021 250 250 3.100% notes due 2022 1 2,300 2,300 1.550% junior subordinated notes due 2022 — 1,100 1.250% notes due 2023 (€750 million principal value) 2 837 — 7.100% notes due 2027 4 141 141 6.700% notes due 2028 400 400 7.500% notes due 2029 1 550 550 5.400% notes due 2035 1 600 600 6.050% notes due 2036 1 600 600 6.800% notes due 2036 4 134 134 7.000% notes due 2038 4 159 159 6.125% notes due 2038 1 1,000 1,000 5.700% notes due 2040 1 1,000 1,000 4.500% notes due 2042 1 3,500 3,500 4.150% notes due 2045 3 850 — Project financing obligations 210 147 Other (including capitalized leases) 4 319 368 Total principal long-term debt 19,491 19,490 Other (fair market value adjustments and discounts) 4 152 168 Total long-term debt 19,643 19,658 Less: current portion 215 1,791 Long-term debt, net of current portion $ 19,428 $ 17,867 1 We may redeem the above notes, in whole or in part, at our option at any time at a redemption price in U.S. Dollars equal to the greater of 100% of the principal amount of the notes to be redeemed or the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted to the redemption date on a semiannual basis at the adjusted treasury rate plus 10-50 basis points. The redemption price will also include interest accrued to the date of redemption on the principal balance of the notes being redeemed. 2 We may redeem these notes, in whole or in part, at our option at any time. If redeemed prior to February 22, 2023, the redemption price in Euro shall equal the greater of 100% of the principal amount of the notes to be redeemed or the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted to the redemption date on an annual basis at a rate based upon a comparable German federal government bond whose maturity is closest to the maturity of the notes plus 15 basis points. In addition, the notes may be redeemed at our option in whole, but not in part, at any time in the event of certain developments affecting U.S. taxation. 3 We may redeem these notes, in whole or in part, at our option at any time. If redeemed prior to November 16, 2044, the redemption price in U.S. Dollars shall equal the greater of 100% of the principal amount of the notes to be redeemed or the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted to the redemption date on a semiannual basis at the adjusted treasury rate plus 25 basis points. 4 Includes notes and remaining fair market value adjustments that were assumed as a part of the Goodrich acquisition on July 26, 2012. On May 4, 2015, we completed the previously announced optional remarketing of the 1.550% junior subordinated notes, which were originally issued as part of our equity units on June 18, 2012. As a result of the remarketing, these notes were redesignated as our 1.778% junior subordinated notes due May 4, 2018. The 1.778% junior subordinated notes are effectively subordinated to existing or future preferred stock and indebtedness, guarantees and other liabilities, and are not redeemable prior to maturity. On August 3, 2015, we received approximately $1.1 billion from the proceeds of the remarketing, and issued approximately 11.3 million shares of Common Stock to settle the purchase obligation of the holders of the equity units under the purchase contract entered into at the time of the original issuance of the equity units. On May 1, 2015 , we repaid all 4.875% notes due in 2015, representing $1.2 billion in aggregate principal. On June 1, 2015 , we repaid all floating rate notes due in 2015, representing $500 million in aggregate principal. On May 4, 2015 , we issued $850 million aggregate principal amount of 4.150% notes due May 15, 2045. On May 22, 2015 we issued €750 million aggregate principal amount of 1.250% notes due May 22, 2023. The net proceeds from these debt issuances were used primarily to repay the notes that matured during the quarter ended June 30, 2015. We have an existing universal shelf registration statement filed with the Securities and Exchange Commission (SEC) for an indeterminate amount of equity and debt securities for future issuance, subject to our internal limitations on the amount of equity and debt to be issued under this shelf registration statement.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We conduct business globally and, as a result, UTC or one or more of our subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Belgium, Canada, China, France, Germany, Hong Kong, Italy, Japan, Singapore, South Korea, Spain, the United Kingdom and the United States. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2003. In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. It is reasonably possible that a net reduction within a range of $25 million to $540 million of unrecognized tax benefits may occur within the next twelve months as a result of additional worldwide uncertain tax positions, the revaluation of current uncertain tax positions arising from developments in examinations, in appeals, or in the courts, or the closure of tax statutes. See Note 14, Contingent Liabilities, for discussion regarding uncertain tax positions, included in the above range, related to pending litigation with respect to certain deductions claimed in Germany. UTC tax years 2011 and 2012 are currently under review by the Examination Division of the Internal Revenue Service (IRS), which is expected to continue beyond the next 12 months. Goodrich Corporation tax years 2011 and 2012 through the date of acquisition by UTC are currently under review by the Examination Division of the IRS, which is also expected to continue beyond the next 12 months.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments [Text Block]	Financial Instruments We enter into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments under the Derivatives and Hedging Topic of the FASB ASC and those utilized as economic hedges. We operate internationally and, in the normal course of business, are exposed to fluctuations in interest rates, foreign exchange rates and commodity prices. These fluctuations can increase the costs of financing, investing and operating the business. We have used derivative instruments, including swaps, forward contracts and options to manage certain foreign currency, interest rate and commodity price exposures. The four quarter rolling average of the notional amount of foreign exchange contracts hedging foreign currency transactions was $15.4 billion and $13.9 billion at September 30, 2015 and December 31, 2014 , respectively. The following table summarizes the fair value of derivative instruments as of September 30, 2015 and December 31, 2014 which consist solely of foreign exchange contracts: Asset Derivatives Liability Derivatives (Dollars in millions) September 30, 2015 December 31, 2014 September 30, 2015 December 31, 2014 Derivatives designated as hedging instruments $ 7 $ 3 $ 377 $ 248 Derivatives not designated as hedging instruments 119 139 73 71 As discussed in Note 5, on May 22, 2015 we issued approximately €750 million of Euro-denominated debt, which qualifies as a net investment hedge against our investments in European businesses under ASC 815, Derivatives and Hedging. As of September 30, 2015 , the net investment hedge is deemed to be effective as defined under ASC 815. The amount of gains and losses related to the Company's derivative financial instruments was as follows: Quarter Ended September 30, Nine Months Ended September 30, (Dollars in millions) 2015 2014 2015 2014 Loss recorded in Accumulated other comprehensive loss $ (152 ) $ (142 ) $ (274 ) $ (120 ) Loss reclassified from Accumulated other comprehensive loss into Product sales (effective portion) 64 24 164 55 Assuming current market conditions continue, a $211 million pre-tax loss is expected to be reclassified from Accumulated other comprehensive loss into Product sales to reflect the fixed prices obtained from foreign exchange hedging within the next 12 months. At September 30, 2015 , all derivative contracts accounted for as cash flow hedges will mature by October 2017. The effect on the Condensed Consolidated Statement of Operations of foreign exchange contracts not designated as hedging instruments was as follows: Quarter Ended September 30, Nine Months Ended September 30, (Dollars in millions) 2015 2014 2015 2014 Gain recognized in Other income, net $ 35 $ 10 $ 65 $ 22 We received $147 million and $153 million from settlements of derivative contracts during the nine months ended September 30, 2015 and 2014, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements The Fair Value Measurements and Disclosure Topic of the FASB ASC establishes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. A financial asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1 - quoted prices in active markets for identical assets or liabilities; • Level 2 - inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly; and • Level 3 - unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. The following tables provide the valuation hierarchy classification of assets and liabilities that are carried at fair value and measured on a recurring and nonrecurring basis in our Condensed Consolidated Balance Sheet as of September 30, 2015 and December 31, 2014 : September 30, 2015 (Dollars in millions) Total Level 1 Level 2 Level 3 Recurring fair value measurements: Available-for-sale securities $ 849 $ 849 $ — $ — Derivative assets 126 — 126 — Derivative liabilities (450 ) (1 ) (449 ) — December 31, 2014 (Dollars in millions) Total Level 1 Level 2 Level 3 Recurring fair value measurements: Available-for-sale securities $ 961 $ 961 $ — $ — Derivative assets 142 — 142 — Derivative liabilities (319 ) — (319 ) — Nonrecurring fair value measurements: Business dispositions 3 — 3 — We have recorded net gains of approximately $126 million during the nine months ended September 30, 2015 , as a result of a fair value adjustment related to the acquisition of a controlling interest in a UTC Climate, Controls & Security joint venture investment. We recorded net gains of approximately $23 million , including a $48 million net gain during the nine months ended September 30, 2014 , as a result of fair value adjustments related to the acquisitions of the majority interest in a Pratt & Whitney joint venture. During the nine months ended September 30, 2014 , we also recorded a net gain of approximately $30 million from UTC Climate, Controls & Security's ongoing portfolio transformation, primarily due to a gain on the sale of an interest in a joint venture in North America, and a charge of approximately $28 million , included in discontinued operations, to adjust the fair value of a Sikorsky joint venture investment. Valuation Techniques. Our available-for-sale securities include equity investments that are traded in active markets, either domestically or internationally, and are measured at fair value using closing stock prices from active markets. Our derivative assets and liabilities include foreign exchange contracts and commodity derivatives that are measured at fair value using internal models based on observable market inputs such as forward rates, interest rates, our own credit risk and our counterparties' credit risks. As of September 30, 2015 , there were no significant transfers in and out of Level 1 and Level 2. As of September 30, 2015 , there has not been any significant impact to the fair value of our derivative liabilities due to our own credit risk. Similarly, there has not been any significant adverse impact to our derivative assets based on our evaluation of our counterparties' credit risks. The following table provides carrying amounts and fair values of financial instruments that are not carried at fair value in our Condensed Consolidated Balance Sheet at September 30, 2015 and December 31, 2014 : September 30, 2015 December 31, 2014 (Dollars in millions) Carrying Amount Fair Value Carrying Amount Fair Value Long-term receivables $ 126 $ 110 $ 214 $ 204 Customer financing notes receivable 370 369 262 260 Short-term borrowings (3,024 ) (3,024 ) (126 ) (126 ) Long-term debt (excluding capitalized leases) (19,617 ) (21,265 ) (19,623 ) (22,244 ) Long-term liabilities (280 ) (298 ) (80 ) (74 ) The following table provides the valuation hierarchy classification of assets and liabilities that are not carried at fair value in our Condensed Consolidated Balance Sheet as of September 30, 2015 : (Dollars in millions) Total Level 1 Level 2 Level 3 Long-term receivables $ 110 $ — $ 110 $ — Customer financing notes receivable 369 — 369 — Short-term borrowings (3,024 ) — (2,877 ) (147 ) Long-term debt (excluding capitalized leases) (21,265 ) — (20,886 ) (379 ) Long-term liabilities (298 ) — (298 ) — We had commercial aerospace financing and other contractual commitments totaling approximately $10.3 billion and $11.3 billion as of September 30, 2015 and December 31, 2014 , respectively, related to commercial aircraft and certain contractual rights to provide product on new aircraft platforms. Risks associated with changes in interest rates on these commitments are mitigated by the fact that interest rates are variable during the commitment term, and are set at the date of funding based on current market conditions, the fair value of the underlying collateral and the credit worthiness of the customers. As a result, the fair value of these financings is expected to equal the amounts funded. The fair value of these commitments is not readily determinable.

Receivables [Abstract]
Long-Term Financing Receivables [Text Block]	Long-Term Financing Receivables Our long-term financing receivables primarily represent balances related to our aerospace businesses, such as long-term trade accounts receivable, leases receivable, and notes receivable. We also have other long-term receivables related to our commercial businesses; however, both the individual and aggregate amounts of those other receivables are not significant. Long-term trade accounts receivable, including unbilled receivables primarily related to long-term aftermarket contracts, are principally amounts arising from the sale of goods and delivery of services with a contractual maturity date or realization period of greater than one year, and are recognized as Other assets in our Condensed Consolidated Balance Sheet. Notes and leases receivable represent notes and lease receivables other than receivables related to operating leases, and are recognized as Customer financing assets in our Condensed Consolidated Balance Sheet. The following table summarizes the balance by class of aerospace business-related long-term receivables as of September 30, 2015 and December 31, 2014 . (Dollars in millions) September 30, 2015 December 31, 2014 Long-term trade accounts receivable $ 794 $ 651 Notes and leases receivable 460 381 Total long-term receivables $ 1,254 $ 1,032 Customer credit ratings range from customers with an extremely strong capacity to meet financial obligations, to customers whose uncollateralized receivable is in default. There can be no assurance that actual results will not differ from estimates or that consideration of these factors in the future will not result in an increase or decrease to the allowance for credit losses on long-term receivables. Based upon the customer credit ratings, approximately 12% and 9% of our total long-term receivables were considered to bear high credit risk as of September 30, 2015 and December 31, 2014 , respectively. For long-term trade accounts receivable, we evaluate credit risk and collectability individually to determine if an allowance is necessary. Our long-term receivables included in the table above are individually evaluated for recoverability, and we had valuation reserves of $19 million as of September 30, 2015 and $10 million as of December 31, 2014 . At September 30, 2015 and December 31, 2014 , we did not have any significant balances that are considered to be delinquent, on non-accrual status, past due 90 days or more, or considered to be not recoverable.

LLC to repurchase shares of our common stock for an aggregate purchase price of $2.65 billion . Each ASR agreement provided for the repurchase of our common stock based on the average of the daily volume-weighted average prices of our common stock during the term of such ASR agreement, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR agreement. On March 13, 2015, we paid the aggregate purchase price and received an initial delivery of 18.6 million shares of common stock at a price of $121.24 per share, representing approximately 85% of the shares expected to be repurchased. The aggregate purchase price was recorded as a reduction to Shareowners’ Equity, consisting of a $2.25 billion increase in Treasury Stock and a $398 million decrease in additional paid-in capital. On July 31, 2015, the shares associated with the remaining portion of the aggregate purchase were settled upon final delivery of approximately 4.2 million additional shares of common stock. Including the remaining shares settled on July 31, 2015, the final price under the ASR was $116.11 per share. The $398 million initially recorded in additional paid-in capital was reclassified to Treasury Stock. As discussed in Note 5, on August 3, 2015, we received approximately $1.1 billion from the proceeds of the remarketing of our 1.550% junior subordinated notes, which were originally issued as part of our equity units on June 18, 2012, and issued approximately 11.3 million shares of common stock to settle the purchase obligation of the holders of the equity units under the purchase contract entered into at the time of the original issuance of the equity units.

These costs are recorded as components of net periodic pension cost for each period presented (see Note 7 for additional details). All noncontrolling interests with redemption features, such as put options, that are not solely within our control (redeemable noncontrolling interests) are reported in the mezzanine section of the Condensed Consolidated Balance Sheet, between liabilities and equity, at the greater of redemption value or initial carrying value.

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities [Text Block]	Contingent Liabilities Summarized below are the matters previously described in Note 17 of the Notes to the Consolidated Financial Statements in our 2014 Annual Report, incorporated by reference in our 2014 Form 10-K, updated as applicable. Except as otherwise noted, while we are unable to predict the final outcome, based on information currently available, we do not believe that resolution of any of the following matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition. Environmental. Our operations are subject to environmental regulation by federal, state and local authorities in the United States and regulatory authorities with jurisdiction over our foreign operations. As described in Note 1 to the Consolidated Financial Statements in our 2014 Annual Report, we have accrued for the costs of environmental remediation activities and periodically reassess these amounts. We believe that the likelihood of incurring losses materially in excess of amounts accrued is remote. Additional information pertaining to environmental matters is included in Note 1 to the Consolidated Financial Statements in our 2014 Annual Report. Government. We are now, and believe that, in light of the current U.S. Government contracting environment, we will continue to be the subject of one or more U.S. Government investigations. If we or one of our business units were charged with wrongdoing as a result of any of these investigations or other government investigations (including violations of certain environmental or export laws) the U.S. Government could suspend us from bidding on or receiving awards of new U.S. Government contracts pending the completion of legal proceedings. If convicted or found liable, the U.S. Government could fine and debar us from new U.S. Government contracting for a period generally not to exceed three years. The U.S. Government could void any contracts found to be tainted by fraud. Our contracts with the U.S. Government are also subject to audits. Like many defense contractors, we have received audit reports which recommend that certain contract prices should be reduced to comply with various government regulations. Some of these audit reports involved substantial amounts. We have made voluntary refunds in those cases we believe appropriate, have settled some allegations and continue to litigate certain cases. In addition, we accrue for liabilities associated with those matters that are probable and can be reasonably estimated. The most likely settlement amount to be incurred is accrued based upon a range of estimates. Where no amount within a range of estimates is more likely, then we accrued the minimum amount. Legal Proceedings. F100 Engine Litigation As previously disclosed, the United States Government sued us in 1999 in the United States District Court for the Southern District of Ohio, claiming that Pratt & Whitney violated the civil False Claims Act and common law. The claims relate to the “Fighter Engine Competition” between Pratt & Whitney's F100 engine and General Electric's F110 engine. The government alleged that it overpaid for F100 engines under contracts awarded by the U.S. Air Force in fiscal years 1985 through 1990 because Pratt & Whitney inflated its estimated costs for some purchased parts and withheld data that would have revealed the overstatements. At trial, which ended in April 2005, the government claimed Pratt & Whitney's liability to be approximately $624 million. On August 1, 2008, the trial court held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions after the alleged overstatements were made. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in its 1983 initial engine pricing proposal. In the absence of actual damages, the trial court awarded the government the maximum civil penalty of $7,090,000, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts. In September 2008, both the government and UTC appealed the decision to the United States Court of Appeals for the Sixth Circuit. In November 2010, the Sixth Circuit affirmed Pratt & Whitney's liability for the civil penalty under the False Claims Act, but remanded the case to the trial court for further proceedings on the issues of False Claims Act damages and common law liability and damages. On June 18, 2012, the trial court found that Pratt & Whitney had breached obligations imposed by common law based on the same conduct with respect to which the court previously found liability under the False Claims Act. Under the common law claims, the U.S. Air Force seeks damages for events occurring before March 3, 1989, which are not recoverable under the False Claims Act. On June 17, 2013, the trial court awarded the government approximately $473 million in damages and penalties, plus prejudgment interest in an amount to be determined. On July 1, 2013, the trial court, after determining the amount of prejudgment interest, entered judgment in favor of the government in the amount of approximately $664 million. The trial court also awarded post-judgment interest on the full amount of the judgment to accrue from July 2, 2013, at the federal variable interest rate determined pursuant to 28 U.S.C. § 1961. The judgment included four different components: (1) common law damages of approximately $109 million; (2) prejudgment interest on common law damages of approximately $191 million; (3) False Claims Act treble damages of approximately $357 million; and (4) the civil penalty of approximately $7 million. The penalty component of the judgment previously was affirmed by the United States Court of Appeals in 2010. We filed an appeal from the judgment to the United States Court of Appeals for the Sixth Circuit on August 26, 2013. On April 6, 2015, the Sixth Circuit reversed the trial court’s decision and vacated the prior damages award, noting that the government did not prove any damages. The court rejected as a matter of law the evidence submitted by the government on damages and remanded the case to the trial court to decide in the first instance whether the government should have another opportunity to prove that it suffered any actual damages. On July 17, 2015, the case returned to the District Court, at which time we filed a motion for entry of judgment, seeking a judgment of zero actual damages. The government responded by filing a motion on August 28, 2015, in which it abandoned its claim for actual damages, but now seeks a judgment of approximately $85 million, representing (1) disgorgement of UTC’s alleged profits in fiscal year 1985, the first year of the multi-year engine competition, (2) prejudgment interest and (3) the civil penalty. We continue to believe that the government suffered no actual damages as a result of the inaccurate statements made in 1983. We also believe that there is no basis for the government’s new profit disgorgement claim. Accordingly, we continue not to accrue a reserve beyond the approximately $7 million civil penalty referenced above. Cost Accounting Standards Claim By letter dated December 24, 2013, a Divisional Administrative Contracting Officer of the United States Defense Contract Management Agency asserted a claim and demand for payment of approximately $211 million against Pratt & Whitney. The claim is based on Pratt & Whitney's alleged noncompliance with cost accounting standards from January 1, 2005 to December 31, 2012, due to its method of determining the cost of collaborator parts used in the calculation of material overhead costs for government contracts. We believe this claim is without merit. On March 18, 2014, Pratt & Whitney filed an appeal to the Armed Services Board of Contract Appeals. German Tax Litigation As previously disclosed, UTC has been involved in administrative review proceedings with the German Tax Office, which concern approximately €215 million (approximately $241 million) of tax benefits that we have claimed related to a 1998 reorganization of the corporate structure of Otis operations in Germany. Upon audit, these tax benefits were disallowed by the German Tax Office. UTC estimates interest associated with the aforementioned tax benefits is an additional approximately €118 million (approximately $133 million). On August 3, 2012, we filed suit in the local German Tax Court (Berlin-Brandenburg). In 2008 the German Federal Tax Court (FTC) denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the FTC on this other matter was appealed to the European Court of Justice (ECJ) to determine if the underlying German tax law is violative of European Union principles. On September 17, 2009, the ECJ issued an opinion in this case that is generally favorable to the other taxpayer and referred the case back to the FTC for further consideration of certain related issues. In May 2010, the FTC released its decision, in which it resolved certain tax issues that may be relevant to our suit and remanded the case to a lower court for further development. In 2012, the lower court decided in favor of the other taxpayer and the German Government again appealed the findings to the FTC. In November 2014, the FTC ruled in favor of the German Government, and against the other taxpayer. We believe that the FTC decision in the case involving the other taxpayer is not determinative of the outcome in our case, and we will continue vigorously to litigate the matter. However, in light of the FTC decision in the case involving the other taxpayer, we fully accrued for the matter during the quarter ended December 31, 2014. While we continue to litigate the matter at the local German Tax Court, UTC made tax and interest payments to German tax authorities of €38 million (approximately $42 million) in the quarter ended September 30, 2015. UTC has made aggregate tax and interest payments to the German tax authorities of €275 million (approximately $300 million) through September 30, 2015 (including the payments noted in the immediately preceding sentence) to avoid additional interest accruals pending final resolution of this matter. Other. As described in Note 16 to the Consolidated Financial Statements in our 2014 Annual Report, we extend performance and operating cost guarantees beyond our normal warranty and service policies for extended periods on some of our products. We have accrued our estimate of the liability that may result under these guarantees and for service costs that are probable and can be reasonably estimated. We have accrued for environmental investigatory, remediation, operating and maintenance costs, performance guarantees and other litigation and claims based on our estimate of the probable outcome of these matters. While it is possible that the outcome of these matters may differ from the recorded liability, we believe that resolution of these matters will not have a material impact on our competitive position, results of operations, cash flows or financial condition. We also have other commitments and contingent liabilities related to legal proceedings, self-insurance programs and matters arising out of the normal course of business. We accrue contingencies based upon a range of possible outcomes. If no amount within this range is a better estimate than any other, then we accrue the minimum amount. We are also subject to a number of routine lawsuits, investigations and claims (some of which involve substantial amounts) arising out of the ordinary course of our business. We do not believe that these matters will have a material adverse effect upon our competitive position, results of operations, cash flows or financial condition.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09, "Revenue from Contracts with Customers." This ASU is intended to clarify the principles for recognizing revenue by removing inconsistencies in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. On August 12, 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which delays the effective date of ASU 2014-09 by one year. The new standard is effective for reporting periods beginning after December 15, 2017. Early application is permitted for reporting periods beginning after December 15, 2016. We are evaluating the impact of ASU 2014-09 . In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis." This update is intended to improve targeted areas of consolidation guidance by simplifying the consolidation evaluation process, and by placing more emphasis on risk of loss when determining a controlling financial interest. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2015. We are currently evaluating the impact of this ASU. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This ASU more closely aligns the treatment of debt issuance costs with debt discounts and premiums and requires debt issuance costs be presented as a direct deduction from the carrying amount of the related debt. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. This ASU is not expected to have a significant impact on our financial statements or disclosures. In July 2015, FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” This ASU changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business; less reasonably predictable costs of completion, disposal and transportation. The provisions of this ASU are effective for years beginning after December 15, 2016. This ASU is not expected to have a significant impact on our financial statements or disclosures. In September 2015, the FASB issued ASU 2015-16, “Business Combinations: Simplifying the Accounting For Measurement Period Adjustments.” This ASU requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in this ASU are effective for fiscal years beginning after December 15, 2015. This ASU is not expected to have a significant impact on our financial statements or disclosures.

Department of Justice Lawsuit Against Pratt and Whitney [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date		1,999
Loss Contingency Allegations		As previously disclosed, the United States Government sued us in 1999 in the United States District Court for the Southern District of Ohio, claiming that Pratt & Whitney violated the civil False Claims Act and common law. The claims relate to the “Fighter Engine Competition” between Pratt & Whitney's F100 engine and General Electric's F110 engine. The government alleged that it overpaid for F100 engines under contracts awarded by the U.S. Air Force in fiscal years 1985 through 1990 because Pratt & Whitney inflated its estimated costs for some purchased parts and withheld data that would have revealed the overstatements. At trial, which ended in April 2005, the government claimed Pratt & Whitney's liability to be approximately $624 million.
Loss Contingency Actions Taken By Court Arbitrator Or Mediator		On August 1, 2008, the trial court held that the Air Force had not suffered any actual damages because Pratt & Whitney had made significant price concessions after the alleged overstatements were made. However, the trial court judge found that Pratt & Whitney violated the False Claims Act due to inaccurate statements contained in its 1983 initial engine pricing proposal. In the absence of actual damages, the trial court awarded the government the maximum civil penalty of $7,090,000, or $10,000 for each of the 709 invoices Pratt & Whitney submitted in 1989 and later under the contracts.
Loss Contingency Actions Taken By Plaintiff And Defendant		In September 2008, both the government and UTC appealed the decision to the United States Court of Appeals for the Sixth Circuit. In November 2010, the Sixth Circuit affirmed Pratt & Whitney's liability for the civil penalty under the False Claims Act, but remanded the case to the trial court for further proceedings on the issues of False Claims Act damages and common law liability and damages.
Loss Contingency, Additional Actions Taken by Court, Arbitrator or Mediator		On June 18, 2012, the trial court found that Pratt & Whitney had breached obligations imposed by common law based on the same conduct with respect to which the court previously found liability under the False Claims Act. Under the common law claims, the U.S. Air Force seeks damages for events occurring before March 3, 1989, which are not recoverable under the False Claims Act.
Loss Contingency, Settlement Agreement, Terms		On June 17, 2013, the trial court awarded the government approximately $473 million in damages and penalties, plus prejudgment interest in an amount to be determined. On July 1, 2013, the trial court, after determining the amount of prejudgment interest, entered judgment in favor of the government in the amount of approximately $664 million. The trial court also awarded post-judgment interest on the full amount of the judgment to accrue from July 2, 2013, at the federal variable interest rate determined pursuant to 28 U.S.C. § 1961. The judgment included four different components: (1) common law damages of approximately $109 million; (2) prejudgment interest on common law damages of approximately $191 million; (3) False Claims Act treble damages of approximately $357 million; and (4) the civil penalty of approximately $7 million. The penalty component of the judgment previously was affirmed by the United States Court of Appeals in 2010.
Loss Contingency Damages Sought		624
Loss Contingency, Period of Occurrence		fiscal years 1985 through 1990
Loss Contingency Actions Taken By Defendant		We filed an appeal from the judgment to the United States Court of Appeals for the Sixth Circuit on August 26, 2013. On April 6, 2015, the Sixth Circuit reversed the trial court’s decision and vacated the prior damages award, noting that the government did not prove any damages. The court rejected as a matter of law the evidence submitted by the government on damages and remanded the case to the trial court to decide in the first instance whether the government should have another opportunity to prove that it suffered any actual damages. On July 17, 2015, the case returned to the District Court, at which time we filed a motion for entry of judgment, seeking a judgment of zero actual damages. The government responded by filing a motion on August 28, 2015, in which it abandoned its claim for actual damages, but now seeks a judgment of approximately $85 million, representing (1) disgorgement of UTC’s alleged profits in fiscal year 1985, the first year of the multi-year engine competition, (2) prejudgment interest and (3) the civil penalty. We continue to believe that the government suffered no actual damages as a result of the inaccurate statements made in 1983. We also believe that there is no basis for the government’s new profit disgorgement claim. Accordingly, we continue not to accrue a reserve beyond the approximately $7 million civil penalty referenced above.

U.S. Defense Contract Management Agency Claim Against Pratt & Whitney [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date		December 24, 2013
Loss Contingency Allegations		By letter dated December 24, 2013, a Divisional Administrative Contracting Officer of the United States Defense Contract Management Agency asserted a claim and demand for payment of approximately $211 million against Pratt & Whitney. The claim is based on Pratt & Whitney's alleged noncompliance with cost accounting standards from January 1, 2005 to December 31, 2012, due to its method of determining the cost of collaborator parts used in the calculation of material overhead costs for government contracts.
Loss Contingency Damages Sought		$211 million
Loss Contingency Actions Taken By Defendant		We believe this claim is without merit. On March 18, 2014, Pratt & Whitney filed an appeal to the Armed Services Board of Contract Appeals.
German Tax Office Against Otis [Member]
Loss Contingencies [Line Items]
Loss Contingency Lawsuit Filing Date		August 3, 2012
Loss Contingency Allegations		As previously disclosed, UTC has been involved in administrative review proceedings with the German Tax Office, which concern approximately €215 million (approximately $241 million) of tax benefits that we have claimed related to a 1998 reorganization of the corporate structure of Otis operations in Germany. Upon audit, these tax benefits were disallowed by the German Tax Office. UTC estimates interest associated with the aforementioned tax benefits is an additional approximately €118 million (approximately $133 million).
Loss Contingency Actions Taken By Plaintiff And Defendant		On August 3, 2012, we filed suit in the local German Tax Court (Berlin-Brandenburg). In 2008 the German Federal Tax Court (FTC) denied benefits to another taxpayer in a case involving a German tax law relevant to our reorganization. The determination of the FTC on this other matter was appealed to the European Court of Justice (ECJ) to determine if the underlying German tax law is violative of European Union principles. On September 17, 2009, the ECJ issued an opinion in this case that is generally favorable to the other taxpayer and referred the case back to the FTC for further consideration of certain related issues. In May 2010, the FTC released its decision, in which it resolved certain tax issues that may be relevant to our suit and remanded the case to a lower court for further development. In 2012, the lower court decided in favor of the other taxpayer and the German Government again appealed the findings to the FTC. In November 2014, the FTC ruled in favor of the German Government, and against the other taxpayer. We believe that the FTC decision in the case involving the other taxpayer is not determinative of the outcome in our case, and we will continue vigorously to litigate the matter. However, in light of the FTC decision in the case involving the other taxpayer, we fully accrued for the matter during the quarter ended December 31, 2014.
Loss Contingency Damages Sought		€215 million (approximately $241 million)
Loss Contingency Actions Taken By Defendant		While we continue to litigate the matter at the local German Tax Court, UTC made tax and interest payments to German tax authorities of €38 million (approximately $42 million) in the quarter ended September 30, 2015.  UTC has made aggregate tax and interest payments to the German tax authorities of €275 million (approximately $300 million) through September 30, 2015 (including the payments noted in the immediately preceding sentence) to avoid additional interest accruals pending final resolution of this matter.
