Summary of Significant Accounting Policies [Text Block]	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements of HEICO Corporation and its subsidiaries (collectively, “HEICO,” or the “Company”) have been prepared in conformity with accounting principles generally accepted in the United States of America for interim financial information and in accordance with the instructions to Form 10-Q. Therefore, the condensed consolidated financial statements do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended October 31, 2013. The October 31, 2013 Condensed Consolidated Balance Sheet has been derived from the Company’s audited consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of operations, statements of comprehensive income, statements of shareholders' equity and statements of cash flows for such interim periods presented. The results of operations for the nine months ended July 31, 2014 are not necessarily indicative of the results which may be expected for the entire fiscal year.
	Stock Split
	All applicable fiscal 2013 share and per share information has been adjusted retrospectively to reflect a 5-for-4 stock split effected in October 2013.
	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires disclosure about changes in and amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The Company adopted ASU 2013-02 in the first quarter of fiscal 2014, resulting in only expanded disclosure regarding the changes in accumulated other comprehensive income and no impact on the Company's consolidated results of operations, financial position or cash flows.
	In March 2013, the FASB issued ASU 2013-05, “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” which clarifies the applicable guidance for the release of any cumulative translation adjustments into net earnings. ASU 2013-05 specifies that the entire amount of cumulative translation adjustments should be released into earnings when an entity ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the investment in the foreign entity. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013, or in fiscal 2015 for HEICO. Early adoption is permitted. The Company is currently evaluating the effect, if any, the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which provides a comprehensive new revenue recognition model that will supersede nearly all existing revenue recognition guidance. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2016, or in fiscal 2018 for HEICO. Early adoption is not permitted. ASU 2014-09 shall be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. The Company is currently evaluating which transition method it will elect and the effect the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.

ACQUISITIONS

Business Acquisition [Line Items]	'
Business Combination Disclosure [Text Block]	'
	ACQUISITION
	In June 2014, the Company, through a subsidiary of its HEICO Flight Support Corp. subsidiary, acquired certain assets and liabilities of Quest Aviation Supply, Inc. (“Quest Aviation”). Quest Aviation is a niche supplier of parts to repair thrust reversers on various aircraft engines. The purchase price of this acquisition was paid in cash, principally using proceeds from the Company's revolving credit facility.
	The total consideration and related allocation to the tangible and identifiable intangible assets acquired and liabilities assumed for the acquisition of Quest Aviation is not material or significant to the Company’s condensed consolidated financial statements. The operating results of Quest Aviation were included in the Company’s results of operations from the effective acquisition date. The amount of net sales and earnings of Quest Aviation included in the Condensed Consolidated Statement of Operations is not material. Had the Quest Aviation acquisition been consummated as of November 1, 2012, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for the nine and three months ended July 31, 2014 and 2013 would not have been materially different than the reported amounts.

The total customer rebates and credits deducted within net sales for the nine months ended July 31, 2014 and 2013 was $5.3 million and $6.0 million, respectively. The total customer rebates and credits deducted within net sales for the three months ended July 31, 2014 and 2013 was $1.9 million and $2.5 million, respectively.

	Redeemable Noncontrolling Interests
	The holders of equity interests in certain of the Company's subsidiaries have put rights that may be exercised on varying dates causing the Company to give cash consideration to purchase their equity interests based on fair value or a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. Management's estimate of the aggregate redemption amount of all put rights that the Company could be required to pay at varying dates through fiscal 2022 is as follows (in thousands):
		31-Jul-14			31-Oct-13
	Redeemable at fair value		$27,969			$47,839
	Redeemable based on a multiple of future earnings	10,136			11,379
	Redeemable noncontrolling interests		$38,105			$59,218
	The decrease in the aggregate redemption amount of put rights redeemable at fair value since the prior fiscal year end principally reflects a reclassification of the redemption amount pertaining to the equity interest in one of the Company's subsidiaries from redeemable noncontrolling interests (temporary equity) to noncontrolling interests (permanent equity) upon the expiration of the holder's put right in the second quarter of fiscal 2014.

	Balances as of July 31, 2014		$282,407		$406,916			$689,323
	The goodwill acquired pertains to the current year acquisition described in Note 2, Acquisition, and represents the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities assumed. The Company estimates that all of the goodwill acquired in fiscal 2014 will be deductible for income tax purposes.

	The decrease in the gross carrying amount of customer relationships and non-amortizing trade names reflects impairment losses of $7.5 million and $1.7 million, respectively, recognized during the third quarter of fiscal 2014. The impairment losses were due to reductions in the future cash flows associated with such intangible assets within the ETG and were recorded as a component of selling, general and administrative expenses in the Company's Condensed Consolidated Statement of Operations.
	Amortization expense related to intangible assets for the nine months ended July 31, 2014 and 2013 was $21.1 million and $14.3 million, respectively. Amortization expense related to intangible assets for the three months ended July 31, 2014 and 2013 was $7.0 million and $5.4 million, respectively. The increase in amortization expense for the nine and three months ended July 31, 2014 compared to the nine and three months ended July 31, 2013 principally relates to the incremental amortization expense of intangible assets recognized in connection with fiscal 2013 acquisitions. Amortization expense related to intangible assets for the remainder of fiscal 2014 is estimated to be $6.6 million. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $24.8 million in fiscal 2015, $23.0 million in fiscal 2016, $22.1 million in fiscal 2017, $20.2 million in fiscal 2018, $18.1 million in fiscal 2019 and $44.3 million thereafter.

The revolving credit facility contains both financial and non-financial covenants. As of July 31, 2014, the Company was in compliance with all such covenants.
	In November 2013, the Company entered into an amendment to extend the maturity date of its revolving credit facility by one year to December 2018 and to increase the aggregate principal amount to $800 million. Furthermore, the amendment includes a feature that will allow the Company to increase the aggregate principal amount by an additional $200 million to become a $1.0 billion facility through increased commitments from existing lenders or the addition of new lenders.

	INCOME TAXES
	As of July 31, 2014, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $1.0 million of which $.7 million would decrease the Company’s income tax expense and effective income tax rate if the tax benefits were recognized. A reconciliation of the activity related to the liability for gross unrecognized tax benefits for the nine months ended July 31, 2014 is as follows (in thousands):
	Balance as of October 31, 2013		$1,072
	Increases related to current year tax positions	81
	Settlements	(22		)
	Lapse of statutes of limitations	(94		)
	Balance as of July 31, 2014		$1,037
	There were no material changes in the liability for unrecognized tax positions resulting from tax positions taken during the current or a prior year, settlements with other taxing authorities or a lapse of applicable statutes of limitations. The accrual of interest and penalties related to the unrecognized tax benefits was not material for the nine months ended July 31, 2014. Further, the Company does not expect the total amount of unrecognized tax benefits to materially change in the next twelve months.
	The Company's effective tax rate in the first nine months of fiscal 2014 increased to 29.7% from 29.5% in the first nine months of fiscal 2013. The increase is principally due to an income tax credit for qualified research and development activities for the last ten months of fiscal 2012 that was recognized in the first quarter of fiscal 2013 resulting from the retroactive extension of the U.S research and development tax credit and its subsequent expiration on December 31, 2013 that limited the tax credit recognized in fiscal 2014 to just two months. Additionally, the increase reflects a larger income tax deduction recognized in the prior year for the special and extraordinary cash dividend paid to participants of the HEICO Savings and Investment Plan ("SIP") holding HEICO common stock and the benefit in the prior year from higher tax-exempt unrealized gains in the cash surrender values of life insurance policies related to the HEICO Corporation Leadership Compensation Plan ("LCP"). These increases to the effective tax rate were partially offset by the impact of a nontaxable reduction in accrued contingent consideration during fiscal 2014 associated with a fiscal 2013 acquisition acquired by means of a stock transaction.
	The Company's effective tax rate in the third quarter of fiscal 2014 decreased to 23.4% from 26.6% in the third quarter of fiscal 2013. The decrease is principally attributed to the previously mentioned reduction in accrued contingent consideration partially offset by the previously mentioned lower research and development tax credits recognized in fiscal 2014 due to expiration of the U.S. research and development tax credit, larger prior year income tax deduction for the cash dividends paid to participants of the HEICO SIP and higher tax-exempt unrealized gains in the prior year related to the LCP.

	The Company maintains two non-qualified deferred compensation plans. The assets of the HEICO Corporation Leadership Compensation Plan (the “LCP”) principally represent cash surrender values of life insurance policies, which derive their fair values from investments in mutual funds that are managed by an insurance company and are classified within Level 2 and valued using a market approach. Certain other assets of the LCP represent investments in money market funds that are classified within Level 1. The assets of the Company’s other deferred compensation plan are principally invested in equity securities, mutual funds, and money market deposit accounts that are classified within Level 1. The assets of both plans are held within irrevocable trusts and classified within other assets in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $69.3 million as of July 31, 2014 and $57.6 million as of October 31, 2013, of which the LCP related assets were $63.8 million and $52.7 million as of July 31, 2014 and October 31, 2013, respectively. The related liabilities of the two deferred compensation plans are included within other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $68.5 million as of July 31, 2014 and $56.9 million as of October 31, 2013, of which the LCP related liability was $63.0 million and $51.9 million as of July 31, 2014 and October 31, 2013, respectively.
	As part of the agreement to acquire a subsidiary by the ETG in fiscal 2013, the Company may have been obligated to pay contingent consideration of up to $20.0 million had the acquired entity met certain earnings objectives during the last three months of the calendar year of acquisition and may be obligated to pay contingent consideration of up to $30.0 million should the acquired entity meet certain earnings objectives during each of the next two calendar years (2014 and 2015). In December 2013, the acquired entity incurred unanticipated costs associated with certain contracts for which revenue is recognized on the percentage-of-completion method and as a result, did not meet its calendar 2013 related earnings objectives. Accordingly, the $7.0 million contingent consideration accrued as of October 31, 2013 was recorded as a reduction to selling, general and administrative expenses ("SG&A") in the Company's Condensed Consolidated Statement of Operations in the first quarter of fiscal 2014. The estimated fair value of the contingent consideration for the calendar 2014 and 2015 earnings period was $1.2 million as of July 31, 2014 compared to $13.7 million as of October 31, 2013. The aggregate $12.5 million decrease is principally attributed to revised earnings estimates that reflect less favorable projected market conditions resulting in fair value adjustments of $2.3 million and $10.2 million recorded as reductions to SG&A expenses in the second and third quarters of fiscal 2014, respectively.
	As part of the agreement to acquire a subsidiary by the ETG in fiscal 2012, the Company may be obligated to pay contingent consideration of up to $10.6 million in aggregate should the acquired entity meet certain earnings objectives during each of the next three years following the second anniversary date of the acquisition. As of July 31, 2014 and October 31, 2013, the estimated fair value of the contingent consideration was $8.6 million.
	The estimated fair values of the contingent consideration arrangements described above are classified within Level 3 and were determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings was determined using internal estimates based on various revenue growth rate assumptions for each scenario. A probability of likelihood was assigned to each discrete potential future earnings estimate and the resultant contingent consideration was calculated. The resulting probability-weighted contingent consideration amounts were discounted using a weighted average discount rate reflecting the credit risk of a market participant. Changes in either the revenue growth rates, related earnings or the discount rate could result in a material change to the amount of contingent consideration accrued and such changes will be recorded in the Company's condensed consolidated statements of operations.
	The Level 3 inputs used to derive the estimated fair values of the contingent consideration as of July 31, 2014 are as follows:
		Fiscal 2013 Acquisition		Fiscal 2012 Acquisition
	Compound annual revenue growth rate range	(2%) - 24%		(5%) - 18%
	Weighted average discount rate	2.90%		3.00%
	Changes in the Company’s contingent consideration measured at fair value on a recurring basis using unobservable inputs (Level 3) for the nine months ended July 31, 2014 are as follows (in thousands):
		Liabilities
	Balance as of October 31, 2013		$29,310
	Decrease in accrued contingent consideration	(19,516		)
	Balance as of July 31, 2014		$9,794
	Included in the accompanying Condensed Consolidated Balance Sheet
	under the following captions:
	Accrued expenses and other current liabilities		$2,090
	Other long-term liabilities	7,704
			$9,794
	The Company did not have any transfers between Level 1 and Level 2 fair value measurements during the nine months ended July 31, 2014.
	The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, trade accounts payable and accrued expenses and other current liabilities approximate fair value as of July 31, 2014 due to the relatively short maturity of the respective instruments. The carrying amount of long-term debt approximates fair value due to its variable interest rates.
	During the third quarter of fiscal 2014, certain customer relationships and a non-amortizing trade name within the ETG were measured at fair value on a nonrecurring basis, resulting in the recognition of impairment losses aggregating $9.2 million (see Note 4, Goodwill and Other Intangible Assets). The fair values of the Company’s nonfinancial assets and liabilities that were measured at fair value on a nonrecurring basis, which are classified within Level 3, and the related impairment losses recognized in the third quarter of fiscal 2014 are as follows (in thousands):
		Carrying Amount			Impairment Loss			Fair Value (Level 3)
	Assets:
	Customer relationships		$15,316			($7,500	)		$7,816
	Non-amortizing trade name	9,500			(1,700		)	7,800
	Impairment of intangible assets					($9,200	)
	The fair values of such customer relationships and non-amortizing trade name were determined using variations of the income approach which apply an asset-specific discount rate to a forecast of asset-specific cash flows. These methods utilize certain significant unobservable inputs categorized as Level 3. The Level 3 inputs used to derive the estimated fair values of the customer relationships and non-amortizing trade name as of July 31, 2014 are as follows:
		Customer Relationships		Non-Amortizing Trade Name
	Valuation method	Excess Earnings		Relief from Royalty
	Discount rate	15.00%		14.00%

	In January 2014, the Company paid a special and extraordinary $.35 per share cash dividend on both classes of HEICO's common stock as well as its regular semi-annual $.06 per share cash dividend. The dividends, which aggregated $27.2 million, were principally funded from borrowings under the Company's revolving credit facility.
	Consistent with the Company's past practice of increasing its ownership in certain non-wholly-owned subsidiaries, on February 18, 2014, HEICO Corporation acquired the 20% noncontrolling interest held by Lufthansa Technik AG (“LHT”) in four of the Company's existing subsidiaries principally operating in the specialty products and distribution businesses within its HEICO Aerospace Holdings Corp. ("HEICO Aerospace") subsidiary (the “Transaction”). Pursuant to the Transaction, HEICO Aerospace paid dividends proportional to the ownership (80%/20%) to HEICO and LHT, and HEICO transferred the businesses to HEICO Flight Support Corp., a wholly-owned subsidiary of HEICO. HEICO did not record any gain or loss in connection with the Transaction. LHT’s dividend of $67.4 million was paid in cash, principally using proceeds from the Company’s revolving credit facility. LHT remains a 20% owner in HEICO Aerospace, a leading producer of PMA parts and component repair and overhaul services.

	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires disclosure about changes in and amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The Company adopted ASU 2013-02 in the first quarter of fiscal 2014, resulting in only expanded disclosure regarding the changes in accumulated other comprehensive income and no impact on the Company's consolidated results of operations, financial position or cash flows.
	In March 2013, the FASB issued ASU 2013-05, “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” which clarifies the applicable guidance for the release of any cumulative translation adjustments into net earnings. ASU 2013-05 specifies that the entire amount of cumulative translation adjustments should be released into earnings when an entity ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the investment in the foreign entity. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013, or in fiscal 2015 for HEICO. Early adoption is permitted. The Company is currently evaluating the effect, if any, the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which provides a comprehensive new revenue recognition model that will supersede nearly all existing revenue recognition guidance. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2016, or in fiscal 2018 for HEICO. Early adoption is not permitted. ASU 2014-09 shall be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. The Company is currently evaluating which transition method it will elect and the effect the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.
