SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended

Accounting Policies [Abstract]
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, 2014. The October 31, 2014 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 three months ended January 31, 2015 are not necessarily indicative of the results which may be expected for the entire fiscal year.
	The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. (“HEICO Aerospace”) and HEICO Flight Support Corp. and their collective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. (“HEICO Electronic”) and its subsidiaries.
	New Accounting Pronouncements
	In March 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. The Company adopted ASU 2013-05 in the first quarter of fiscal 2015, resulting in no impact on the Company's 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.

Business Combinations [Abstract]
Acquisitions [Text Block]	ACQUISITIONS
	In January 2015, the Company, through its HEICO Flight Support Corp. subsidiary, acquired 80% of the equity of Aeroworks International Holdings, B.V. (“Aeroworks”). Aeroworks, which is headquartered in The Netherlands and maintains significant production facilities in Thailand and Laos, is a manufacturer of both composite and metal parts used primarily in aircraft interior applications, including seating, galleys, lavatories, doors, and overhead bins. The remaining 20% interest continues to be owned by a certain member of Aeroworks' management team (see Note 3, Selected Financial Statement Information, for additional information). The total consideration includes an accrual representing the fair value of contingent consideration that the Company may be obligated to pay should Aeroworks meet certain earnings objectives during each of the first four years following the acquisition. See Note 7, Fair Value Measurements, for additional information regarding the Company’s contingent consideration obligation.
	In January 2015, the Company, through its HEICO Flight Support Corp. subsidiary, acquired 80.1% of the equity of Harter Aerospace, LLC ("Harter"). Harter is a globally recognized component and accessory maintenance, repair, and overhaul (MRO) station specializing in commercial aircraft accessories, including thrust reverse actuation systems and pneumatics, and electromechanical components. The remaining 19.9% interest continues to be owned by certain members of Harter's management team (see Note 3, Selected Financial Statement Information, for additional information).
	The purchase price of the Aeroworks and Harter acquisitions were paid in cash principally using proceeds from the Company’s revolving credit facility. The total consideration for the acquisitions of Aeroworks and Harter is not material or significant to the Company’s condensed consolidated financial statements and the related allocation to the tangible and identifiable intangible assets acquired and liabilities and noncontrolling interests assumed is preliminary until the Company obtains final information regarding their fair values.
	The operating results of Aeroworks and Harter were included in the Company’s results of operations from the effective acquisition dates. The amount of net sales and earnings of Aeroworks and Harter included in the Condensed Consolidated Statements of Operations is not material. Had the Aeroworks and Harter acquisitions been consummated as of November 1, 2013, 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 three months ended January 31, 2015 and January 31, 2014 would not have been materially different than the reported amounts.

	The increase in the gross carrying amount of customer relationships, non-amortizing trade names and intellectual property as of January 31, 2015 compared to October 31, 2014 principally relates to such intangible assets recognized in connection with the fiscal 2015 acquisitions (see Note 2, Acquisitions). The weighted-average amortization period of the customer relationships and intellectual property acquired during fiscal 2015 is 9 and 11 years, respectively.
	Amortization expense related to intangible assets for the three months ended January 31, 2015 and 2014 was $6.1 million and $7.1 million, respectively. Amortization expense related to intangible assets for the remainder of fiscal 2015 is estimated to be $19.9 million. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $25.2 million in fiscal 2016, $24.3 million in fiscal 2017, $22.4 million in fiscal 2018, $20.5 million in fiscal 2019, $18.0 million in fiscal 2020, and $38.6 million thereafter.

			$354,552			$328,691
	During the first quarter of fiscal 2015, the Company elected to borrow €32 million under its revolving credit facility, which allows for borrowings made in foreign currencies up to a $50 million sublimit. The funds were used to facilitate an acquisition made during the fiscal quarter. As of January 31, 2015, the United States ("U.S.") dollar equivalent of the Company's Euro borrowing was $36.2 million.
	As of January 31, 2015 and October 31, 2014, the weighted average interest rate on borrowings under the Company’s revolving credit facility was 1.4% and 1.3%, respectively. The revolving credit facility contains both financial and non-financial covenants. As of January 31, 2015, the Company was in compliance with all such covenants.

	As of January 31, 2015, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $.9 million of which $.6 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 three months ended January 31, 2015 is as follows (in thousands):
	Balance as of October 31, 2014		$879
	Increases related to current year tax positions	38
	Increases related to prior year tax positions	14
	Balance as of January 31, 2015		$931
	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 three months ended January 31, 2015. 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 quarter of fiscal 2015 decreased to 29.5% from 33.9% in the first quarter of fiscal 2014. The decrease is principally due to an income tax credit for qualified R&D activities for the last ten months of fiscal 2014 that was recognized in the first quarter of fiscal 2015 resulting from the retroactive extension of the U.S. federal R&D tax credit in December 2014 to cover calendar year 2014.
	The Company has not made a provision for U.S. income taxes on the undistributed earnings of a fiscal 2015 foreign acquisition as such earnings are considered permanently reinvested outside of the U.S. The amount of undistributed earnings is not material to the Company's condensed consolidated financial statements.

	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 deposit accounts that are classified within Level 1. The assets of the Company’s other deferred compensation plan are principally invested in equity securities and mutual funds 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 $78.1 million as of January 31, 2015 and $71.4 million as of October 31, 2014, of which the LCP related assets were $72.5 million and $65.9 million as of January 31, 2015 and October 31, 2014, 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 $77.3 million as of January 31, 2015 and $70.5 million as of October 31, 2014, of which the LCP related liability was $71.7 million and $65.0 million as of January 31, 2015 and October 31, 2014, respectively.
	As part of the agreement to acquire a subsidiary by the FSG in the first quarter of fiscal 2015, the Company may be obligated to pay contingent consideration of up to €24.4 million in aggregate, which translates to approximately $27.7 million based on the January 31, 2015 exchange rate, should the acquired entity meet certain earnings objectives during each of the first four years following the acquisition. As of January 31, 2015, the estimated fair value of the contingent consideration was $20.5 million.
	As part of the agreement to acquire a subsidiary by the ETG in fiscal 2013, the Company may be obligated to pay contingent consideration of up to $30.0 million should the acquired entity meet certain earnings objectives during calendar years 2014 and 2015. The estimated fair value of the contingent consideration was $1.2 million as of January 31, 2015 and October 31, 2014.
	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 value of the Company's contingent consideration liability as of January 31, 2015 were as follows:
		Fiscal 2015 Subsidiary					Fiscal 2013 Subsidiary
	Compound annual revenue growth rate range	(7	%)	-	12%		(7	%)	-	20%
	Weighted average discount rate	2.20%					2.60%
	Changes in the Company’s contingent consideration liability measured at fair value on a recurring basis using unobservable inputs (Level 3) for the three months ended January 31, 2015 are as follows (in thousands):
	Balance as of October 31, 2014		$1,184
	Contingent consideration related to acquisition	21,355
	Increase in accrued contingent consideration	20
	Foreign currency translation adjustments	(835		)
	Balance as of January 31, 2015		$21,724
	Included in the accompanying Condensed Consolidated Balance Sheet
	under the following captions:
	Accrued expenses and other current liabilities		$—
	Other long-term liabilities	21,724
			$21,724
	The Company did not have any transfers between Level 1 and Level 2 fair value measurements during the three months ended January 31, 2015.
	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 January 31, 2015 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.

	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, 2014. The October 31, 2014 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 three months ended January 31, 2015 are not necessarily indicative of the results which may be expected for the entire fiscal year.
	The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. (“HEICO Aerospace”) and HEICO Flight Support Corp. and their collective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. (“HEICO Electronic”) and its subsidiaries.
New Accounting Pronouncements [Text Block]	New Accounting Pronouncements
	In March 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. The Company adopted ASU 2013-05 in the first quarter of fiscal 2015, resulting in no impact on the Company's 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.
