SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended
	Apr. 30, 2021
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, 2020. The October 31, 2020 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 six months ended April 30, 2021 are not necessarily indicative of the results which may be expected for the entire fiscal year. Certain immaterial prior year amounts within the Condensed Consolidated Statements of Cash Flows have been reclassified to conform to the current year presentation and resulted in no changes to total Net cash provided by operating activities, Net cash used in investing activities and Net cash (used in) provided by financing activities. The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. and their respective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. (“HEICO Electronic”) and its subsidiaries. The Company's results of operations in the first six months and second quarter of fiscal 2021 continue to reflect the adverse impact from the COVID-19 global pandemic (the “Pandemic”). Most notably, demand for HEICO's commercial aviation products and services continues to be moderated by the ongoing depressed commercial aerospace market. Consolidated net sales for the Company's businesses that operate within the commercial aerospace industry decreased by approximately 30% and 14% in the first six months and second quarter of fiscal 2021, respectively, as compared to the first six months and second quarter of fiscal 2020. As we look ahead to the remainder of fiscal 2021, the Company is cautiously optimistic that the ongoing worldwide rollout of COVID-19 vaccines will have a positive influence on commercial air travel and generate favorable economic environments in the markets it serves. However, the pace of recovery in global travel remains difficult to predict and can be negatively influenced by new COVID-19 variants and varying vaccine adoption rates. However, the Company believes its ongoing fiscal conservative policies, strong balance sheet, and high degree of liquidity enable it to invest in new research and development, execute on its successful acquisition program, and position HEICO for market share gains as the industry recovers.

ACQUISITIONS

ACQUISITIONS	6 Months Ended
	Apr. 30, 2021
Business Combinations [Abstract]
Acquisitions [Text Block]	ACQUISITION In March 2021, the Company, through HEICO Electronic, acquired all of the business, assets and certain liabilities of Pyramid Semiconductor LLC ("Pyramid"). Pyramid is a specialty semiconductor designer and manufacturer offering a well-developed line of processors, static random-access memory (SRAM), electronically erasable programmable read-only memory (EEPROM) and Logic products on a diverse array of military, space and medical platforms. The purchase price of Pyramid was paid in cash using cash provided by operating activities, and is not material or significant to the Company's condensed consolidated financial statements. The allocation of the total consideration for Pyramid to the tangible and identifiable intangible assets acquired and liabilities assumed is preliminary until the Company obtains final information regarding their fair values. However, the Company does not expect any adjustment to such allocations to be material to the Company's consolidated financial statements. The operating results of Pyramid were included in the Company’s results of operations from the effective acquisition date. The amount of net sales and earnings of Pyramid included in the Condensed Consolidated Statements of Operations for the six and three months ended April 30, 2021 is not material. Had the Pyramid acquisition occurred as of November 1, 2019, 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 six and three months ended April 30, 2021 and 2020 would not have been materially different than the reported amounts.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE Contract Balances Contract assets (unbilled receivables) represent revenue recognized on contracts using an over-time recognition model in excess of amounts invoiced to the customer. Contract liabilities (deferred revenue) represent customer advances and billings in excess of revenue recognized and are included within accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets. Changes in the Company’s contract assets and liabilities for the six months ended April 30, 2021 are as follows (in thousands): April 30, 2021 October 31, 2020 Change Contract assets $59,881 $60,429 ($548) Contract liabilities 31,451 25,631 5,820 Net contract assets $28,430 $34,798 ($6,368) The increase in the Company's contract liabilities during the first six months of fiscal 2021 mainly occurred within the ETG and principally reflects the receipt of new customer deposits on certain customer contracts in excess of reductions to contract liabilities from customer deposits recognized as revenue. The amount of revenue that the Company recognized during the six and three months ended April 30, 2021 that was included in contract liabilities as of the beginning of fiscal 2021 was $14.9 million and $3.7 million, respectively. Remaining Performance Obligations As of April 30, 2021, the Company had $451.2 million of remaining performance obligations associated with contracts with an original duration of greater than one year pertaining to the majority of the products offered by the ETG as well as certain products of the FSG's specialty products and aftermarket replacement parts product lines. The Company will recognize net sales as these obligations are satisfied. The Company expects to recognize $219.6 million of this amount during the remainder of fiscal 2021 and $231.6 million thereafter, of which the majority is expected to occur in fiscal 2022.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES The Company's effective tax rate in the first six months of fiscal 2021 was 12.0%, as compared to .3% in the first six months of fiscal 2020. The Company recognized a discrete tax benefit from stock option exercises in both the first quarter of fiscal 2021 and 2020 of $13.5 million and $47.6 million, respectively. The tax benefit from stock option exercises in both periods was the result of strong appreciation in HEICO's stock price during the optionees' holding periods and the $34.1 million larger benefit recognized in the first quarter of fiscal 2020 was the result of more stock options exercised. Additionally, the effective tax rate in the first six months of fiscal 2021 reflects the favorable impact of higher tax-exempt unrealized gains in the cash surrender values of life insurance policies related to the HEICO Leadership Compensation Plan ("HEICO LCP"). The Company's effective tax rate decreased to 19.5% in the second quarter of fiscal 2021, down from 22.6% in the second quarter of fiscal 2020. The decrease principally reflects the favorable impact of higher tax-exempt unrealized gains in the cash surrender values of life insurance policies related to the HEICO LCP.

The assets of 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 LCP are held within an irrevocable trust and classified within other assets in the Company’s Condensed Consolidated Balance Sheets. The related liabilities of the LCP are included within other long-term liabilities and accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $229.3 million as of April 30, 2021 and $178.3 million as of October 31, 2020. As part of the agreement to acquire 89.99% of the equity interests of a subsidiary by the ETG in fiscal 2020, the Company may be obligated to pay contingent consideration of up to CAD $27.0 million, or $22.0 million, in fiscal 2025 should the acquired entity meet certain earnings objectives during fiscal 2023 and 2024. However, should the acquired entity achieve a certain earnings objective over any two consecutive fiscal years beginning in fiscal 2021 and ending in fiscal 2023, half of the contingent consideration obligation, or CAD $13.5 million, would be payable in the following year. As of April 30, 2021, the estimated fair value of the contingent consideration was CAD $13.3 million, or $10.8 million. As part of the agreement to acquire a subsidiary by the ETG in fiscal 2020, the Company may be obligated to pay contingent consideration of up to $35.0 million in fiscal 2025 based on the earnings of the acquired entity during calendar years 2023 and 2024 provided the entity meets certain earnings objectives during each of calendar years 2021 to 2024. As of April 30, 2021, the estimated fair value of the contingent consideration was $14.3 million. The obligation to pay any contingent consideration would be payable by a consolidated subsidiary of HEICO that is 75% owned by HEICO Electronic. As part of the agreement to acquire a subsidiary by the ETG in fiscal 2017, the Company may be obligated to pay contingent consideration of $20.0 million in fiscal 2023 should the acquired entity meet a certain earnings objective during the first six years following the acquisition. As of April 30, 2021, the estimated fair value of the contingent consideration was $18.3 million. The following unobservable inputs were used to derive the estimated fair value of the Company's Level 3 contingent consideration liabilities as of April 30, 2021 ($ in thousands): Weighted Acquisition Date Fair Value Unobservable Input Range Average (1) 8-18-2020 $10,821 Compound annual revenue growth rate 0% - 19% 7% Discount rate 4.4% - 4.9% 4.6% 8-11-2020 14,304 Compound annual revenue growth rate 4% - 18% 13% Discount rate 4.9% - 4.9% 4.9% 9-15-2017 18,332 Compound annual revenue growth rate (3%) - 10% 6% Discount rate 3.6% - 3.6% 3.6% (1) Unobservable inputs were weighted by the relative fair value of the contingent consideration liability. Changes in the Company’s contingent consideration liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the six months ended April 30, 2021 are as follows (in thousands): Liabilities Balance as of October 31, 2020 $41,974 Foreign currency transaction adjustments 824 Increase in accrued contingent consideration 659 Balance as of April 30, 2021 $43,457 The Company's contingent consideration liabilities are included in other long-term liabilities in its Condensed Consolidated Balance Sheet and the Company records changes in accrued contingent consideration and foreign currency transaction adjustments within selling, general and administrative expenses in its Condensed Consolidated Statement of Operations. 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 April 30, 2021 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.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of Presentation [Text Block]	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, 2020. The October 31, 2020 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 six months ended April 30, 2021 are not necessarily indicative of the results which may be expected for the entire fiscal year. Certain immaterial prior year amounts within the Condensed Consolidated Statements of Cash Flows have been reclassified to conform to the current year presentation and resulted in no changes to total Net cash provided by operating activities, Net cash used in investing activities and Net cash (used in) provided by financing activities. The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. and their respective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. (“HEICO Electronic”) and its subsidiaries. The Company's results of operations in the first six months and second quarter of fiscal 2021 continue to reflect the adverse impact from the COVID-19 global pandemic (the “Pandemic”). Most notably, demand for HEICO's commercial aviation products and services continues to be moderated by the ongoing depressed commercial aerospace market. Consolidated net sales for the Company's businesses that operate within the commercial aerospace industry decreased by approximately 30% and 14% in the first six months and second quarter of fiscal 2021, respectively, as compared to the first six months and second quarter of fiscal 2020. As we look ahead to the remainder of fiscal 2021, the Company is cautiously optimistic that the ongoing worldwide rollout of COVID-19 vaccines will have a positive influence on commercial air travel and generate favorable economic environments in the markets it serves. However, the pace of recovery in global travel remains difficult to predict and can be

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncements, Policy [Policy Text Block]	In January 2017, the Financial Accounting Standards Board issued Accounting Standards Update "ASU" 2017-04, "Simplifying the Test for Goodwill Impairment," which is intended to simplify the current test for goodwill impairment by eliminating the second step in which the implied value of a reporting unit is calculated when the carrying value of the reporting unit exceeds its fair value. Under ASU 2017-04, goodwill impairment should be recognized for the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The Company adopted ASU 2017-04 in the first quarter of fiscal 2021 and will apply the guidance on a prospective basis when assessing its goodwill for impairment.

The assets of 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 LCP are held within an irrevocable trust and classified within other assets in the Company’s Condensed Consolidated Balance Sheets. The related liabilities of the LCP are included within other long-term liabilities and accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $229.3 million as of April 30, 2021 and $178.3 million as of October 31, 2020. As part of the agreement to acquire 89.99% of the equity interests of a subsidiary by the ETG in fiscal 2020, the Company may be obligated to pay contingent consideration of up to CAD $27.0 million, or $22.0 million, in fiscal 2025 should the acquired entity meet certain earnings objectives during fiscal 2023 and 2024. However, should the acquired entity achieve a certain earnings objective over any two consecutive fiscal years beginning in fiscal 2021 and ending in fiscal 2023, half of the contingent consideration obligation, or CAD $13.5 million, would be payable in the following year. As of April 30, 2021, the estimated fair value of the contingent consideration was CAD $13.3 million, or $10.8 million. As part of the agreement to acquire a subsidiary by the ETG in fiscal 2020, the Company may be obligated to pay contingent consideration of up to $35.0 million in fiscal 2025 based on the earnings of the acquired entity during calendar years 2023 and 2024 provided the entity meets certain earnings objectives during each of calendar years 2021 to 2024. As of April 30, 2021, the estimated fair value of the contingent consideration was $14.3 million. The obligation to pay any contingent consideration would be payable by a consolidated subsidiary of HEICO that is 75% owned by HEICO Electronic. As part of the agreement to acquire a subsidiary by the ETG in fiscal 2017, the Company may be obligated to pay contingent consideration of $20.0 million in fiscal 2023 should the acquired entity meet a certain earnings objective during the first six years following the acquisition. As of April 30, 2021, the estimated fair value of the contingent consideration was $18.3 million. The following unobservable inputs were used to derive the estimated fair value of the Company's Level 3 contingent consideration liabilities as of April 30, 2021 ($ in thousands): Weighted Acquisition Date Fair Value Unobservable Input Range Average (1) 8-18-2020 $10,821 Compound annual revenue growth rate 0% - 19% 7% Discount rate 4.4% - 4.9% 4.6% 8-11-2020 14,304 Compound annual revenue growth rate 4% - 18% 13% Discount rate 4.9% - 4.9% 4.9% 9-15-2017 18,332 Compound annual revenue growth rate (3%) - 10% 6% Discount rate 3.6% - 3.6% 3.6% (1) Unobservable inputs were weighted by the relative fair value of the contingent consideration liability. Changes in the Company’s contingent consideration liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the six months ended April 30, 2021 are as follows (in thousands): Liabilities Balance as of October 31, 2020 $41,974 Foreign currency transaction adjustments 824 Increase in accrued contingent consideration 659 Balance as of April 30, 2021 $43,457 The Company's contingent consideration liabilities are included in other long-term liabilities in its Condensed Consolidated Balance Sheet and the Company records changes in accrued contingent consideration and foreign currency transaction adjustments within selling, general and administrative expenses in its Condensed Consolidated Statement of Operations. 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 April 30, 2021 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.
