Business Combination and Asset Acquisition [Abstract]
Business Acquisition	Business AcquisitionOn April 15, 2022, we acquired Pipistrel, a manufacturer of electrically powered aircraft, for a cash purchase price of $239 million, which included the assumption of $35 million of debt and other contractual obligations under the agreement and a final fixed payment of $21 million due in 2024. Beginning in the second quarter of 2022, this business is included in a new reporting segment, Textron eAviation, which combines the operating results of Pipistrel along with other research and development initiatives related to sustainable aviation solutions. We allocated the purchase price for this business to the assets acquired and liabilities assumed based on their estimated fair values at the acquisition date and recorded $141 million in goodwill, related to expected synergies and the value of the assembled workforce, and $76 million in intangible assets, primarily developed technologies. The intangible assets were primarily valued using the relief-from-royalty method. This method utilizes significant unobservable inputs, or Level 3 inputs, as defined by the fair value hierarchy and requires us to make estimates and assumptions about sales, growth rates, royalty rates and discount rates based on marketplace data.
