Final answer:
The legal transfer of aircraft title is done through a bill of sale, which serves as evidence of the transfer of ownership.
Step-by-step explanation:
The legal transfer of aircraft title is typically done through a bill of sale. A bill of sale is a legal document that outlines the terms and conditions of the sale and transfer of ownership. In the context of aircraft, it proves that the buyer now holds the legal title to the aircraft.
For example, if John wants to sell his airplane to Mary, they would complete and sign a bill of sale, which includes details such as the names of the buyer and seller, the purchase price, and the aircraft's information. This document serves as evidence of the transfer of ownership.
