You may also wish to transfer the title of your aircraft between your groups and user account. From the Aircraft page, select the "Transfer" option. A popup box will appear listing the aircraft details, and a transfer drop-down will be listed at the bottom. Select the entity you would like to transfer the aircraft to, and click the "Transfer Aircraft" button to complete.
For temporary usage by other players, consider the option to lease your aircraft to another user or group.
If you want to sell your aircraft, you have three options... 1.) Sell the aircraft back to the Bank of FSEconomy, 2.) Offer the aircraft up for public sale, or 3.) Advertise or negotiate with individuals and set up a private sale.
Each of the below options can be accessed by selecting "Edit" from the Aircraft age, as displayed in the image.
Option 1 - Sell to the Bank - Selling your aircraft back to the Bank of FSE will give you a non-negotiable value. That value is about half of the base aircraft price plus the base price of any installed avionics, adjusted downward based on the number of airframe hours the airplane has been flown. This is usually an option of last resort as the sellback value is often far lower than the fair market price.
Option 2 - Public Sale - You can make your aircraft available for public sale by listing your aircraft on the sale page. Simply type your price in the appropriate box on the aircraft details page, and select the "Public Sale" radio button. Your aircraft will then be available for sale to the open market.
Option 3 - Private Sale - If you have negotiated a price with another player using the forums or private messaging, you can open the airplane up for a private sale. This method is a safe and secure way to sell directly to another player or group. On the aircraft details page, click the "Private Sale" radio button. Add the name of the user or group you are selling to, and enter your price. The named user will not be notified that they have a sale waiting, but they can access it via the Aircraft Sales page's "View Private Sales Offers" button.
