How do I save changes in an aircraft file?

Use the Enter key to move from one section to another. The section marked with red is the one being editable. Whenever you have made the changes, you need to press “End” on your keyboard – or press Enter until you are at the bottom of the menu. Then you will see the below message:

Press the key “Y” on your keyboard to save the changes. If you do not want to save the changes press “N”.
It is important to make sure the change(s) you make are saved. Double check before moving on to the next
section.
