When identifying yourself in an air-ground call, what information should you convey?

• A. Your identity only.
• B. Your call sign and your position/altitude.
• C. Your speed and heading.
• D. Your fuel on board.

Answer: (B)

When you identify yourself over air-ground, you must provide who you are and where you are. Your call sign uniquely identifies your aircraft, and your position plus altitude tells the controller where you are in space. This combination lets the ground station know exactly who you are and how to manage your traffic safely.

For example, you would say your call sign and then your location and altitude, such as “ABC123, five miles northeast of the field, at 3,500 feet.” Speed, heading, or fuel on board aren’t part of the identification itself and aren’t needed to identify you at the moment; they’re information you might convey in subsequent messages or other parts of the transmission if required.
