What would a pilot report to Center when asked to identify themselves?

• A. The aircraft's callsign and, if requested, the transponder code or ident.
• B. The aircraft color and tail number.
• C. The destination and route only.
• D. The weather at departure.

Answer: (A)

When ATC asks you to identify yourself, you respond with the aircraft’s callsign and, if requested, the transponder code (squawk) or the ident function. The callsign is the voice identity used in all communications, and the transponder code links that identity to the radar target so Center can confirm who you are and where you are. The other details—such as color and tail number, destination and route, or weather at departure—do not serve as the identification cue in this situation. The callsign plus the squawk code (or ident) is the standard way to establish and verify identity with radar and radio authority.
