When contacting ATC for the first time, which identification should you use for GA versus airline?

• A. The aircraft type and color.
• B. The aircraft's callsign as filed (N-number for GA, airline designator plus flight number for airlines).
• C. Pilot's license number only.
• D. Flight plan ID only.

Answer: (D)

When you first contact ATC, you identify yourself with the aircraft’s callsign as filed. For general aviation, that callsign is the N-number (the registration). For airline operations, it’s the airline designator plus the flight number. This unique identifier lets ATC know exactly which aircraft you are and keep track of your route, altitude, and instructions as you enter their airspace. Using color or aircraft type isn’t a reliable identifier, and a pilot’s license number isn’t used for radio communication as the means of identifying your flight. The flight plan ID is an internal reference, not the voice identifier you use in the initial radio call. So you should say the callsign as filed when you reach out to ATC.
