When coordinating a departure clearance, what information is sufficient to communicate with the Radar Controller immediately after issuance?

• A. The full flight plan and aircraft type
• B. The airport name only
• C. The airport name and altitude cleared to
• D. The destination airport and speed

Answer: (C)

Focusing on the essentials of initial radar coordination, the controller needs a reference point and a vertical constraint to start monitoring you and ensure safe separation. Saying the airport of departure gives the radar room a definite location to track, and stating the altitude you were cleared to climb to establishes your initial vertical requirement. With that minimal information, the controller can set your initial altitude, monitor your climb, and begin vectoring or routing as needed.

The other details aren’t as critical right after issuance. A full flight plan and aircraft type aren’t needed to establish radar contact or begin the initial separation checks. The airport name alone doesn’t tell the controller what vertical level you’re supposed to reach, and while the destination or speed are important for flight planning and later instructions, they aren’t the primary data needed to start radar coordination immediately.
