SESK: Stuff Everyone Should Know · sesk.info/pilot-class-c-two-way-radio

Approaching Class C, the controller replies with your call sign and 'standby.' May you enter?

Yes. Hearing your call sign means two-way communication is established.

  1. Yes, communication is established ✔
  2. No, you need an explicit clearance
  3. No, you must squawk 7600 first

Why: Class C entry needs two-way radio communication, not a clearance. If the controller uses your call sign, even with 'standby,' you may enter. Without your call sign, communication is not established.

Huh, didn't know that: Class D works the same way: a reply using your call sign, even with 'standby,' means you may enter.
