How should a civil pilot state an aircraft call sign when using the aircraft manufacturer's name?

  1. The manufacturer's name, then the digits and letters, without the N
  2. The prefix N, then the manufacturer's name, then the registration digits only
  3. The registration letters only, with no manufacturer's name
  4. The manufacturer's name, then the prefix N, then the digits only
Show answer

Correct answer: The manufacturer's name, then the digits and letters, without the N

AIM gives the example "Aztec Two Four Six Four Alpha." The N is dropped when the make or model is stated.
