Regarding the discussion about whether or not to use the aircraft N-number when self-announcing at a non-towered airport (Unicom, February 2021), the most definitive answer would probably be the current issue of the Aeronautical Information Manual (AIM). Aviation Safety is correct in asserting that Advisory Circulars are advisory in nature. The AIM is as well unless the information is incorporated into a regulation by reference. However, Bob Hartmaier is (almost) correct, also. In Section 4-1-9, in Recommended Self Announce Procedures (6). the AIM states: “Report approximately 10 miles from the airport, reporting altitude, and state your aircraft type, aircraft identification, location relative to the airport….”
Bob suggests that if there were an accident or incident somehow associated with failing to use the recommended phraseology, an explanation would be required to the FAA. Actually, the explanation would probably have to be made to an NTSB Administrative Law Judge (ALJ) adjudicating a violation action brought by the FAA. We can’t be violated for failing to comply with advisory information; however, if that advisory information is tied to a regulatory violation, it could be used to support that charge.
