1. General. Self-announce is a procedure
whereby pilots broadcast their position or intended
flight activity or ground operation on the designated
CTAF. This procedure is used primarily at airports
which do not have an FSS on the airport. The
self-announce procedure should also be used if a pilot
is unable to communicate with the FSS on the
designated CTAF. Pilots stating, “Traffic in the area,
please advise” is not a recognized Self−Announce
Position and/or Intention phrase and should not be
used under any condition.
