message/request. Regardless of that, the answer from the tower is positive or
negative. In any case the caller must acknowledge the tower’s answer.
General syntax of a radio call:
Called party (i.e. who is called), Caller (i.e. who calls), message/request, reason,
time needed on the runway.
Note: That part of the message in italic is passed depending on the situation, but may
be omitted as well. The caller always has to advise the TOWER on the reason, why
he needs to proceed on the runway or taxiway. TOWER will give the reason of a
negative answer, if the circumstances permit. Irrespective of getting a reason or not,
caller must comply with TOWER’s instructions.
