Sec.  87.107  Station identification.



    (a) Aircraft station. Identify by one of the following means:

    (1) Aircraft radio station call sign.

    (2) Assigned FCC control number (assigned to ultralight aircraft).

    (3) The type of aircraft followed by the characters of the 

registration marking (``N'' number) of the aircraft, omitting the prefix 

letter ``N''. When communication is initiated by a ground station, an 

aircraft station may use the type of aircraft followed by the last three 

characters of the registration marking.

    (4) The FAA assigned radiotelephony designator of the aircraft 

operating organization followed by the flight identification number.

    (5) An aircraft identification approved by the FAA for use by 

aircraft stations participating in an organized flying activity of short 

duration.

    (b) Land and fixed stations. Identify by means of radio station call 

sign, its location, its assigned FAA identifier, the name of the city 

area or airport which it serves, or any additional identification 

required. An aeronautical enroute station which is part of a 

multistation network may also be identified by the location of its 

control point.

    (c) Survival craft station. Identify by transmitting a reference to 

its parent aircraft. No identification is required when distress signals 

are transmitted automatically. Transmissions other than distress or 

emergency signals,

such as equipment testing or adjustment, must be identified by the call 

sign or by the registration marking of the parent aircraft followed by a 

single digit other than 0 or 1.

    (d) Exempted station. The following types of stations are exempted 

from the use of a call sign: Airborne weather radar, radio altimeter, 

air traffic control transponder, distance measuring equipment, collision 

avoidance equipment, racon, radio relay, radionavigation land test 

station (MTF), and automatically controlled aeronautical enroute 

stations.
