Specific Information Items
1.
Aircraft Identification (Item 7) Aircraft Identification is always required. Aircraft identification must not
exceed seven alphanumeric characters and be either:
(a)
The ICAO designator for the aircraft operating agency, followed by the flight identification (for
example, KLM511, NGA213, JTR25). When in radiotelephony the call sign to be used by the aircraft will consist
of the ICAO telephony designator for the operating agency followed by the flight identification (for example,
KLM511, NIGERIA213, JESTER25);
(b)
The nationality or common mark and registration of the aircraft (for example, EIAKO, 4XBCD,
N2567GA), when:
(1)
In radiotelephony, the call sign to be used by the aircraft will consist of this identification alone
(for example, CGAJS) or preceded by the ICAO telephony designator for the aircraft operating agency (for
example, BLIZZARD CGAJS); or
(2)
The aircraft is not equipped with radio.
NOTE
−
1.
Standards for nationality, common and registration marks to be used are contained in Annex 7, Chapter 2.
2.
Provisions for using radiotelephony call signs are contained in Annex 10, Volume II, Chapter 5. ICAO designators and
telephony designators for aircraft operating agencies are contained in Doc 8585—Designators for Aircraft Operating
Agencies, Aeronautical Authorities and Services.
NOTE
−
Some countries’ aircraft identifications begin with a number, which cannot be processed by U.S. ATC automation. The
FAA will add a leading letter temporarily to gain automation acceptance for aircraft identifications that begin with a
numeral. For flight
−
processing systems (e.g., ERAM or STARS) which will not accept a call sign that begins with a
number, if the call sign is 6 characters or less, add a Q at the beginning of the call sign. If the call sign is 7 charac-
ters, delete the first character and replace it with a Q. Put the original call sign in the remarks section of the flight
plan.
EXAMPLE
−
9HRA becomes Q9HRA
5744233 becomes Q744233

Flight Rules (Item 8a)
