COM 4.1 ALPHA – NUMERIC CALLSIGNS

The concept of call sign confusion and particularly the use of alphanumeric call signs are investigated by IFATCA.


IFATCA Policy is:

To reduce the possibility of call sign confusion:

  • Call signs that correspond to the last two designators of both ICAO and/or IATA airport designators of either the point of origin or destination of the flight, shall not be used.
  • In alphanumeric call signs, aircraft operator designators shall not be chosen that will create confusion with phonetic letters.
  • The use of tools that reduce possible call sign similarity shall be encouraged.
