What is a flight call sign & What is a tactical call sign?

CALL SIGN :

An aircraft call sign is a group of alphanumeric characters used to identify an aircraft in air-ground communications.

The rules governing the use of aircraft call signs are laid down in ICAO Annex 10: Aeronautical Communications, Volume II – Communication Procedures, Chapter 5. Relevant paragraphs are summarised below.

3 different types of aircraft call sign

  • TYPE a
  • TYPE b
  • TYPE c
Call signs may be abbreviated only in the manner shown below (see table).Type (a) The first character of the registration and at least the last two characters of the full call sign (the name of the aircraft manufacturer or model may be used in place of the first character);Type (b) The telephony designator of the aircraft operating agency, followed by at least the last two characters of the call sign; Type (c) No abbreviated form.

Most airline call signs belong to type (c) for which there is no abbreviation. Therefore, abbreviations such as “1234” or “Rushair 34” are not permissible. An aircraft is not permitted to change its call sign during flight, except temporarily on the instruction of an air traffic control unit in the interests of safety.

Tactical call sign :

call sign that identifies a tactical command or tactical  (military)communication facility.Military call signs are call signs assigned as unique identifiers to military communications. In wartime, monitoring an adversary’s communications can be a valuable form of intelligence. Consistent call signs can aid in this monitoring, so in wartime, military units often employ tactical call signs and sometimes change them at regular intervals. In peacetime, some military stations will use fixed call signs in the international series.

The United States Army uses tactical designators that change daily. They normally consist of letter-number-letter prefixes identifying a unit, followed by a number-number suffix identifying the role of the person using the callsign.
