A Commercial Air Transport flight is being operated by Air France, an airline which uses it's name as it's radio call sign, on a Boeing 747 with the registration mark F-JACD. The flight number is 1234. Which of the following is a correct initial full call sign?

  • A

    Air France 34 Heavy

  • B

    747 Jumbo FCD Heavy

  • C

    Air France JACD Heavy

  • D

    747 France FCD

Looking at the answer options:

'Air France 34 Heavy' → INCORRECT. The flight number has been abbreviated.

‘747 Jumbo FCD Heavy' → INCORRECT. You would not say "747 Jumbo".

'Air France JACD Heavy' → CORRECT. The question asks for the correct initial full call sign. A Boeing 747 is in the Heavy wake category. Based on the question details this could be:

  1. The registration marking of the aircraft: F-JACD Heavy
  2. The telephony designator followed by the last 4 characters of the registration: Air France JACD Heavy
  3. The telephony designator followed by the flight Identification: Air France 1234 Heavy

‘747 France FCD’ → INCORRECT. The company call sign is Air France, not just the word 'France'.

TypeExample
a) the characters corresponding to the registration marking of the aircraft;G-ABCD or Cessna G-ABCD
b) the telephony designator of the aircraft operating agency, followed by the last four characters of the registration marking of the aircraft; orFASTAIR DCAB
c) the telephony designator of the aircraft operating agency, followed by the flight identification.FASTAIR 345

For aircraft in the heavy wake turbulence category, the word HEAVY shall be included immediately after the call sign in the initial radiotelephony contact between such aircraft and ATS unit. This is necessary for separation purposes. The same applies to the aircraft in the super heavy turbulence category, with the word SUPER.
