Jazz 7777
 

Does this call sign drive any of you controllers crazy ? ,,,And of course the pilots probably more so, who have to transmit it for ~1-3 hours or more.

What do all of these words have in common :

one, two, three, four, five, six, eight, nine, ten

What is different about 'sev-en' ? .... duh ?

Why weren't any of them used instead of sev-en.

"Lunatics running the asylum" ? :ugh:

Whose "bright idea" was this?

Jazz Quadruple Seven.

Cuts out two syllables.

That helps, but why use the number 7? .. at least not exclusively for the first digit / prefix ?

And why use a 4 digit callsign ? .. I doubt they have 999 different flights ?

I would have thought that the "powers that be" of call signs would take brevity of R.T. into consideration when approving a new company's call signs?

With Jazz, the number of numbers (hee-hee) seems to change with the seasons.......:ugh:

You forget niner (correct phraseology). There is a THA999 operating in this part of the world which I think must drive the Thai pilots/ATC crazy...

Interesting point.

I'm not sure what the ATC manuals /procedures are .. or even if they are the same worldwide, but I've never hear ATC use "niner" for callsigns. They do of course use it for alt / spd / hdg / alitmeter.

Have you heard the pilots / ATC use "niner" to identify those flights ?

I have heard both flying in Australia...

... In Australia group form is the preferred form of transmitting callsigns (paraphrased from AU AIP GEN 3.4-20 para 4.16.1). As examples are listed Sunstate 122 as "Sunstate One Twenty Two", and Car 21 as "Car Twenty One".

There are no examples in the AIP of callsigns involving 9, however I can recall hearing all of Thai Niner Niner Niner, Thai Nine Nine Nine, and Thai Nine Ninety Nine when on frequency.

Maybe an Australian ATC can elaborate what is more correct? I guess the main thing is that the message gets across...
