C'mon guys...REALLY?
Who's "benefit" is this for anyway?
Who gives a "toss" "rats ass" or otherwise...
The previous controller says "contact director (here is the clue in case you missed it being pedantic) CALL SIGN ONLY" Which means "CALL SIGN ONLY"
It means forget the atis ID, passing level, "good morning/evening/Merry Xmas etc", your age or otherwise...CALL SIGN ONLY.
Call sign only means just that...CALL SIGN ONLY.
Here is the correct way to contact Dubai Director when told by the previous controller to "contact director..CALL SIGN ONLY..." ....."XX123"...no more no less...if they want more, they'll ask.
If there is more expected then they'll publish it in the CCI, AOI or country specific notes.
Seems very clear to me. The scary thing is that some rocket scientist will post below with some other interpretation of what "CALL SIGN ONLY" means.
