Could someone clarify why in the Major UK airports most of the UK based drivers when calling for startup after clearance 99% say something along the lines of “Callsign 123, PDC received, fully ready etc etc”.
I’m being very pedantic here, but after a decade of this, it’s got to me. Firstly why state PDC received? ATC already know that by reading back clearance or confirming via ACARS. Is it SOP?
Secondly (and this I really don’t understand). Why call “Fully ready”? You are either ready or you’re not ready. You cannot be partially ready. I’ve noticed the same call is made frequently to Tower Frequencies.
Discuss!
Oh and Happy New Year and Bah Humbug!
