In that case why do controllers ask "...XXX123, say your requested level"?
Is it not annotated on the flight-plan strip?
Is it not 'Airmanship' to advise an ATC sector as soon as practicable if you request a level differant from the one originally filed for?
And LATCC controllers please note, as drivers we see many differant standards of 'controlling' just as you probably see differing levels of compliance to instructions therefore some 'newie' crews entering the UK FIR for the first time may have differant expectations of the provided ATC services.
A Controller simply saying "Contact **** on ***.** leaves the system open to mis-use.
I think the practice of 'Contact **** on ***.** with heading & speed only', or "Contact Director Callsign only" are excellant proven phrases that could be incorporated more into R/T discipline to reduce frequency congestion...
....as well as FIR boundary-direct-to-FIR boundary given as a matter of course instead of having to tie up the frequency by grovelling....(I jest!)
