Kiltie has implied that I answered Stinker99's original question below incorrectly. (I can't see any thread drift here.)
'On initial contact with London control in a climb/descent is the correct phraseology
C/S passing level cleared level
or
C/S cleared level only'
On the first call to London, after dep from STN, and having reported the passing level to STN DIR, there is no requirement to report the passing level again unless requested. That is correct, is it not?
''AD 2-EGLL-6-1 London Heathrow Compton 3F SID Note 4
Callsign for RTF frequency used when instructed after take-off 'London Control'. Report callsign, SID designator, current altitude and cleared altitude on first contact with 'London Control'. ''
PR's example above is at LL where London happens to be the 1st radar unit you call anyway, so this is not a very useful example.
