Don't want QNH on first contact with LHR approach.
C/S, type, atis letter and cleared level is all, thanks
If we don't get type or cleared level we have to come back and ask you for it.
You'll obviously get the QNH on first descent out of a flight level.
p.s. and please give callsign only only when instructed to do so...not on first contact with approach on handover to 119.725 or 134.975 as then we have to come back and ask you for everything.
