1. The idea of "say aircraft type to Radar" Why ???? Doesn't the controller have this information ? We are just blocking the freq which is already busy.
3. Why insisting on pilot to say SID, altitude passing, altitude cleared to ?
4. Why saying QNH.... after you have said information X received ?
1. Mistakes can be made on flight plans so we need to make sure that you are the correct type of aircraft shown on the flight strip in front of us. What we don't want is getting less than the required vortex spacing required or you being parked on a stand that you can't use
3. We need to know the passing altitude so as make sure that you Mode C data is accurate. The SID needs to be confirmed to make sure you go the right way and the cleared altitude needs to be confirmed to make sure you don't bust the clearance and end up hitting something coming the other way.
4. because the QNH can change before the new information is transmitted.
