I've been wondering why most of the LH crews start their reply with their callsign:
Example:
ATC: "LH 123 climb FL 310..."
Pilot: "LH 123 climbing FL310 etc..."
I hear most airlines ending their reply with their callsign. I'm not sure what the ICAO standard is but always thought it is more easier this way. Callsign first is ATC, instruction first is the pilot.
Any ideas <img src="confused.gif" border="0">
