rather start a new topic...(I did a search!)
So I am getting a bit confused here. A person takes off controller lets say after passing an arbitary figure of 1800 AGL says ' G-ABCD' cleared to climb FL280' I have been shown unless it was uncontrolled airspace / comms failure CHANGE to 1013 straight away. In JAA land of course. Now speaking with an Emirates driver the other day say there ops in Europe and anywhere for that matter is to change withing 1000ft of TA/TL. Ok so now are we all flying on different pressure settings. One is waiting to reach TA , whi,lst another pilot switches straight away - CAP er 413 I did read this ....
