Mh ok..thank you for your answer :).
Are there any information about the engine climb seetings around? With Climb Thrust set to 90% and a TOW of 13.000 LBS i reach FL450 within 5 Minutes....i know this bird is a little rocket but this is a bit insane, isn't? And one more question about the IAS Mode: Normally, this mode works in other private jets like FL Change in a Boeing. The autopilot change the pitch of the aircraft to keep a the desired speed. In the GLJ, i have to use the vertical speed mode? Is that correct?
