Some questions though for those of you flying the CJ2 - why do you climb in IAS not Mach at high altitude? That seems just to be making it harder. Would I be correct in thinking that very little of the type or recurrent training is done at high altitude?
It uses Collins Proline, so the display will transition from KTS to Mach automatically at altitude.
As for training, for certification a simulator need have no fidelity above 20,000' so it is correct to say that little or no training for all types occurs at high altitude.
