Thanks for this
Some further questions, if I may
So when descending, if atc say descend from fl30 to 20 would you just change the altitude selector to 20 and the aircraft would do the rest? Or do you need to set a vertical speed?
If you were to fly manually, would you just lower the speed? Would you have to point the nose down or do you hold the nose level and the plane will just descend ?
It's great to talk to a real pilot
