I thank you very much. I shall do what you ask me to morrow, if you permit that.
leave me tell you what it follows: I have just do twice the same take off from Roissy, engines working, plane at the end of the track. All is adjusted: direction, altitude and speed. FD and A/T arm are on. Only AP is not armed. I take off and sometime after, I put on the AP. All is correct. and go on well. These take off are executed with 747-8
Then after, I take the plane at one door. Engines stopped. I carry out all operations to start as for the two previous flights.
I take off with the same settings, speed, altitude and direction. At the same time as the two other departures, I put on the AP and there, nothing append, the plane doesn’t turn.
I don’t understand at all.
