Thanks for the good piloting tips!
There should be no difference in the Flight path vector readings, as there can be no difference in the length of the landing gear, half-wing, etc.
The onboard processor on a live aircraft calculates the value of the Flight path vector and provides all consumers. You know that very well. But your CL650 obviously has two sources of calculations and the Flight path vector display, and from here there is a difference (I may be wrong). In my subjective opinion, HUD has more plausible data.
Do you think I have correctly justified the need for amendments, or will we continue the debate on how to pilot an airplane correctly?
