Can you explain why the plane keeps descending despite being set at 3000 and continues descending to a lower altitude even though the approach button is not activated? How is that possible? And another question, how can they deactivate the autopilot and the autothrottle without touching the buttons?
Approach mode is engaged at 0:25 and then disengaged at 1:34 Altitude hold mode is not engaged which is why the aircraft can descend below the set altitude. As for the autopilot/throttles, there is a disconnect button on the side of the throttles for the autothrottle, and another button on the yoke that disengages the autopilot, sort of like a hotkey.
@@conorcorrigan765Now I have another question, why did they disable the approach button? Isn't it supposed to make the plane continue descending despite having a set altitude? In this case, you had set an altitude of 3000, but it kept descending instead of stopping at that altitude, which is 3000 feet. Also, how do they deactivate the approach button without touching it? Can they also do it from somewhere else?
@@canexfex5325 It was disabled as the pilots were performing a manual visual approach and had the runway in sight. At that point only the FDs stay on. And yes, APP mode can be disconnected by retuning the VHF NAV receiver.
@@conorcorrigan765 but I didn't see if they or if it was you who was on the plane, descend with V/speed after the approach button was deactivated, so how did the plane continue descending if you had set the altitude to 3000 feet, because as I mentioned before, I understood that the approach button took care of that, while it is activated it makes the plane descend even if it had set an altitude, that's why these doubts arose, and I hope you can help me solve them.
@@canexfex5325 If neither APP mode, V/S mode or ALT hold mode are engaged, pitch can be controlled manually, as it was here. The A/P is only engaged at that point in order to provide FD guidance for the approach.
