This all plays into how easy it is - or is not - to use, especially while seated in either seat.
It is a frequent subject in accident investigation - where are XXXX and could the person get it, or make a mistake hitting it, etc.
I don't know what you mean by "concierge engineering" — this is an airplane, not a hotel.
However, the video addresses your questions.
One interesting point is, the video claims the control module can optionally be mounted in the ceiling instead of the center console. Putting it overhead would obviously preclude an unconscious pilot from randomly hitting the Lock switch with his elbow or something.
Concierge engineering, ergonomics, etc. To make things easier to use. But hopefully still fool-proof.
But they are almost never fool-proof.
I watched the video now.
The default location doesn’t give me great confidence. Neither does the fact this is a bounce-back switch always going to the midway position.
I also find it curious that the access code can override the lock? If only for 30 seconds. Did I miss something? Maybe it is still in Norm; must leave, don’t have time to rerun video now. Later.
