Cockpit engine and system controls, switches
Carrying on from enthusiastic discussion, we'll have this thread as a repository for cockpit engine and systems controls, including switches. This is not an accident discussion thread. Nor is it a thread to discuss pilot deliberate action which was undesired. This is a "how does it operate?", "why was it designed that way?", and what thoughts do we have about how it could be better and more safe?
Discussion on locks and guards which prevent unintended operation are welcome, and thoughts on more advanced systems which prevent unintended operation/misuse/or cascading failure are welcome. I'll be back along later with thoughts I have about this, because in part, I certify these controls as a part of my work in aircraft certification. I'm really thinking about how it should work well, and what can be done to prevent it being hazard prone.
