[Not a pilot] Should there have been an anticipation that the backup system would fail too?. My understanding from previous posts is that this double-failure is unique to the type and perhaps unique for all aircraft with electrically-operated backup landing gear systems.
Re: circuit breakers. (Sorry for using household terms.) The only way that I can conceive of inadvertently popping a breaker (based on the photograph only) is by hooking the "button" with the strap of a bag. Is there another way?
Also, I recognize that there is a wide variety of breaker types, but would someone please explain how many positions the "button" could be in? The most I can conceive of would be:
- Pushed in and connected
- Pushed in but internally disconnected
- Popped out a bit and disconnected
- Pulled out all the way and disconnected
- Intermediate (say from being bent or sticky) and either connected or disconnected
- [just thought of:] held pushed in by a bag or something and either connected or disconnected
Thank you.
