@Lordyaswas,
Quote:For five minutes. Only.
After that the toggle needs to go to lock again to lock it for another five minutes.
The wrong position in an emergency would only lock it for five minutes.
The locking procedure would need to be repeated.
I suppose it might be possible for the Captain to return after say 1min of the descent, the co-pilot bumps the switch the wrong way, then at the 6 minute mark the pilot would gain access, leaving 2 min till impact . With all the banging on the door, the co-pilot would have to ignore it or keep throwing the switch the wrong way...that can happen, but it shouldnt be considered when looking for a cause the first time around .
It doesnt look good for the co-pilot does it ? Thats a scenario that is shocking . I find it difficult to accept for emotional reasons . I have also worked with a lot of pilots . It is hard to imagine a suicide where he would take his plane and passengers with him.
