Nose wheel trim sensor
Some B777 pilots are talking about this device wich should allert the crew of a wrongly trimmed B777, ence a wrong loadshet or loading. Can you tell why it did not probably work in that case?
Additionally: having some experience flying commercial A/C, happened to me and very probably to many of you to take off with a tail heavy A/C and not knowing it. This does not mean that I have to hit the tail: even in fly by wire A/C we can feel the rotation speed and check our attitude; especially if we do not have turbolences (like seems to be the case on tha day in ZRH).
