So, let's say you're flying North and concerned with rigidity and errors while banking left or right... as far as the inner case, you shouldn't think of it as banking left or right, but rather banking West or East, because it's gonna (mostly) stay fixed in space.
If you start a right turn, the "cabin gravity" banks East (referencing the up direction of it, not down) and starts accumulating a slight bit of that error. Well, as you come through 180 degrees of turn headed South and stay in the right bank, the Cabin G is now banked West and the continued error accumulation cancels the East-banked error accumulated in the first 180 degrees. So every continued half-circle of a turn accumulates an error that cancels the previously accumulated error.
At least as far as I understand it... maybe I'll learn some more that causes me to reverse position once again!
Yes But..... Over some time the pendulous vanes will get the idea that the centrifugal force resulting from the centripetal force generated by the wing is actually gravity and so the gyro will align itself with the resultant of this and gravity will they not? Might take some time to happen but Icant see any other result
