Just wondering if anyone had come across some pitch limitations for the whiskey compass on a 744. I'm assuming the ball is sitting on a pivot... and at certain pitch angles the ball is going to hit the glass or rear of the container. (Note: I'm not talking about magnetic field lines being at an angle at the poles).
Perhaps someone has one in a workshop... or sitting on a desk as a paperweight?
Thanks.
Rgds.
