Caber, you bring me some light when you talked that reversion occurs when HDG SEL / VNAV is selected. Do you know how offset from the track it must be to happen this reversion?
Regarding the verticel offset, the question is the same: how higher about the path the plane must be to revert?
And the last question: have you seen any information about this matter in any official boeing publication?
Once again, thanks a lot.
