QFE on a slope runway?
I am just wondering that on such a slope runway while taking off, which position does the QFE read '0' when you are on it?(the highest point on the runway(AAL) or its departure end elevation?)
Since I have been thru so many people done the settings regarding the acceleration altitudes which someones use an altitude + a departure end elevation and others use + AAL.
Could someone please clarify this? and I would really appreciate a true reference link for it.
