I don't normally make harsh comment on prune as I don't believe it helps anyone involved BUT on this instance I make an exception.
Maybe he failed you because you were just a bit s
T and that almighty
up seems like as good excuse as any!
Couple of points.
If you had the incorrect mb set on both altimeters, which are going to be in different positions, that kind of rules out parallax. You probably busted your MDA to.
I would imagine you were passable but just needed a bit of extra work and if you busted the mda due to having the incorrect pressure set and cross checked on the main and stby altimeter, that's a big mistake to miss and defiantly a just fail! The examiner with more experience and much more mental capacity was probably sat there checking the altimeters out from all angles for quite sometime while watching you sweat bouncing around the hold as I'm sure he has heard of parallax error.
Just chill and moven on.
Taking legal action against the CAA, grow up!
