Sleeve, If you fly on QFE, you get a height clearance, not an altitude clearance. Or so I was taught. It sounds very picky but if you get it wrong the consequences can be severe.
QFE -> height
QNH -> altitude
QNE -> flight level
I've never done a MATZ transition because I don't fly in the UK (often). Does theory here indeed match practice? In other words, do the MATZ controllers use "height" consistently when talking QFE? And do pilots get this correct too?
