QFE makes perfect sense to my simple little brain and I use it all the time when bimbling around in the local area.
When you're on the ground, your altimeter says zero. What could be simpler than that?
My only problem with the ATSIN was the original wording, which initially implied that it would be mandatory for ATCOs to pass QFE
AND Elevation if the setting was requested by the pilot, thereby increasing RT load and the potential for confusion. Pedantic, I know, but symptomatic of how the relevance of our National guidelines has been gradually eroded in respect of GA and operations outside CAS. A few emails later, the wording was changed.
Before I get flamed by the members of Bogota Flying Club and everyone else who thinks QFE is the work of satan, I do think it remains useful in some parts of UK airspace and its use is still prevalent amongst a fair chunk of the industry. Maybe I should join the Flat Earth Society, I bet they use QFE
