Its the same procedures for QFE and QNH, its just the datum that has changed.
Couldn't agree more so for the purposes of simplicity why not stick to one datum? The argument for making ccts easier because you're flying 'round' numbers is nonsense really, if you can't add a thousand feet or whatever the cct height is to an airfield elevation then maybe it's time to hang up the flying gloves. Apart from which and not really connected to the issue of QFE but any aviator worth their salt should know what a thousand feet looks like without an altimeter. Has the ability to fly a perfectly good circuit anywhere without an altimeter been lost?
