[QUOTE=Miles Magister;11180591] After 45 years of aviating in both environments my vote is for QFE. /QUOTE]
What is the highest airport at which you have operated using QFE? I often fly between airports with an elevation difference of over 5,000 ft. Even if the altimeter could be set for QFE at both airports it would take a long time to change the baro setting, a distraction I don't need.
I think the only time I have seen QFE used in USA is at low elevation gliding sites where the flights were expected to be local. I hated it and always changed to QFE when I flew.
MD-11 (also MD-10 and 717) PFD was designed for very easy switching between QFE and QNH with both baro setting being retained in memory. Don't remember if that was standard or a customer option.
