QFE operational questions
[1] In areas that utilize QFE (I'm not sure where that is besides Russia, China ?) is the Transition Altitude always the same as the Transition Level, and if not, how often is it different?
[2] Have you ever had a problem obtaining a QNH altimeter setting from the controlling authority?
[3] Does your aircraft have direct measures to accommodate operating in a QFE environment, or do you need to use more manual methods?
[4] Is the altitude input to your EGPWS from GPS or from barometric altitude?
