QFE - is the barometric altimeter setting that causes an altimeter to read zero when at the reference datum of a particular airfield (in practice, the reference datum is either an airfield center or a runway threshold). In ISA temperature conditions the altimeter will read the height above the airfield/runway in the vicinity of the airfield.
The altimeter setting used is the ISA sea level pressure of 1013 hPa or 29.92 inHg. The actual surface pressure will vary from this at different locations and times. Therefore, by using a standard pressure setting, every aircraft has the same altimeter setting, and vertical clearance can be maintained during cruise flight. [1]
During conditions of exceptionally low atmospheric pressure it is not possible to set QFE or QNH on some aircraft altimeters. In these circumstances an aerodrome or runway QNE can be requested. The QNE is the reading in feet on an altimeter with the sub-scale set to 1013.2 hPa when the aircraft is at aerodrome or touchdown elevation. [2] QNH
QFF is the location value plotted on surface synoptic chart and is closer to reality than QNH, though it is only indirectly used in aviation. [citation needed] Another method [which?]: The derivation assumes that an isothermal layer at the station temperature extends to the sea level.
QFE : What should I set on the subscale of my altimeter so that the instrument would indicate its height above the reference elevation being used? If you set the subscale of your altimeter to read ____ millibars, the instrument would indicate its height above aerodrome elevation (above threshold, runway number ____). QFF
The Mets won the Soto battle, but when it comes to success in 2025, the Yankees have set themselves up to win the war. 5. The NL Central will have three 85-win teams.
