QNE - Q Code - Doc 8400 ICAO
 

Hi,

I've been looking for the exact definition of QNE lately and I was surprised to observe that you cannot find anything about QNE in the following ICAO document:

PANS - ICAO abbreviations and codes (doc ICAO 8400 - 20 november 2008) : http://dcaa.slv.dk:8000/icaodocs/Doc%208400/

Does anybody know what happened to QNE. Has it been eliminated from the Q code list for real ?

Thank you very much for your help.

There is a popular misconception that QNE refers to a pressure setting (1013.2HPa) in the same way as QFE and QNH - this is, of course, incorrect. QNE refers to the reading on an altimeter on landing when the standard pressure setting is set and is therefore measured in feet and not hectopascals. QNE has, to the best of my knowledge, never appeared in ICAO Doc 8400 and neither has the equally useful QEO (I have cleared the runway)

QNE
 

It is still mentioned in the CAA CAP 413 radiotelephony manual in the index in chapter 1, page 8:

The definition is like Billiebob said. I heard someone say a while ago that it is used on some high elevation airports in the world. Does anyone know how exactly? Would be interesting.:hmm:

Wikipedia also has the wrong definition of QNE, but they mention QSY and QFU. I think only the last one may appear in some official publications, but not in the UK I think.

regards,
