Q-codes

Note: the letters in the Q-code nomenclature have no literal significance,
these are remnants of an extensive notation system from the days of
wireless-telegraphy. There were some 200 three letter Q-codes each
representing a sentence, a phrase or a question, for instance QRM "I am
being interfered with"!. Some 30 Q-codes are still used by amateur radio /
morse code enthusiasts and the four below, plus QDM (the magnetic bearing
to a station), still survive in aviation. For a full listing of Q-codes try

QNE: is the ISA Standard Pressure altimeter setting of 1013.2 hPa. The term
QNE is now rarely encountered but if you set 1013.2 on the altimeter
pressure-setting scale while parked the altimeter will indicate the current
ISA pressure altitude of the airfield - which is the first step in
calculating density altitude. QNE is also the standard factory setting for
altitude encoding.
