3 letter code, starting with Q

used previously in wireless telegraphy Morse code but still used in voice transmission today

Question 2

How are Q Codes spoken

Answer 2

by letters
not phonetically

Question 3

List the Q codes

Answer 3

QFE
QNH
QNE
QFF
QDM
QDR
QUJ
QTE

Question 4

QDM and QDR

Answer 4

QDM- Magnetic bearing from AC to GS (if there is wind, the wind correction angle has to be applied to the QDM)

QDR - Magnetic bearing from GS to AC

Question 5

QUJ and QTE

Answer 5

QUJ- True bearing from AC to GS

QTE - True bearing from GS to AC

Question 6

QFE

Answer 6

QFE-
altemeter pressure setting or airfield daturn (runway threshold or highest point in the airfield)

denoting the “height” of aircraft from airfield datum

QFE=zero if aircraft is on the airfield ground

Question 7

QNE

Answer 7

QNE-
standard setting of 1013.2 hpa for flight levels about transition altitude

Question 8

QFF

Answer 8

QFF-
QFE reduced to MSL using actual temperature

It’s can be considered as QNH at sea level regardless of the temp

Question 9

QNH

Answer 9

QNH-
altemeter pressure setting or airfield reduced to AMSL value

denoting the “altitude” of aircraft from sea level

QFE-
altemeter pressure setting or airfield daturn (runway threshold or highest point in the airfield)

denoting the “height” of aircraft from airfield datum

QNH of aircraft on airfiled = Elevation of airfield from sea level
