Q CODE ALTIMETER SETTING & RADIO NAV

Question 1

Atmospheric pressure at a specified datum such as airfield
runway threshold. When set, the altimeter reads the height
above the specified datum.

Answer 1

QFE

Question 2

Atmospheric pressure at a place, reduced to MSL using the
actual temperature at the time of observation as the mean
temperature.

Answer 2

QFF

Question 3

Atmospheric pressure at sea level in the International
Standard Atmosphere (ISA), equal to 1013.25 mbar or hPa
and used as reference for measuring the pressure altitude.
When flight levels are used as an indication of altitude,
1013.25 hPa is used as mean sea level (QNH).

Answer 3

QNE

Question 4

Atmospheric pressure at mean sea level (may be either a
local, measured pressure or a regional forecast pressure
(RPS)). When set on the altimeter it reads altitude.

Answer 4

QNH

Question 5

Magnetic heading to a station

Answer 5

QDM

Question 6

Answer 6

QDL

Question 7

Answer 11

QTE

Question 12

Position in relation to a point of reference or
in latitude and longitude

Answer 12

QTF
