Given the following information and the indication shown on the fixed card ADF, what is the true bearing from the station to the aircraft?

Magnetic Variation: 3°W
Compass Deviation: 5°W

  • A

    207°

  • B

    027°

  • C

    117°

  • D

    217°

EASA LO 062.02.02.02.04: Calculate the true bearing from the compass heading and relative bearing.


Refer to figure.
The fixed card ADF has, as the same suggests, a fixed compass card. That is, it will always show "North" up. As such, it provides us with a relative bearing to the station. The question asks us about the true bearing from the station to the aircraft. So we should first convert our compass heading to a true heading, by applying variation and deviation. We can apply the memory aids:

  • Deviation West, Compass Best
  • Variation West, Magnetic Best

Reading the compass heading from the annex as 125°C:

  • 125°C - 5°W deviation = 120°M
  • 120°M - 3°W variation = 117°T

A QUJ is the code for the true bearing towards a station, whereas the QTE is the true bearing from the station, or the reciprocal of the QUJ. The relative bearing is read from the ADF, and is 270°, or we can also consider it to be -90°.

True Heading + Relative bearing = QUJ
QTE = QUJ +/- 180°

QUJ = 117 - 90 = 027°T
QTE = 027 + 180 = 207°T

So, the true heading from the station to the aircraft is 207°T.
