13 / 20

Given:

QDM: 138°
VAR: 10°E

The QUJ equals...

  • A

    318°.

  • B

    168°.

  • C

    328°.

  • D

    148°.

Refer to figure.
For this type of questions, the comprehension of some basic definitions is required:

  • Variation is the difference between true and magnetic heading or between true and magnetic track. Remember the rhyme: Variation East(+), Magnetic Least - Variation West(-), Magnetic Best.
  • QDM = Magnetic bearing from the aircraft to the station.
  • QUJ = True bearing from the aircraft to the station.

Therefore, only one calculation should be done, converting the bearing to the station from Magnetic into True, just applying the Variation:

  • QUJ = QDM + VAR = 138° + 10° = 148° (Variation East, Magnetic Least)
