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.
- QTE = True bearing from the station to the aircraft.
Therefore, two calculations should be done:
1. Converting the bearing to the station from Magnetic (QDM) into True (QUJ), applying the Variation:
- QUJ = QDM - VAR = 248° - 10° = 238° (Variation West, Magnetic Best)
2. Converting the True bearing To the station into True bearing From the station:
- QTE = QUJ - 180° = 238° - 180° = 058°.
