An aircraft flies a compass heading of 235°(C) to correct for an 8° drift to the right. The variation is 12°W and the deviation is 2°E. What is the aircraft's true track?

  • A
    225° T
  • B

    233° T

  • C
    243° T
  • D
    245° T

Deviation EAST Compass LEAST

Variation WEST Magnetic BEST

M = 235° + 2° = 237°
T = 237° - 12° = 225°

This may potentially be one of the answers, however we have the true heading, not the track - we have not accounted for the drift.

Drift = 8°R
Drift right = Add the drift for track

  • Therefore, 225° + 8° = 233° (True track)
