Track Made Good (TMG)

The track made good (TMG) is the actual path travelled by an aircraft over the ground, which may differ from the planned track due to the effects of wind drift or steering inaccuracies. Comparing the planned track to the TMG allows a pilot to calculate track error.

Key Points

  • •Represents the real path achieved over the ground, as opposed to the intended planned track.
  • •Used in conjunction with the planned track to calculate track error (TE).
  • •Essential for applying proportional navigation techniques such as the 1 in 60 rule.

Exam Relevance

Calculating TMG is essential for assessing drift, establishing position lines, and making accurate off-track corrections in flight.
