Procedure Track

This HEAVY line/arrow indicates the Approach Path or Procedure Track inbound to the airfield. It contains a Heading value in the middle of the arrow. In this example, 279 Course is given as the Procedure Track for the approach.

Notice it is the Heavy line pointing to the airfield. The track is the 099 Radial of GVO and you must fly a course of 279 to maintain this approach path. This line can contain turns, arcs, and descents as you can see in the Profile View.
