PARALLEL TRACK (PTK)

NOTE: Enroute/Terminal VNV (baro-VNV) is disabled when parallel track is active. This will cause vertical deviation to flag and the autopilot to uncouple fromVNV. Parallel track disregards all vertical aspects of the flight plan; that is, parallel track ignores baro-VNV.

The Parallel Track (PTK) menu option (Figure 5-127) allows the pilot to create a parallel course offset of 1 to 99 nm to the left or right of the current flight plan (Figure 5-126). Parallel Track cannot be activated if a course is set using Direct-to or if the active leg is the first leg of the departure procedure, or the Initial Approach Fix (IAF) has been passed. Attempting to activate parallel track with these conditions results in the message ‘PARALLEL TRACK UNAVAILABLE INVALID ROUTE GEOMETRY’.
