AUTO VLOC TUNING †
Auto-VLOC tuning is a user option which enables the automatic
tuning of the active nav frequency slot to follow the governing
navaid in the flight plan.
If the active leg is part of a VHF-based approach, the FMS will
auto-tune the navaid that defines the final approach.
If the active leg is not part of a VHF-based approach, and if the
active leg has a recommended navaid in the nav database, the
FMS will auto-tune that navaid. Otherwise, from the active leg,
the FMS will look backward through the route and forward
through the route for legs with a recommended navaid or that are
defined by a navaid, in which case, the FMS auto-tunes the one
of those two navaids that is closer to the aircraft.
