Direct-To Confirmation
Determining Offpath or OnPath
When the direct-to identifier is selected by scrolling through the
flight plan, the direct-to will always be considered onpath.
Otherwise, the FMS looks through the flight plan starting with the
active leg and continuing downpath for a leg with a matching
identifier. Note that legs in a missed approach are considered
only if the missed approach is enabled. If a matching leg is
found, then the direct-to is considered onpath. If no matching leg
is found, then the direct-to is considered offpath. Note that
because only legs downpath of the active leg are considered,
entering the identifier of a leg
before the active leg will cause the
direct-to to be offpath.
