If an approach leg is active, the status indicates that the system is unable to activate theparallel track with the message ‘Parallel Track Unavailable Approach Leg Active’. If the offset direction and distanceresults in an unreasonable route geometry (e.g., there is a sharp turn of more than 120 degrees), the status indicatesthat the system is unable to activate the parallel track because of invalid geometry (‘Parallel Track UnavailableInvalid Route Geometry’). If the active leg is not a track between two fixes (TF) or a course to a fix (DF) leg, the statusindicates that the system is unable to activate the parallel track because parallel track is not available for theactive leg type (‘Parallel Track Unavailable Not Allowed for Active Leg’). Parallel track is also unavailable for aleg if there are no legs remaining in the flight plan after the given leg, or OBS mode is activeParallel track will be cancelled if the active leg changes to a leg where one of the preceding is true.Activation of parallel track will apply from the current position along the flight plan until a leg that does notmeet the criteria for parallel track. Guidance will be computed to return to the original track at the beginningof that leg.Cancelling parallel track:1) Press the FPL Key to display the Active Flight Plan Page (MFD) or the Active Flight Plan Window (PFD).2) Press the MENU Key, highlight ‘Parallel Track’, and press the ENT Key.
