This transition normally occurs within 2.0 nm of the final approach fix (FAF). The CDI switches to approach scaling automatically once the approach procedure is activated or if Vector-to-Final (VTF) is selected. - If the active waypoint is the FAF, the ground track and the bearing to the FAF must be within 45° of the final approach segment course. - If the active waypoint is part of the missed approach procedure, the active leg and preceding missed approach legs must be aligned with the final approach segment course and the aircraft must not have passed the turn initiation point. 190-01263-01 Rev.
