Taxiway Routing allows the flight crew to use the touchscreen controller to enter taxi routes, which then provides guidance on the 2D navigational maps or 3D SVT depictions. SurfaceWatch™ runway monitoring technology complements TOLD calculations to provide indications and alerts designed to help prevent pilots from taking off or landing on the wrong runway, a runway that is too short or a taxiway. It also displays the remaining runway distance information on the PFD during the takeoff roll and landing rollout.
