A runway indicator is displayed overlying a target runway for providing supplementary guidance to support the pilot's ability to fly a stabilized approach. The highlighted runway position indicator provides cues to verify that the aircraft is continuously in a position to complete a normal landing using normal maneuvering during the instrument segment of an approach and includes a landing threshold, a landing zone on the runway, an approach line leading to the runway, an outline highlighting the sides and ends of the runway, a rectangle larger than and surrounding the runway, and a visual precision path approach indicator.
