A rectangular display that places the target at its center as the radar antenna aims at it. The display shows the range, azimuth, and elevation, unlike the earlier versions of radarscopes. It is suitable for tracking only one target at a time. The tracked target is displayed as a line called a wing spot. The length of a wing spot is inversely proportional to the target range. If there are any aiming errors, the blip is suitably displaced from the center. Also known as a G-scan.
