A simplified display system was fitted to the AN/APS-4 to produce the "AN/APS-6", also known as the "AIA-1". The new display, which was only about 5 centimeters (2 inches) in diameter, effectively made the AN/APS-6 a "radar gunsight", allowing a fighter pilot to use the radar himself without need for a radar operator. The pilot wore red-tinted goggles to allow him to retain his night vision. The APS-6 was simple to operate (only six knobs), had a range of five miles, and weighed 250 pounds. It featured a double-dot system that displayed a shadow blip to the right of the true blip; this secondary blip showed the target's altitude relative to the aircraft.
