Radar operators in the AC&W squadron tracked the movements of aircraft sighted and passed speed, height and direction information to "Direction Centres" (DC's) and fighter interceptor squadrons. Fighter aircraft were airborne in minutes after an alarm was given, and closed in on unidentified planes by means of radar detection equipment in the fighters. Another of their functions was furnishing navigational aid to friendly aircraft operating in the area. Their detection of "May-Day" calls contributed to quick search and rescue efforts.
