The APS-3000 Autopilot System is another step in the evolution of digital automatic flight control systems at Rockwell Collins. Designed to take full advantage of the benefits of the Pro Line 21 integrated avionics system, the APS-3000 is an integrated autopilot and flight director system providing dual independent flight directors and a three-axis fail-passive autopilot with automatic pitch trim control signals. The Rockwell Collins APS-3000 is highly flexible and can be tailored to meet the airplane's mission with relative ease.
