All terrain ground collision avoidance and maneuvering terrain following for automated low level night attack

The development of an all-terrain ground collision avoidance system (GCAS) in conjunction with a maneuvering terrain-following (TF) system is discussed. Both systems use a digital terrain database. These systems are presented concurrently because of their complementary mission role. The unprecedented pilot interaction available with the automatic systems provides a means to improve combat survivability significantly. The pilot is able to execute high rate turns, evasive maneuvers, and inverted ridge crossings while following the terrain contour. Safety is maintained in day, night and weather by the GCAS. The combination of these systems with an automated attack system, automatic target handoff system, night vision system, and a route planner to provide a lethal night attack capability is examined. Piloted simulation and preliminary flight test results are presented.<>
