Pilots who train with this system can learn to fly blindfolded or to carry out complex maneuvers, such as holding the helicopter in a stationary hover.
The HALS system provided the UH-60 pilots with continuous 3d real-time radar imagery of the landing zone throughout the approach, hover, and landing in complete brownout.
The tests, conducted on a specially instrumented "hover pit, " also validated the performance of aircraft software, controls, thermal management, STOVL-system hardware and other systems.
