The RASCAL JUH-60A is a research and technology demonstrator aircraft developed by the U.S. Army and NASA as an airborne laboratory.
RASCAL stands for Rotorcraft Aircrew Systems Concepts Airborne Laboratory. The base platform is a UH-60A. The aircraft has been used in investigations of advanced, integrated control concepts for achieving high levels of agility and maneuverability, and guidance technologies, employing computer/sensor-aiding, designed to assist the pilot during low-altitude flight in conditions of limited visibility.
