The Modular Integrated Display and Sight Helmet (MiDASH) is designed to meet utility, reconnaissance, and attack helicopter mission requirements. It provides twenty-four hours day and night head out flight, Nap-Of-The-Earth (NOE) capability. The system includes observation system and weapons system cueing in an integrated comfortable helmet. The MiDASH offers wide field of view (WFOV), see-through, binocular night imagery, flight information and LOS (Line Of Sight) cueing for day and night operations. The system provides aircraft flight data as well as warning & threats information, allowing the pilot to fly head out during the entire mission, day and night. This relieves the pilot from the need to switch between outside and cockpit scan. The system thus decreases pilot workload while enhancing mission effectiveness, situational awareness, and safety of flight. The MiDASH test and evaluation program included lab tests, human factors tests and flight tests. The paper presents the MiDASH system and discusses the flight test and evaluation program. It details the goals, success criteria, and methods. The paper also addresses flight training, and details the main findings and observations.
