Download Human Engineering Laboratory Helicopter Acquisition Test Helhat books, The U.S. Army Human Engineering Laboratory conducted a series of flight tests in 1972 (HELHAT I) and 1973 (HELHAT II) in which the low-level target acquisition performances of combat-trained OH-58 and AH-1 helicopter crewmen were measured. The stationary targets used were both ordnance and high-visibility box-type targets. This study contains all of the data gathered during these tests and also reports on the 25 performance variables measured for each of the 851 recorded target acquisitions. These variables were used to form the linear equations which were analyzed by the use of a step-wise multiple-regression technique in order to identify the variables contributing to stationary target acquisition performance. There were 831 acquisitions recorded during the low-level route reconnaissance flights flown at above the ground levels of 80 to approximately 400 feet and 20 acquisitions recorded during the six nap-of-the-earth 's' search reconnaissance flights flown at above the ground levels of 1 to approximately 40 feet.
