The Research and Development Division, USAF Instrument Flight Center (USAFIFC/RD) conducted a pilot factors evaluation of the Harowe Altitude Warning Signal System (AWSS) to determine its acceptability for use in Air Force aircraft. The system has the primary function of assisting pilots in attaining and maintaining assigned or desired (command) altitudes. A secondary function, the approach mode, was incorporated in the AWSS to examine the concept of altitude warning during landing approaches. Thirteen sorties were flown in an NT-38 Talon. Subject pilots were selected from IFC personnel. The overall concept and operation was found to be acceptable by half of the subject pilots. Half of the subject pilots felt the information provided by the system did not justify the increased workload. The normal and approach modes of operation were found to be acceptable in concept, operation, and accuracy. The system in its present configuration is not acceptable for installation in trainer and single place aircraft due to the unacceptable increase in cockpit workload. (Author)
