Abstract:

A pilot factors evaluation of the Harowe Altitude Warning System was conducted 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, Decision Height mode, was incorporated in the AWS to examine the concept of altitude warning during landing approaches. Ten sorties were flown in a North American T-39 Sabreliner. Pilots were selected from the IFC and Instrument Pilot Instructor School student population. The normal mode of operation was found acceptable for aiding pilots in leveling at and maintaining desired altitudes. The accuracy of the normal mode was acceptable and with further development of the Decision Height Mode, the Harowe system would be acceptable for installation in Air Force aircraft.
