Abstract : A pilot factors evaluation of an altitude warning system (AWS) to determine its acceptability for use in Air Force aircraft. The system has the primary function of assisting pilots in attaining and was conducted maintaining assigned of desired (command) altitudes. A secondary function was to examine the concept of altitude warning during landing approaches. Eleven AWS sorties were flown in a Northrup T-38 Talon, and 33 sorties in a North American T-39 Sabreliner. The majority of pilots considered that an altitude warning devise served as a viable altitude reminder and warning system, reducing the possibility of altimeter misinterpretation. Although several deficiencies were found, the major problem associated with the AWS is the inaccuracy of the trigger levels. (Modified author abstract)
