Simulator Evaluation of Five Counter-Pointer Altimeters,
Abstract
An experimental comparison of five counter-pointer altimeters was conducted in the DC-10 cockpit simulator. The altimeters were: (a) 5 digits, snap action counter turnover; (b) 5 digits, analog counter turnover; (c) 5 digits, snap action for the hundreds counter and higher, analog for less than a hundred values. A hold 80, hold 00 feature (during ascent and descent, respectively) was added to eliminate display ambiguity; (d) 3 digits, snap action turnover with barber pole striping in the 4th and 5th digits locations, to aid trend and rate determination; and (e) 3 digits, snap action turnover. Altimeter B proved inoperative and was replaced by an instrument with a modified analog turnover. Ten airline and test pilots served as subjects. A pilot evaluated every altimeter twice by flying each through a standardized 31-minute flight profile. (Author Modified Abstract)
