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
