Title and Subtitle: Aural glide slope cues: Their effect on pilot performance during in-flight simulated ILS instrument approaches

Report Date: May 1971

Authors: Hasbrook AH, Rasmussen PG

Abstract: Forty instrument rated commercial and ATR pilots with 250 to 12,271 flight hours each flew ten simulated ILS approaches in a single engine, general aviation aircraft. Divided into five groups, each group used a different glide slope cue display in combination with a modified 'T' instrument panel configuration. Two types of aural glide slope cue displays were utilized: voice, and Morse code signals.
