We test the hypothesis that experienced airline pilots base their flare timing on the visual cue d_theta/d_t, which can be described as ‘the speed of the apparent runway widening’ or ‘the rotational speed of the runway sidelines’, in contrast to the ‘fixed altitude’ and ‘time to contact (t)’ hypotheses. We analysed data from 57 landings flown by 5 professional airline pilots in level D certified full flight simulators of Boeing 767-type aircraft to get a better understanding of what the pilot is actually looking at. We focus on the availability and use of visual cues by analysing time histories of aircraft states, visual cues, the pilot’s control inputs, and eye-mark recordings of 30 of these landings. We present a statistical analysis of the flare initiation points and a qualitative analysis of the eye-mark data. We conclude that experienced pilots initiate their flares at higher altitudes than the recommended 30 ft (9m) and clearly depending on the sinkrate, thereby rejecting the fixed altitude hypothesis. The eye-mark recordings give much insight in the pilot’s visual cue and instrument use, and suggest pilots use d_theta/d_t rather than time-to-contact to decide their flare initiation.
