- Abstract
Unexpected encounters with degraded visual environments (DVE) pose a serious risk to rotary-wing aircraft. Flight symbology systems have been accordingly developed, which offer a set of symbolic cues meant to replace the pilot's lost visual cues. The premise of this investigation is to prove the existence of a predictable relationship between display scaling and pilot response, and in doing so provide a quantifiable and defendable basis for the tuning process. An experiment is designed in which participants conduct a single-axis precision hover using a pared-down, non-conformal symbology system. During the experiment, three display scalings are varied: the acceleration cue scaling Ka, the velocity cue scaling Kv, and the position cue scaling Kx. A fourth independent variable, Lead, is also considered, which represents the amount of velocity prediction afforded by the accel- eration cue. The response is measured according to the root-mean-square (RMS) of the position error, the control activity, and the Bedford workload ratings.
