ABSTRACT:
Aircraft display symbology provides quantitative deceleration information in relation to a pilot familiar reference on a HUD system combiner. The symbology displayed includes a deceleration scale composed of a series of marks that provide a known reference for the display of deceleration information. The number of marks on the scale and the positioning and labeling of the marks can be tailored for a particular aircraft type. In a preferred embodiment, the deceleration scale is displayed along and proximal to the vertical path traveled by an aircraft acceleration symbol, which indicates the actual longitudinal acceleration or deceleration of the aircraft. The offset distance of the aircraft acceleration symbol below an aircraft reference or "boresight" symbol shows the actual (inertial) deceleration during landing rollout and rejected takeoff. The position of the aircraft acceleration symbol relative to the deceleration scale marks thereby shows the actual deceleration with respect to the reference provided by the scale. The deceleration scale is preferably displayed only when it is intended to be used--during landing rollout and during a rejected takeoff.
