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.

[ What is claimied is:] [1.] In an aircraft optical display system that produces images for observation by a pilot, the display system including an image source providing an image carried by light propagating along an optical path and an optical display surface positioned so as to provide an image for observation by the pilot, a method of providing for display on the display surface quantitative aircraft deceleration information symbology that alerts the pilot to, and thereby prevents delayed pilot recognition of, possible inadequate deceleration of an aircraft as it moves on the ground, comprising:displaying reference symbology;displaying aircraft acceleration symbology that changes position on the display surface to indicate corresponding changes in actual longitudinal acceleration or deceleration of an aircraft as it moves on the ground, the changing position of the aircraft acceleration symbology causing a corresponding change in a display offset distance between the reference symbology and the aircraft acceleration symbology, the change in display offset distance representing a relative change in acceleration or deceleration of the aircraft; andpresenting an aircraft deceleration display scale on the display surface to provide a reference for display of quantitative deceleration information for the pilot to interpret the actual deceleration of the aircraft.
