Upon aircraft landing approach, flare path command signals of altitude, vertical velocity and vertical acceleration are generated as functions of aircraft position and velocity with respect to the ground. The command signals are compared with corresponding actual values to generate error signals which are used to control the flight path.

Apparatus for generating flare path control signals for an aircraft comprising: ground position means for producing a ground position signal, Dc; (b) a vertical velocity command signal, hc; and (c) a vertical acceleration command signal, hc, whereby said hc command signal defines the desired flare path of the aircraft and said hc and hc command signals represent desired sink rate and vertical acceleration respectively, corresponding to said desired flare path; sensor means for producing signals h, h and h representative of the aircraft\s actual altitude relative to the runway, vertical velocity and vertical acceleration, respectively; subtracting means for subtracting each actual aircraft signal h, h and h from the corresponding commanded value hc, hc and hc to produce error signals heeeeee
