An altitude preselect apparatus for use with or incorporation into an automatic flight control system combines the incremental altitude signal from a pneumatic encoding altimeter with a vertical speed computation to generate a smooth, continuous instantaneous altitude signal. A vertical speed reference signal is generated to control the vertical flight path of the aircraft when the instantaneous altitude reaches a prescribed proximity to a desired flying altitude which is manually selected by the pilot. The apparatus initiates a capture sequence to hold the aircraft at the desired altitude once it is reached.

An apparatus for an automatic flight control system of an aircraft having an altimeter capable of providing signals representative of incremental changes in altitude, said apparatus comprising: means for providing a signal representing vertical speed of said aircraft; first manually operable control means for selecting a desired altitude and for providing a signal representing that altitude; means coupled to receive said incremental altitude signal and said vertical speed signal for producing a signal representing an instantaneous altitude; means coupled to receive said desired altitude signal and said instantaneous altitude signal for providing a preselected vertical speed reference signal to said automatic flight control system to control said vertical speed of said aircraft until a predetermined instantaneous altitude is achieved, whereafter said vertical speed varies in accordance with a prescribed functional relation to altitude differences between said desired altitude and said instanteous altitude.
