Abstract:
1. A normalized angle of attack indicating system for use in an aircraft comprising: a display gauge having fixed position markings to indicate a predetermined range of normalized aircraft angle of attack in a normalized display presentation, said predetermined range comprising a zero body angle of attack and a stall angle of attack with respect to said aircraft, said display gauge comprising means for displaying said predetermined range in said normalized display presentation; means for selectively displaying an approach reference band for said aircraft in said normalized display presentation when said fixed position markings correspond to a predetermined percentage of said stall angle of attack; and means for displaying a displayable indicia of body angle of attack for said aircraft simultaneously with said normalized angle of attack for said aircraft on said display gauge for providing a composite simultaneous display of said body angle of attack along with said normalized angle of attack for said aircraft, said body angle of attack being dependent on specific constants for said aircraft.
