  • All-axis control of aircraft in ultra deep stall
    Patent number: 4261533
    Abstract: Tilting the stabilizer at an extreme angle to the fuselage, with leading edge down, and controlling and varying engine thrust comprise a method for all-axis control of a generally conventional aircraft in ultra deep stall. The method is effective in recovery from unstable and unusual flight attributes and in landing emergencies; the aircraft may land in the ultra deep stall configuration or conventional flight may be resumed. So-called flying wing aircraft, where pitch control surfaces are incorporated with the trailing edge of the primary lift surface, are also controllable in ultra deep stall by the method of this invention.
