ABSTRACT:
A method modifying the landing pitch attitude of an airplane during landing approach and touchdown is disclosed. A reference value for a predetermined flight condition parameter is subtracted from a current value of the predetermined flight condition parameter, resulting in a difference value. Based upon the difference value, a schedule determines a corresponding deflection value for a movable surface capable of producing lift. The movable surface is automatically deflected to an amount equal to the deflection value. In alternative embodiments of the invention, the predetermined flight condition parameters include approach airspeed, attitude, and angle of attack.
