A method and apparatus for reducing the unwanted sideways motion of an airplane by reducing the lateral side loads and upsets caused by atmospheric turbulence and gusts is disclosed. A rudder modification command that causes the rudder command of the airplane to be changed in a manner that relieves the net force across the vertical stabilizer of the airplane caused by atmospheric turbulence and gusts is produced. More specifically, the pressure differential across opposite sides of the vertical stabilizer is measured and used to produce a rudder deflecti...
A method of producing a rudder modification command for reducing unwanted sideways motion in the aft cabin of an airplane comprising: determining the pressure differential across the opposite sides of the vertical stabilizer of the airplane; producing an airmass sideslip angle value based on said pressure differential; roll and yaw compensating said airmass sideslip angle value to produce a compensated airmass sideslip angle value; high-pass filtering said compensated airmass sideslip angle value with a filter having a corner frequency that is approximat...
