Antilock braking system with directional control

A method for correcting a yaw of an aircraft traveling on a runway, the method comprising:

• triggering a computer implemented routine by:
• fully depressing each of a left wheel brake pedal associated with a left hand wheel brake and a right wheel brake pedal associated with a right hand wheel brake;
• and
• deflecting a rudder off-center using a rudder pedal;
• receiving a directional input upon the triggering of the routine;
• imposing by a controller a pulsing cycle wherein an intermittent and automatic release of both of the left and right hand wheel brakes occurs;
• and
• using the routine to reduce a pressure on one of the left hand wheel brake and the right hand wheel brake according to the directional input, wherein the routine artificially increases a calculated ground speed of the aircraft used to compute a slip of one of a left and right wheel, causing the slip of one of the left and right wheels to also artificially increase, thereby inducing an antilock braking system to subsequently reduce the slip of one of the left and right wheels to a target slip by reducing the braking pressure on one of the left hand wheel brake and the right hand wheel brake.

A method for adjusting an unintended yaw of an aircraft having a nose wheel, a left wheel, a right wheel, an antilock braking system, a left brake pedal for operating a left wheel brake associated with the left wheel, a right brake pedal for operating a right wheel brake associated with the right wheel, a controller for executing a computer implemented routine, and a rudder, the method comprising steps:

• triggering the routine by:
• depressing one of a left rudder pedal and a right rudder pedal to cause the rudder to deflect off-center;
• and
• depressing fully the left brake pedal and the right brake pedal to cause the antilock braking system to respectively apply an optimal retarding force with each of the left wheel brake and the right wheel brake;
• receiving by the controller a directional input from the rudder after the routine has been triggered;
• and
• using the routine to deliver a braking output by the controller to automatically reduce an actual braking pressure of one of the left wheel brake and the right wheel brake in line with the directional input until the depressed rudder pedal is released, wherein the routine artificially increases a calculated ground speed of the aircraft used to compute a slip of one of the left and right wheels, causing the slip of one of the left and right wheels to also artificially increase, thereby inducing the antilock braking system to subsequently reduce the slip of one of the left and right wheels to a target slip by reducing the braking pressure on one of the left hand wheel brake and the right hand wheel brake.

A method for adjusting the yaw of an aircraft, the aircraft having a no sewheel, a left wheel, a right wheel, a left wheel brake for applying a retarding force to the left wheel, a right wheel brake for applying a retarding force to the right wheel, a left brake pedal associated with the left wheel brake, a right brake pedal associated with the right wheel brake, a rudder and a rudder pedal associated therewith, and a braking system having a controller and non-transitory memory for implementing a routine, the method comprising steps:

• triggering the routine when each of:
• the left wheel brake is applying a retarding force to the left wheel and the right wheel brake is applying a retarding force to the right wheel;
• and
• the rudder is off center;
• receiving a directional input upon the triggering of the routine;
• imposing by a controller a pulsing cycle wherein an intermittent and automatic release of both of the left and right wheel brakes occurs;
• and
• using the routine to reduce a pressure on one of the left wheel brake and the right wheel brake according to the directional input;
• wherein the routine artificially modifies a calculated ground speed of the aircraft used to compute a slip of one of the left wheel and the right wheel, causing the slip of one of the left and right wheels to also artificially increase, thereby inducing the controller to subsequently reduce the slip of one of the left and right wheels to a target slip by reducing the retarding force being applied by one of the left wheel brake and the right wheel brake.
