System and method for controlling traveling direction of aircraft
First Claim
1. A system for controlling traveling direction of an aircraft that is installed with a plurality of landing gear on right and left sides of its airframe, wherein a larger braking force is applied to landing gear wheels on a side toward which the control stick is operated than a braking force acting on landing gear wheels on the other side, in the case of a control stick being operated toward the right or left side directions of the airframe.

Abstract
The present invention is structured such that, as for travelling on the ground, there is provided a braking mechanism capable of braking wheels by the use of a single brake pedal or a braking mechanism capable of braking the wheels by flare out operation of a control stick, while automatic control of traveling direction is performed in flight using a yaw damper. In addition, a larger braking force is automatically generated, without manual operations by a pilot, for landing gear mounted on the side of an airframe toward which direction of an aircraft is to be changed as compared with the braking force applied to landing gear on the other side.

16. A method of controlling traveling direction of an aircraft that is installed with a plurality of landing gear on the right and left sides of its airframe, comprising the steps of:
-
detecting a direction of operation and an amount of operation of a control stick which is performed by a pilot in a direction to the right or left side of the airframe;
detecting the speed of the aircraft; and
determining whether or not the speed of the aircraft is equal to or less than a predetermined value, wherein the method further comprises the steps of;
determining the side, when the speed of the aircraft is less than or equal to the predetermined value, to which the direction of travel of the aircraft is to be changed, based on the direction of operation of the control stick, computing an amount of brake operation based on the amount of operation of the control stick; and
supplying the computed amount of braking to landing gear wheels mounted on the side of the airframe to which the direction of travel is to be changed. - View Dependent Claims (17, 18, 21, 22)

19. A method of controlling a direction of travel of an aircraft that is installed with a plurality of landing gear on the right and left sides of its airframe, the method comprising steps of:
-
detecting a direction and an amount of operation of a control stick performed by a pilot in a direction to the right or left side of the airframe;
detecting the speed of the aircraft;
detecting that braking operations have been performed by the pilot; and
determining whether or not the speed of the aircraft is equal to or less than a predetermined value, wherein the method further comprises the steps of;
determining, based on the direction of operation of the control stick, to which side of the aircraft the direction of travel is to be changed, when the speed of the aircraft is less than or equal to the predetermined value and it is determined that the braking operation have been performed;
computing an amount of braking pressure reduction based on the amount of operation of the control stick for cases in which braking operation has been performed; and
supplying the computed amount of braking pressure reduction to landing gear wheels mounted on the side of the airframe that is opposite to the side to which the direction of travel is to be changed. - View Dependent Claims (20)
