Abstract
An aircraft is provided with a mechanical linkage that mechanically transmits an amount of manipulation of a control stick to a rudder controlling mechanism, an amount-of-manipulation sensor that detects the amount of manipulation, and an FBW control-law computing unit that calculates an FBW control-law command indicating an amount of control for a craft in accordance with the detected amount of manipulation. Also, with the aircraft, a high-pass filter outputs, among the control-stick manipulation amounts detected by the amount-of-manipulation sensor, an amount of change in the control-stick manipulation amounts; by subtracting the amount of change that has passed through the high-pass filter by means of the subtracting portion, the FBW control-law command serves as an SAS command; and the rudder controlling mechanism is driven by adding an amount of movement of an SAS actuator in accordance with the SAS command to the control-stick manipulation amount transmitted by the mechanical linkage.

4. An aircraft comprising:
-
a control stick for a pilot to maneuver a craft; an amount-of-rudder-control transmitting part that mechanically transmits an amount of manipulation of the control stick to a rudder controlling part; a detecting part that detects the amount of manipulation; an amount-of-control calculating part that calculates an amount of control for the craft in accordance with the amount of manipulation detected by the detecting part; an amount-of-change outputting part that outputs, among the amounts of manipulation detected by the detecting part, an amount of change in the amounts of manipulation; a subtracting part that subtracts the amount of change output from the amount-of-change outputting part from the amount of control calculated by the amount-of-control calculating part; and an actuator that adds an amount of manipulation in accordance with a subtracted value output from the subtracting part to the amount of manipulation transmitted by the amount-of-rudder-control transmitting part. - View Dependent Claims (5)

6. An aircraft control method which is a method of controlling an aircraft provided with a control stick for a pilot to maneuver a craft, an amount-of-rudder-control transmitting part that mechanically transmits an amount of manipulation of the control stick to a rudder controlling part, a detecting part that detects the amount of manipulation, an amount-of-control calculating part that calculates an amount of control for the craft in accordance with the amount of manipulation detected by the detecting part, the aircraft control method comprising:
-
a first step of outputting, among the amounts of manipulation detected by the detecting part, an amount of change in the amounts of manipulation; a second step of subtracting the amount of change from the amount of control calculated by the amount-of-control calculating part; and a third step of driving the rudder controlling part by adding an amount of movement of the actuator in accordance with a subtracted value obtained by the subtraction performed in the second step to the amount of manipulation transmitted by the amount-of-rudder-control transmitting part.
