The control unit may represent, for example, a stationary personal computer or laptop computer.

As explained above, the brake system and the wheel of the aircraft can be controlled by a single pair of pedals mounted in the cabin of the aircraft. To actuate the brakes of the aircraft pedal rotates around the axis of rotation, while the actuation of the rudder of the aircraft are provided by pressing the pedal forward, i.e. towards the front end of the aircraft. Thus, by appropriate selection of the point of application of force to the pedal device according to the invention can be used to test the operation of the brakes of an aircraft or the operation of the steering wheel.

Then rod 24 application of force added to the pedal 12” of the aircraft by means of a suitable clamping device. The point of application of force to the pedal 12, i.e. the point of connection between the thrust 24 application of force to the pedal 12”, choose depending on that, do test the braking system of the aircraft or the steering system of the aircraft. In the case of testing the brake system of an aircraft is the point of application of force to the pedal 12” is chosen so that the actuation device 14 to actuate the pedal caused the rotation of the pedal 12” around the axis T of the rotation. Conversely, in the case of testing the steering system of the aircraft, the point of application of force to the pedal 12” is chosen so that the actuation device 14 to actuate the pedal caused the translational movement of the pedal 12 in the direction of the front end of the aircraft.

For actuation of the pedal 12” aircraft motor 16 of the device 14 to actuate the pedal rotates in such a way as to reduce the length of the worm of the worm gear 20 and thereby cause the lever 18 is transmitted in the forward direction, i.e. in the direction of the pedal 12” aircraft. In the rotary movement of the lever 18 is transmitted driving force ele is tradigital 16 is transmitted to the rod 24 of application of force and, therefore, the pedal 12” aircraft. Motor 16 controls unit 32 of the management in accordance with pre-defined reference parameters, which form the basis of the computer program running in block 32 of the control.

After actuation of the pedal 12” aircraft impact force applied to the pedal 12” electric motor 16 through the worm gear 20, the lever 18 is transmitted and thrust 24 effort, measured by the sensor 26 efforts. The sensor 26 effort signals corresponding to the force applied to the pedal 12”, at block 32, the control signals coming from the sensor 26 efforts to block 32 control, enhanced device 34 signal amplification and regulation of power.

In the case of testing the brake pedal aircraft unit 32 control receives signals from the device 28 measuring the deflection of the pedal, which correspond to the deviation or angle of rotation of the lever 18 is transmitted and, therefore, the angular deviation of the pedal 12” aircraft after application of force feedback to the pedal 12” aircraft. When tested rudder pedals of an aircraft unit 32 control receives signals from the device 30 of measuring the deflection of the steering wheel, which correspond to angular deviation ru is I 13 aircraft after application of force feedback to the pedal 12” aircraft.

Unit 32 of the management processes the signals from the sensor 26 efforts, as well as from the device 28 measuring the deflection of the pedal and the device 30 of measuring the deflection of the steering wheel, respectively, and generates output signals indicating the angular deviation of the pedal 12 and 13 steering of the aircraft, respectively, depending on the efforts of the impact applied to the pedal 12” aircraft. As illustrated in the drawing, the relationship between the force applied to the pedal 12” aircraft, and the angular deviation of the pedal 12 or 13 steering of the aircraft, respectively, the output unit 32 of the control in the form of a diagram showing a graph of the angular deflection of the pedal 12 and 13 steering of the aircraft, respectively, from the efforts of the impact applied to the pedal 12” aircraft. This chart is displayed on the display 38 of the frame 32 of the control, and is printed using a printer that is connected to the block 32 of the control and controlled by this block.

In addition, the block 32, the control compares the measured minimum and maximum values of the angular deviation of the measured minimum and maximum values the efforts of the impact, measured values of coupling and measured values of symmetry with the corresponding nominal values. Unit 32 of the control will emit a warning signal in the IDA messages of a specific color on the display 38 of the frame 32 management if the difference between the measured value and the nominal value exceeds a predefined limit.

In conclusion, the data obtained by the block 32 for the test, and the results of the above comparison values of angular deflection of the pedal 12 and 13 steering of the aircraft, respectively, with two preset values the efforts of the impact with the corresponding nominal values of angular deflection of the two preset values the efforts of the impact is stored in the storage device of the server 40 of the database.
