Operational Test of the Rudder Artificial-Feel Loads without Tool

TASK 27-23-00-710-001-A-01
Operational Test of the Rudder Artificial-Feel Loads without Tool

WARNING: MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.

WARNING: MAKE SURE THAT THE CONTROLS AGREE WITH THE POSITION OF THE ITEMS THEY OPERATE BEFORE YOU PRESSURIZE A HYDRAULIC SYSTEM. UNWANTED MOVEMENT OF HYDRAULICALLY OPERATED ITEMS CAN CAUSE SERIOUS INJURY AND/OR DAMAGE.

WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.

WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:

THE FLIGHT CONTROLS
THE FLIGHT CONTROL SURFACES
THE LANDING GEAR AND THE RELATED DOORS
COMPONENTS THAT MOVE.

MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.

4. Procedure
Subtask 27-23-00-710-056-A

A. Do this test :

ACTION	RESULT
1.At the CAPT or F/O seat: Push the right pedal until it touches the mechanical stop (variable stop).	The rudder moves smoothly to the right. The force you must apply increases slowly and continuously until the pedal touches the mechanical stop.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator moves smoothly to the right.
2.Slowly release the right pedal and push the left pedal until it touches the mechanical stop (variable stop).	The rudder moves smoothly to the left. The force you must apply to the right pedal decreases slowly and continuously, then becomes zero. The force you must apply to the left pedal increases slowly and continuously until the pedal touches the mechanical stop.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator moves smoothly from the right to the left.
3.Slowly release the left pedal.	The rudder moves to the neutral position. The force you must apply to the left pedal decreases slowly and continuously, then becomes zero.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator goes back to neutral.
4.Engage the autopilot, on the FCU: Push the AP1 (AP 2) pushbutton switch.	The green lines of this pushbutton switch come on.
	NOTE: The solenoid of the artificial feel unit is energized. The second spring of the artificial feel unit is engaged.
5.At the CAPT or F/O seat: Push the right pedal.	the force you must apply to the pedals is multiplied by three at the threshold. at mid travel of the rudder, the AP disengage. the force you must apply decreases suddenly and the pedal goes to the mechanical stop.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator moves to the right.
Release the right pedal.	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator goes back to neutral.
6.Engage the autopilot, on the FCU: Push the AP1 (AP 2) pushbutton switch.	The green lines of this pushbutton switch come on.
7.At the same seat: Push the left pedal.	the force you must apply to the pedals is multiplied by three at the threshold. at mid travel of the rudder, the AP disengage. the force you must apply decreases suddenly and the pedal goes to the mechanical stop.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator moves to the left.
Release the left pedal.	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator goes back to neutral.
8.At the CAPT or F/O seat: Push the right pedal until it touches the mechanical stop (variable stop).	The rudder moves smoothly to the right. The force you must apply increases slowly and continuously until the pedal touches the mechanical stop.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator moves smoothly to the right.
9.Slowly release the right pedal and push the left pedal until it touches the mechanical stop (variable stop).	The rudder moves smoothly to the left. The force you must apply to the right pedal decreases slowly and continuously, then becomes zero. The force you must apply to the left pedal increases slowly and continuously until the pedal touches the mechanical stop.
	On the lower ECAM display unit, on the F/CTL page: the pointer of the RUD indicator moves smoothly from the right to the left.
10.Slowly release the left pedal.	The rudder moves to the neutral position. The force you must apply to the left pedal decreases slowly and continuously, then becomes zero.
	On the lower ECAM display unit, on the F/CTL page : the pointer of the RUD indicator goes back to neutral.

NOTE: If the feel loads are not satisfactory:
