TASK 27-23-00-710-001-A
Operational Test of the Rudder Artificial-Feel Loads with Tool (355M03200001)

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.

4. Procedure
Subtask 27-23-00-710-050-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.Energize the solenoid 16CA with the 355M03200001 TOOL-28 VDC POWER SUPPLY.	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 until it touches the mechanical stop (variable stop).	The rudder moves smoothly to the right. The force you must apply to the pedals is much larger : it is multiplied by three at the threshold. it is multiplied by two at the limit of the travel.
	On the lower ECAM display unit, on the F/CTL page : the pointer of the RUD indicator moves smoothly to the right.
6.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 is much larger: it is multiplied by three at the threshold. it is multiplied by two at the limit of the travel.
	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.
7.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.
8.De-energize the solenoid 16CA with the 355M03200001 TOOL-28 VDC POWER SUPPLY.	NOTE: The solenoid of the artificial feel unit is de-energized. The second spring of the artificial feel unit is disengaged.
9.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.
10.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.
11.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.
