3. Job Set-up
Subtask 27-54-00-941-063-A

A. Safety Precautions
(1) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
(2) Put the WARNING NOTICE(S) in position to tell persons that the flap and slat systems are in operation.

Subtask 27-54-00-860-067-A

B. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) Pressurization of the hydraulic systems

NOTE: Make sure that the hydraulic pressure is sufficient to move the flaps and slats.

(a) Pressurize the Yellow hydraulic system
(Ref. AMM TASK 29-10-00-863-002) or (Ref. AMM TASK 29-24-00-863-001).
(b) Pressurize the Blue hydraulic system
(Ref. AMM TASK 29-10-00-863-003).
(c) Pressurize the Green hydraulic system
(Ref. AMM TASK 29-10-00-863-001) or (Ref. AMM TASK 29-23-00-863-001).

4. Procedure
Subtask 27-54-00-710-051-A

A. Operational Test

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.

(1) Do the Electronic Instrument System (EIS) start procedure (Ref. AMM TASK 31-60-00-860-001).
(2) Do this test:

ACTION	RESULT
1.On the center pedestal on the panel 114VU:	On the aircraft:
move the slat and flap control lever to position 1 and then to position 2. Stop at both notches until the flaps and slats are in their new position.	the flaps and slats move to their set positions. On the ECAM upper DU: the flap and slat position bars move to their set positions the new position of the control lever and the travel direction of the flaps and slats are shown.
2.On the panel 114VU: move the slat and flap control lever to the position 3.	On the aircraft: the flaps move to the set position the slats do not move. On the ECAM upper DU: the flap position bar moves to the set position the slat position bar does not move the new position of the control lever and the travel direction of the flaps are shown.
3.On the panel 114VU: move the slat and flap control lever to the position FULL.	On the aircraft: the flaps and slats move to their set positions. On the ECAM upper DU: the flap and slat position bars move to their set positions the new position of the control lever and the travel direction of the flaps and slats are shown.
4.On the panel 114VU: move the slat and flap control lever back to the position 3.	On the aircraft: the flaps and slats move to their set positions. On the ECAM upper DU: the flap and slat position bars move to their set positions the new position of the control lever and the travel direction of the flaps and slats are shown.
5.On the panel 114VU: move the slat and flap control lever back to the position 2.	On the aircraft: the flaps move to the set position the slats do not move. On the ECAM upper DU: the flap position bar moves to the set position the slat position bar does not move the new position of the control lever and the travel direction of the flaps are shown.
6.On the panel 114VU: move the slat and flap control lever back to the positions 1 and 0. Stop at both notches until the flaps and slats are in their new position.	On the aircraft: the flaps and slats move to their set positions. On the ECAM upper DU: the flap and slat position bars move to their set positions the new position of the control lever and the travel direction of the flaps and slats are shown no warnings related to the flap and slat systems are shown.
