3. Job Set-up
Subtask 27-96-00-860-065-A

A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) Pressurize the Green and Yellow hydraulic systems of the aircraft (Ref. AMM TASK 29-23-00-863-001) (Ref. AMM TASK 29-24-00-863-001).
(3) Make sure that the ADIRS are aligned (Ref. AMM TASK 34-10-00-860-004).
(4) On the overhead panel 23VU:

release the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches (on these pushbutton switches, the OFF legends come on).

(5) On the overhead panel 24VU:

release the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches (on these pushbutton switches, the OFF legends come on).

(6) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(7) On the center pedestal, on the ECAM control panel, push the F/CTL pushbutton switch (on the lower ECAM display unit, the F/CTL page comes into view).

4. Procedure
Subtask 27-96-00-710-053-A

A. Do this test:

ACTION	RESULT
1.On the center pedestal: set the pitch-trim control-wheel to 3 UP.
2.On the overhead panel 24VU: push the FLT CTL/SEC 2 pushbutton switch.	On the overhead panel 24VU: the OFF legend of the FLT CTL/SEC 2 pushbutton switch goes off.
	On the center pedestal: the pitch-trim control-wheel moves slowly to the O position.
	On the lower ECAM display unit, on the F/CTL page : the PITCH TRIM indicator shows 0 DEG plus or minus 0.3

5. Close-up
