B. Operational Test of the Ground Spoiler Extension

ACTION	RESULT
1.On the center pedestal: move the throttle control levers to the idle position. preselect the speed brake control lever.
2.On the ECAM control panel on the center pedestal: push the F/CTL key.	On the lower ECAM display unit, the F/CTL page comes into view.
3.On the driving tool: set a wheel speed of approximately 1000 rpm.	On the lower ECAM display unit, the spoilers 1, 2 and 5 extend.
NOTE: In you find a problem, do a BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001) and record the maintenance message.
4.On the center pedestal: move the throttle control levers to the climb position.	On the lower ECAM display unit, the spoilers 1, 2 and 5 go to the neutral position.
5.Remove the 355M03190000 MLG WHEEL TACHOMETER DRIVING TOOL355M03190001 WHEEL TACHYMETER DRIVING TOOL, MLGG5-5M0-319-0000 MLG WHEEL TACHYMETER DRIVING TOOL from the wheels 1 and 4 and install it on the wheels 2 and 3.
6.Do steps 1 to 4 again for the wheels 2 and 3.	Same result as steps 1 to 4 with the spoilers 3 and 4.
