A. Do this test
WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS ARE
_______ CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE.
CAUTION : MAKE SURE YOU DO NOT CAUSE AN ACCIDENTAL DISCHARGE OF THE
_______ ENGINE FIRE EXTINGUISHERS. THE ENGINE FIRE EXTINGUISHERS ARE ARMED DURING THE TEST.
CAUTION : DO NOT START OR DRY MOTOR THE ENGINES WITH A HYDRAULIC GROUND
_______ POWER SUPPLY CONNECTED TO THE AIRCRAFT. IF YOU DO, YOU CAN CAUSE DAMAGE TO THE ENGINE PUMPS.
NOTE : This procedure as written is for the valve 1046GK, differences in
____ the procedure for the valve 3046GD are shown in brackets.
NOTE : On the glareshield panels 130VU and 131VU:
____
-reset the MASTER CAUT lights before you do the subsequent procedure.
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1.
Dry motor the left (right) engine The left (right) engine turns and
(Ref. TASK 71-00-00-710-001). causes the engine pump of the Green (Yellow) hydraulic system to turn. The ECAM lower display unit (DU) shows the pressure in the Green (Yellow) hydraulic system is 3000 psi approximately.
2.
Operate the sidestick and rudder
pedals so that the control
surfaces move continuously.
3.
On the ECAM Lower DU:
-------------------------------------------------------------------------------
ACTION RESULT -------------------------------------------------------------------------------
-monitor and make a note of the Green (Yellow) hydraulic fluid level.
4. On the ENG/APU FIRE panel 1WD of the overhead panel 20VU:
-lift the guard and push and release the ENG 1 FIRE (ENG 2 FIRE) P/BSW.
-continue to operate the side stick and the rudder pedals
NOTE : The noise that you can
____ hear comes from the engine driven pump and is normal
