D. Preparation for the Test
(1)
Pressurize the reservoir of the Yellow hydraulic system (Ref. TASK 29-14-00-614-002).
(2)
Make sure that the fluid level in the reservoir of the Yellow hydraulic system is correct. Add fluid as necessary (Ref. TASK 12-12-29-611-001).
(3)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(4)
Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).
(5)
On the ECAM control panel on the center pedestal, push the HYD pushbutton. Make sure that the HYD page on the system (lower) display comes on.
