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