Accumulator and Reservoirs
System 3 has an accumulator that stores nominal hydraulic pressure to satisfy
instantaneous demands of aircraft systems and dampen pressure surges within the
system. The accumulator is precharged with nitrogen to 1500 psi.
System 3 reservoir is the largest of the three hydraulic systems with a capacity of 11.14
liters (2.94 U.S. Gal.). It is filled via the ground service panel located in the right main
wheel well.
During preflight, a visual inspection should include a check for accumulator pressure
at 1500 psi. With the exception of the accumulator gauge, system 3 components are
not readily accessible with the wheel well bins installed.

Controls and Indicators
The HYDRAULIC Panel provides the system controls; the EICAS Hydraulic
Synoptic Page provides a pictorial representation of the system status, and the EICAS
Primary and Status pages provide the system caution and advisory messages
respectively (see Figures 13-7 to 13-9 and Table 13-1).

: With generators 1 and 2 off, hydraulic
pump 3B is load shed when AUTO is selected.
(See System 3 schematic, fig. 13-5)
: Whenever the ADG is deployed and
supplying electrical power to the aircraft, hydraulic
pump 3B will automatically operate regardless of
switch position. (See System 3 schematic, fig. 13-5)
