MAJOR COMPONENTS

The airplane pressurization system consists of

the following major components:

• Cabin pressurization control panel

• Cabin pressure controller (CPC)

• Pressurization indicators

• Primary outflow valve

• Secondary outflow valve

• Vacuum jet pump

PRESSURIZATION

CONTROL PANEL

The pressurization control panel and the ECS

system schematic on the EICAS or MFD pro-

vides the crew-to-system interface capability

for all modes of system operation and moni-

toring (Figure 12-1).

PACK SWITCH

The PACK switch (Figure 12-1), located on

the left side of the pressurization control

panel, is used to control the pack bilevel pres-

sure regulating shutoff valve (PRSOV). When

selected on, engine bleed-air is allowed to

enter the environmental control unit (ECU). 

Should the pack bilevel PRSOV not open, due

to a malfunction, the only other method to

provide a source of engine bleed-air for cabin

pressurization is via the emergency pressur-

ization system.
