Pneumatic System

Supplies high pressure air for:

• air conditioning;
• wing anti-icing (not when the source is the APU);
• water pressurisation;
• hydraulic reservoir pressurisation; and
• engine starting.

The sources are:

• engine bleed system;
• APU; and
• 2 external ground units.

Control is done through 2 BMCs, 1 for each engine bleed system.

Note that the APU bleed has priority over engine bleed (engine bleed valves will be closed by their BMC).
