Description
Engine bleed air is extracted from the 7th, 10th and 14th stages of the engine compressor, and used by the airplane systems below:
.
7th stage: Pressurization of oil seals, and the venting of engine sumps in the lubrication system.
.
10th stage: Pneumatic supply to the air conditioning and pressurization systems, and engine starting.
.
14th stage: Pneumatic supply to the engine cowl and wing anti-ice systems, or thrust reverser systems.
Components and Operation
Ducting and check valves are used to direct the flow of bleed air from the engine to the 10th-and 14th-stage bleed air manifolds. The nacelle and pylon ducts are monitored for bleed air leakage by the engine fire and jet pipe overheat detection systems.
For additional information, refer to Chapter 9, Fire Protection, and Chapter 18, Pneumatic System.

ENGINE STARTING SYSTEM
Description
The starting system consists of the starter control valve and the air turbine starter. The air turbine
starter drives the accessory gearbox, which in turn drives the N2 core section. DC electrical power and air from the 10th-stage bleed air manifold are required to open the starter control valve and engage the air turbine starter.

The 10th-stage bleed air manifold can pressurized by the:
.
APU;
.
External air cart; or
. 10th-stage bleed air from the operating engine (crossbleed). The following minimum bleed air pressures should be available for an engine start:
.
APU – 40 psi;
.
External air start cart – 45 psi; or
.
Engine crossbleed – 60 psi (approximately 85% N2).
L (R) 10th-stage bleed air manifold pressure is displayed on the SUMMARY page.
During an engine crossbleed air start, ensure that intake and exhaust areas of the operating engine are secure. When starting engines in close quarters, consideration should be given to the effects of jet blast.

Components and Operation
Starter Control Valve
The starter control valve is mounted next to the air turbine starter, inside the engine nacelle. It controls the initial rate of engine acceleration upon engagement of the starter, by regulating the amount of air supplied to the starter. The starter control valve is controlled by the START and STOP switches on the START/IGNITION panel.
