How many sources can supply High Pressure (HP) bleed air to the pneumatic system?. 3. 4. 1. 2.

What are some of the users of bleed air in the pneumatic system?. Water system pressurization, hydraulic reservoir pressurization, wing anti-icing system, engines starting systems. Cabin lighting, fuel tank pressurization, cargo hold cooling, lavatory flushing. Passenger seat adjustment, entertainment system power supply, in-flight meals heating. Landing gear retraction, cabin pressurization, navigation system cooling.

What is the purpose of the Bleed Monitoring Computers (BMCs) in the pneumatic system?. Monitoring system pressure and temperature. Controlling the distribution of bleed air. Regulating the airflow to the engines. Activating the overpressure valve.

What happens if one adjacent Bleed Monitoring Computer (BMC) fails?. The other BMC takes over most of its monitoring functions. The entire pneumatic system shuts down. The bleed air supply is redirected to ground carts. The engines automatically shut down.

The pneumatic system supplies air to various A/C systems through a distribution and supply ducting network. True. False.

The Bleed Monitoring Computers (BMCs) are responsible for controlling the airflow to the engines. False. True.

Engine bleed air is regulated both in terms of pressure and temperature before supplying the pneumatic system. True. False.

The APU bleed air supply is only used during flight operations, not on the ground. False. True.

Leak detection elements are installed along the cold air supply ducts of the pneumatic system. True. False.

The crossbleed valve connects or disconnects the LH and RH pneumatic manifolds. True. False.

In each engine pylon, a single detection loop is monitored for leaks by the respective BMC. True. False.

The crossbleed valve connects the LH and RH pneumatic manifolds. True. False.

HP ground connectors supply air through the two HP ground connectors installed at the top right of the belly fairing. False. True.

The APU bleed valve is pneumatically operated. True. False.

The APU BLEED P/B must be set to ON for the BMCs to send an opening command to the ECB. True. False.

Disagreement between the valve position and command triggers an ECAM message. True. False.

What conditions must be met for the APU bleed valve to open?. APU master switch is ON, APU BLEED P/B is ON, No leak detected on APU bleed duct. APU master switch is ON. APU BLEED P/B is ON. No leak detected on APU bleed duct.

What is the function of the crossbleed valve?. Connect or disconnect LH and RH pneumatic manifolds. Monitor APU operation. Regulate cabin pressure. Control APU bleed air flow.

How is the crossbleed valve controlled in automatic mode?. Electrically. Manually. Pneumatically. Automatically.

When is manual control of the crossbleed valve used?. During crossbleed engine start. During normal operation. During automatic control. During APU operation.

How is the leak detection system divided?. Into left and right sub-systems. Into three sub-systems. Into four sub-systems. Into engine and APU subsystems.

Where are the sensing elements located?. Along the bleed air network. In the cockpit. In the cargo hold. Underneath the fuselage.

How many detection loops does each BMC monitor?. Four. One. Five. Three. Two.

What happens if a leak is detected during APU bleed operation?. APU bleed valve closes. Crossbleed valve opens. BMC sends a warning message. Main Engine Start (MES) sequence is initiated.

How are leaks indicated on the AIR panel BLEED P/BSWs?. Amber light. Green light. Red light. Blue light.
