CONT MOD 09 - APU, Aircraft Pneumatic Systems, Aircraft Pneumatic Anti-Icing and De-Icing Systems, and Aircraft Fuel Systems

There are two fuel pumps installed in each wing.

It is installed to connect or isolate the left and right hand sides of the fuel system.

The fuel system feeds the APU from what tank?

It is a self-contained unit which enables the aircraft to be independent of external pneumatic and electric power.

Where is the APU located in the Airbus A320?

MODIFIED TRUE OR FALSE: The APU operation is controlled by the EMB in the AIrbus A320.

It is open when the APU MASTER SW is selected on, and closes when it is selected off.

On an Aircraft Pneumatic System, the bleed air is used for five main purposes; TICK THE BOXES that selects these five:

What does EBA stand for?

What does FOB stand for?

What does FMU mean?

What does ASM mean?

What does OBIGGS mean?

This is a pressure regulator that is used to maintain a constant level of pressure and regulates engine bleed air supply.

In the situation where the LP stage supplies the pneumatic system, there is a ____________________ to protect the engine against backflow.

The temperature in the pneumatic system must not exceed acceptable values

A fan air is used to allow more or less air to pass the pre-cooler

It is used to cool the engine bleed air temperature down

The crossbleed duct is usually located at the fuselage and connects the left wing pneumatic ducts

An air to air type heat exchanger is used as a cooler

There is an indirect relationship between the LP check valve and HP valve

The leak detection for airbus monitors the areas: pylon ducts, pneumatic wing ducts, fuselage ducts, and APU ducts.

The leak detection for boeing monitors the areas: pylon ducts, pneumatic wing ducts, fuselage ducts, and APU ducts.

The ECB automatically shuts down the APU in case of fault (low acceleration)

The bleed valve is normally a _________________ type valve and pneumatically operated

The temperature regulator system consist primarily of a fan air valve and _____________________.

A type of valve that closes if the HP stage pressure exceeds at a pre-determined value.

It is also known as an APU Bleed Load Valve and is controlled by a switch in the cockpit.

If there is no aircraft pneumatic supply available, this supply can be connected.

Each engine feeds the left or right duct, and they are linked together by a _______________________.

An air duct connects the right and left air systems, this is known as a cross over duct or cross bleed manifold.
