ATA 36 A320 NIVEL AVIANCA

What are the primary purposes of the pneumatic system on the Airbus A320?. Air conditioning and engine start. Fuel Tank Inerting System and pressurization. Anti-icing and ground power unit supply. All of the above.

When can high-pressure air be supplied to the pneumatic system from external ground sources?. Only during engine start. Only during anti-icing procedures. Both on the ground and in flight. Never.

Which engine compressor stages supply bleed air to the pneumatic system?. Only HP stage. Only IP stage. Both IP and HP stages. Neither IP nor HP stage.

What is the purpose of the High-Pressure Bleed Valve (HPV)?. To maintain high pressure in the pneumatic system. To supply air when engines are at low power. To regulate the temperature of the bleed air. To monitor system pressure.

Where is the Pressure Regulating Valve (PRV) installed in the pneumatic system?. Upstream of the IP bleed valve. Downstream of the HP bleed valve. Downstream of the IP and HP bleed valves. Upstream of the High Pressure Bleed Valve (HPV).

Which components of the pneumatic system are primarily installed on the engines and in the pylons?. Pressure regulation components. Temperature regulation components. Leak detection components. Crossbleed valve components.

What happens if one Bleed Monitoring Computer (BMC) fails?. The associated FAULT light is lost. The associated bleed valve closes automatically. The overpressure warning is activated. Both BMCs exchange data via ARINC bus.

The temperature of the engine bleed air is regulated by passing it through an air-to-air heat exchanger called the ________________. precooler. fan discharge. crossbleed. APU supply.

Both Bleed Monitoring Computers (BMCs) receive signals from the leak detection loops. They exchange data via an ARINC bus for wing double loop detection. The wing loops A are connected to BMC 1, and wing loops B are connected to BMC 2. The crosstalk bus allows wing leak warnings to be activated through an ________________. OR logic. XOR logic. AND logic. NOT logic.

How is the engine air bleed pressure pneumatically regulated in the Airbus A320 family of aircraft?. High Pressure (HP) Valve (VLV), Pressure Regulating Valve (PRV). Bleed Monitoring Computers (BMCs), Wing Anti-Ice (WAI). Pressure Regulating Valve (PRV), High Pressure (HP) Valve (VLV). Wing Anti-Ice (WAI), Bleed Monitoring Computers (BMCs).

When does the HP VLV pneumatically regulate the air supply, and within what pressure range does it operate?. At low engine speed, 8 to 36 psi. At high engine speed, 44 to 85 psi. At idle, 110 to 240 psi. At high altitude, 15,000 ft to 35,000 ft.

What is the primary function of the IP check valve, and when does it come into play?. Protects the IP stage from reverse flow when HP VLV is open. Regulates the pressure downstream from the PRV. Monitors engine fire at 450°C. Controls bleed pressure at high altitude.

Describe the two operating modes of the PRV control solenoid and the conditions under which each is used. Pneumatic mode for reverse flow protection, electrical mode for ENGine BLEED P/B OFF. Pneumatic mode for overpressure, electrical mode for engine fire. Pneumatic mode for engine fire, electrical mode for altitude > 15,000 ft. Pneumatic mode for delta pressure, electrical mode for precooler temperature.

The engine air bleed pressure is pneumatically regulated by the __________ when air is supplied by the HP stage, or by the __________ when the air is supplied by the Intermediate Pressure (IP) stage. High Pressure (HP) Valve (VLV), Pressure Regulating Valve (PRV). Bleed Monitoring Computers (BMCs), Wing Anti-Ice (WAI). Pressure Regulating Valve (PRV), High Pressure (HP) Valve (VLV). Wing Anti-Ice (WAI), Bleed Monitoring Computers (BMCs).

When does the HP VLV pneumatically regulate the air supply, and within what pressure range does it operate? (REPETIDA). At low engine speed, 8 to 36 psi. At high engine speed, 44 to 85 psi. At idle, 110 to 240 psi. At high altitude, 15,000 ft to 35,000 ft.

What is the primary function of the IP check valve, and when does it come into play? (REPETIDA). Protects the IP stage from reverse flow when HP VLV is open. Regulates the pressure downstream from the PRV. Monitors engine fire at 450°C. Controls bleed pressure at high altitude.

A ground cart may supply the pneumatic system, and the supply duct is located on the left-hand side of the cross bleed valve. Only the LH bleed system is supplied when the X-BLEED selector is in the ____________ position for ground air supply. OFF. AUTO. OPEN. SHUT.

When the X-BLEED selector is in the SHUT position, the ground air supply will be available to supply the LH and RH systems ____________. simultaneously. independently. alternately. occasionally.

The leak detection system is used to detect leaks in the vicinity of the packs, wings, pylons, and APU hot air ducts. Each wing is monitored by a double loop, and the pylon and APU hot air ducts are monitored by a ____________ loop. dual. redundant. single. triple.

The APU bleed air supplies the pneumatic system through the APU bleed valve if the APU is ____________. operational. running. stopped. in standby mode.
