"What are the main sources of high-pressure (HP) air supply for the pneumatic system on the Airbus A320 family? ". Engines, APU, and external ground source. Engines, APU, and external ground.

What is the function of the High Pressure Bleed Valve (HPV)?. To supply air from the HP stage when engines are at low power. To supply air from the HP stage when engines are at low.

During ground operations, the left pneumatic system is supplied by an external HP ground unit. The right system also needs bleed air. What action should maintenance personnel take?. Open the crossbleed valve to allow supply from the left system. Open the crossbleed valve to allow supply from the left.

Which of the following components are responsible for bleed air temperature regulation?. FAV and precooler. FAV and lover.

During troubleshooting, the ECAM displays a class 2 maintenance message “AIR BLEED” related to high precooler outlet temperature (240°C). Which component(s) should be suspected according to the ma... Thermostat (CTL THERMST), FAV, or sense line. Thermostat ( THERMST), FAV, or sense line.

Which component operates the X-BLEED valve in automatic mode?. The primary DC motor under BMC control. The secondary DC motor under ECB control. The PRV through pneumatic actuation.

During troubleshooting, BMC 1 fails. What is the consequence for leak detection and ECAM warnings?. ECAM warnings (overpressure, overtemperature, wing leak) are still available, but ENG BLEED LEAK and APU BLEED LEAK warnings are lost. ECAM warnings (overpressure, overtemperature, wing leak) are still available, but ENG BLEED LEAK and APU BLEED LEAK warnings.

CFM LEAP 1A- During a pneumatic system test, the HPV solenoid is de-energized. What is the expected position of the HPV?. It moves to the fully closed position. It moves to the fully closed.

CFM LEAP 1A - During engine start, the OPV fails in the closed position. What maintenance action is available to allow the start?. Use the manual override and lock the valve in the open position. Use the manual override and lock the valve in the open.

What does the dual Bleed Temperature Sensor (BTS) provide to the BMCs?. Actual EBAS temperature downstream of the precooler. Actual EBAS temperature downstream.

What is the main function of the Pack Flow Control Valve (FCV) in the Airbus A320 family?. To adjust the flow rate through the pack and act as the pack shut-off valve. To regulate hot air temperature before entering the pack.

During a cabin temperature imbalance report, the forward cabin is too cold while the cockpit and aft cabin are normal. Which component is most likely at fault?. The related Trim Air Valve for the forward cabin. The Trim Air Pressure Regulating Valve for the forward cabin.

During maintenance, both automatic pressurization systems (CPC) fail. Which component allows manual control of the outflow valve?. The third motor installed for manual operation. The Residual Pressure Control Unit (RPCU).

What is the purpose of the avionics ventilation system on the Airbus A320 family?. To provide cooling air to avionics equipment, flight deck instruments, and circuit breaker panels. To regulate pressurization of the avionics bay.

How many skin valve configurations are available in the avionics ventilation system?. Three: open circuit, closed circuit, and intermediate circuiten la cabina. Fort: open circuit, closed circuit, and intermediate circuiten la cabina.

During ground operations with low outside air temperature, which configuration is expected for the avionics ventilation system?. Closed circuit with both valves closed. Intermediate circuit with inlet closed and outlet partially open.

Which system controls the operation of the isolation valves and the extract fan in the cargo ventilation system?. Cargo Ventilation Controller (VC). Air Conditioning System Controller (ACSC).

What is the function of the water extractor in the pack system?. To remove water particles from the air entering the turbine. To remove water particles from the air leaving the turbine.

During an engine start sequence with the crossbleed valve open, what is the expected position of the pack Flow Control Valve (FCV)?. Closed automatically, then reopens 30 seconds after the end of the start sequence. Closed automatically, then reopens 40 seconds after the end of the start sequence.

Which of the following is NOT a function of the Flow Control Valve (FCV) within the Flow Control Unit (FCU)?. Catalytic removal of ozone from the bleed air. Catalytic removal of ozone.
