How can the avionics ventilation system be manually overridden?. From the VENTILATION panel. From the CONTROL panel. From the OVERRIDE switch. From the MONITOR panel.

Which component controls and monitors the avionics ventilation system?. Avionics Equipment Ventilation Computer (AEVC). Air Conditioning Pack. Cooling Pack Controller. RAM Air Inlet System.

When does the avionics equipment ventilation system operate?. Continuously with electrical power. Only during flight. Only on the ground. Only when overheat occurs.

How is cabin pressurization controlled automatically?. By Cabin Pressure Controllers (CPCs). By Residual Pressure Control Unit. By Avionics Equipment Ventilation. By RAM Air Inlet System.

What is the function of the Residual Pressure Control Unit (RPCU) when the aircraft is on the ground?. Forces outflow valves to fully open. Controls the cabin temperature. Forces outflow valves to fully close. Monitors the ventilation system.

What prevents excessive positive or negative differential pressure in the aircraft?. Three safety valves at rear pressure bulkhead. 02 Residual Pressure Control Valve. Cabin Pressure Controllers (CPCs). Two safety valves at rear pressure bulkhead.

How should switches be set to the "ON" position to avoid injury?. Using fingers. Using a stick. Using a screwdriver. Using a wrench.

Which areas are connected to the cabin air supply riser ducts for the crew rest compartments?. Areas 1 and 2. Areas 3 and 4. Areas 5 and 6. Areas 7 and 8.

How are the Flow Control Valves (FCVs) operated under normal conditions?. Electrically controlled and pneumatically operated. Manually controlled and pneumatically operated. Automatically controlled. Electrically and hydraulically operated.

What indicates a valve position disagreement on the AIR panel?. FAULT light on the PACK P/BSW. WARNING light on the FCV. ALERT light on the overhead panel switch. CAUTION light on the cabin control panel.

How does the Temperature Control Valve (TCV) modulate the pack discharge temperature?. By adding cold air to the ACM outlet. By adding hot air to the ACM outlet. By adjusting the ram air system. By controlling the pack flow rate.

How is cooling achieved in the event of an Air Cycle Machine (ACM) failure?. By using backup air conditioning packs. By using the heat exchangers and ram air modulation. By using the Flow Control Valves (FCV) and Trim Air System. By using the Crew Rest Compartment ventilation system.

What determines the pack temperature demand calculation?. The lowest temperature demand. The highest temperature demand. The average temperature demand. The median temperature demand.

Which controller manages the air recirculation system?. Pack Controller (PC). Ventilation Controller (VC). Zone Controller (ZC). Temperature Control Valve (TCV).

What happens to the recirculation valves when both packs are off?. They remain open. They close. They partially close. They are manually controlled.

Where is the fan status displayed?. On the ECAM BLEED page. On the ECAM COND page. On the ECAM AIR page. On the ECAM CAB PRESS page.

Where is a fan overheat condition displayed?. On the ECAM COND page. On the ECAM BLEED page. On the OVerHeaT COND FANS RESET P/BSW. On the MAINT panel.

What ensures permanent monitoring of the cooling capacity of the blowing airflow?. Air Data/Inertial Reference Units (ADIRUs). Cooling Effect Detector (CED). Zone Controller (ZC). Temperature Control Valve (TCV).

How are the batteries ventilated?. By an open circuit. By the recirculation fans. By an independent sealed circuit. By the main blowing system.

Where is the emergency ram air inlet flap located on the aircraft?. On the upper fuselage. On the lower left-hand belly fairing of the fuselage. On the lower right-hand belly fairing of the fuselage. Near the landing gear.

What happens to the outflow valves when the emergency ram air inlet flap is closed?. They remain fully open. They remain half open. They close as necessary to maintain cabin pressurization. They open fully.

In what situation does the VC shut down the extraction fan?. During normal flight operations. In case of an emergency configuration. During fan failure. During fan overheat condition.
