A330 ATA 30 - ICE & RAIN PROTECTION

What is the primary purpose of the Ice and Rain Protection System?. To prevent ice formation on the fuselage. To ensure safe operation in icing conditions. To maintain cabin temperature. To improve aerodynamic efficiency.

Which systems provide failure data to the Centralized Maintenance Computer (CMC)?. Wing ice protection and engine air intake ice protection. Wing ice protection and probe ice protection. Wing ice protection and windshield anti-icing. Wing ice protection and potable and waste water ice protection.

How is the wing ice protection system heated?. Electrical heating elements. Bleed air from the pneumatic system. Hot air from the engines. Electrical and hot air combined.

How many Wing Anti Ice (WAI) valves are used for each wing?. One for each slat. One for the entire wing. Two, one for slat four and one for slats five to seven. Two, one for slats one to three and one for slats four to seven.

What is the role of the engine air intake anti-ice valve?. To regulate the flow of fuel to the engine. To control the amount of hot air bled from the HP compressor for ice protection. To monitor engine temperature. To provide feedback to the FADEC.

How is the engine air intake ice protection system status displayed?. On the pilot's primary flight display. On the engine control panel. Through the SDAC and displayed on the ECAM. Via a dedicated ice protection panel.

What is the function of the Probe Heat Computer (PHC)?. Controls heating for static probes, AOA, pitot, and TAT sensors. Monitors the engine performance in cold conditions. Controls the windshield heating system. Controls the heating of fuel lines.

What is the primary function of windshield heating?. To de-ice the windshield. To defog the windshield. To maintain clear visibility in icing or misting conditions. To heat the cockpit.

How does the windshield heating system operate on the ground and in flight?. It operates at full power on the ground and low power in flight. It operates at low power on the ground and full power in flight. It operates at full power at all times. It operates only in icing conditions.

How is rain removed from the windshield in heavy rain conditions?. By a high-speed fan. By heated glass. By a rain repellent system and windshield wipers. By a water-repellent coating on the windshield.

What is the function of the rain repellent fluid FORALKYL 2211?. To lubricate the windshield wipers. To dissolve ice on the windshield. To remove rain from the windshield. To clean the cockpit windows.

When is the rain repellent system inhibited?. When the engines are running. When the engines are not running on the ground. When the aircraft is in flight. When the windshield wipers are in use.

How is the wing ice protection system divided for each wing?. Into three subsystems. Into four subsystems. Into two subsystems. Into a single subsystem.

Where is the wing anti-ice valve installed?. In the cockpit. In the landing gear bay. In the fixed leading edge of the wing. In the engine nacelle.

Where is the bleed air for engine air intake ice protection sourced from?. The first stage of the engine compressor. The second stage of the engine compressor. The third stage of the engine compressor. The fourth stage of the engine compressor.

How is the engine air intake ice protection system controlled and monitored?. By the Flight Management System (FMS). By the Full Authority Digital Engine Control (FADEC). By the aircraft's pneumatic system. By the Central Maintenance Computer (CMC).

Where is the engine anti-ice valve located?. On the upper right side of the engine. On the lower left hand side of the engine. Inside the cockpit. In the landing gear bay.

What forces contribute to the piston moving to the open position when the solenoid is de-energized?. Only the actuator spring force. The actuator spring force and clock spring forces. Only the air pressure on the retract side. The air pressure on the extend side and mechanical linkage.

How does the Probe Heat Computer (PHC) contribute to probe efficiency?. It cools the probes. It provides backup power. It ensures permanent monitoring of probes. It reduces electrical consumption.

Which probes are heated by the standby system?. All probes including TAT. Only static ports and AOA. Only pitot and static ports. All probes except TAT.

When are the TAT probes heated?. Only on the ground. Only in flight. Both on the ground and in flight. When manually activated.

How is the automatic operation of the probe heating system overridden?. By turning off the engines. By using the Probe & Windows Heat P/BSW. By engaging the landing gear. By increasing the aircraft's speed.

What system generates an ECAM and an aural warning in case of a probe heating fault?. The Central Maintenance Computer (CMC). The Flight Warning Computer (FWC). The Air Data/Inertial Reference Unit (ADIRU). The Engine Control Unit (ECU).

What role does the Central Maintenance Computer (CMC) play in the probe heating system?. It provides power to the probes. It transmits fault messages. It controls the heating levels. It overrides the Probe Heat Computer (PHC).

What ensures rain removal from the windshield in heavy rain conditions?. Increased airflow over the windshield. Manual cleaning by the crew. Two independent wipers and a rain repellent liquid. Automatic windshield heaters.
