Correct! Wrong!

The MFPs, the static probes, and the fourth AOA probe are automatically heated to prevent ice formation.

False.

True.

Correct! Wrong!

The pitot probe and the static probes of the ISIS are also automatically heated.

On ground and at ramp, windshields, windows and probes are heated:

Automatically when engine 2 or 3 is running or if PROBE/WINDOW HEAT p/b is ON .

On high heat only.

On low heat when engine 2 or 3 is running and high heat if PROBE/WINDOW HEAT p/b is ON.

Correct! Wrong!

The aircraft on ground and ANTI ICE WING p/b is set to ON:

Wing Anti-ice Valves will open for 30 seconds and then close as a ground check is initiated.

Wing Anti-ice Valves will remain opened until the ANTI ICE WING p/b is selected OFF.

Engine Anti-ice Valves will open.

Correct! Wrong!

In case of electrical power supply failure, the Wing Anti-ice Valves:

Remain in the current position.

Close automatically.

Open automatically.

Correct! Wrong!

Hot air from the pneumatic system can be used to prevent ice accretion on slats 1, 2 and 3.

True.

False.

Correct! Wrong!

Hot air from the pneumatic system can be used to prevent ice accretion on slats 3, 4 and 5.

If a wiper is blocked when commanded on, the wiper actuator command is stopped, in order to preserve the wiper motor. The normal use of the wiper is recovered by switching the WIPER selector off then on again when the wiper is unblocked.

True.

False.

Correct! Wrong!

The WIPER selector has two speeds: slow or fast.

It can be selected only below 230 Kt.

It may be used at any time.

There is a speed limitation only for the high speed position.

Correct! Wrong!

When the ice detection system send the message SEVERE ICE DETECTED:

All anti-ice system must be selected until message ICE NOT DETECTED is displayed.

The engines and wings anti-ice must be selected.

The engines and wings anti-ice are automatically selected.

Correct! Wrong!

When SEVERE ICE DETECTED is displayed:

The engines and wings anti-ice must be selected without delay.

The engines and wings anti-ice are automatically selected.

The engines anti-ice is automatically selected.

Correct! Wrong!

The Captain and First Officer windshields each has a _____

Four-speed electric wiper, including two intermittent speed settings.

Five-speed electric wiper, including three intermittent speed settings.

Six-speed electric wiper, including three intermittent speed settings.

Correct! Wrong!

When ANTI ICE ENG p/b are set to " On ", each engine nacelle is anti-iced by:

Pneumatic system.

Electric heat elements.

Independant bleed air source from the HP compressor.

Correct! Wrong!

The ice protection system protects the critical areas of the aircraft against ice in order to enable unrestricted operation of the aircraft in icing conditions. The ice protection system uses electrical power for:

Window heating, water/waste drain masts heating, outflow valve heating and probe heating.

Window heating and probe heating.

Window heating, water/waste drain masts heating and probe heating.

Correct! Wrong!

Hot air from the pneumatic system provides wing anti-ice to:

All slats.

Outboard slats and the horizontal stabilizer.

Outboard slats.

Correct! Wrong!

The ANTI ICE ENG p/b FAULT light comes ON:

When an Engine Anti-ice Valve is faulty or the valve is in transit when p/b is pushed.

Only when more than one Engine Anti-ice Valve has failed on each side.

Only when the Wing Anti-ice Valve fails.

Correct! Wrong!

The ice detection system has _____.

Three ice detectors that measure ice accretion (two main detectors and one standby detector).

One ice detector that measures ice accretion.

Two ice detectors that measure ice accretion.

Correct! Wrong!

There is one ice detector on each side of the fuselage, on the lower part of the nose fuselage. Each ice detector has a probe that measures icing.

The Probe and Window Heat System is controlled by:

2 WHC and 2 p/b.

2 WHC and 1 p/b.

1 WHC and 1 p/b.

Correct! Wrong!

The wing anti-ice valves automatically close if _____

The OAT is above 30 deg.C (86 deg.F).

The SAT is above 30 deg.C (86 deg.F).

The OAT or SAT is above 30 deg.C (86 deg.F).

Correct! Wrong!

If icing is not detected for approximately _____, and if wing anti-ice and/or engine anti-ice are on, the ECAM displays the green ICE NOT DETECTED memo.

2 minutes.

1 minute.

3 minutes.

Correct! Wrong!

There is an inner and outer wing anti-ice valve on each wing. If the left inner valve fails to open:

Slats are not heated.

All slats remain heated.

One slat is not heated and the flight crew must avoid icing conditions.

Correct! Wrong!

The rain repellent system is operative, when at least one engine is running.

False.

True.

Correct! Wrong!

The rain repellent system is operative, when the engines are running. When sprayed on the windshield, rain repellent fluid increases the surface tension of the water.

Which of the following statements is true ?

On ground, Static ports are heated.

On ground, TAT probes are not heated.

On ground, Static ports and TAT probes are not heated.

Correct! Wrong!

Pitot heating - The change over from low level to high level:

Fully automatic.

Automatic when TAT is at or below -5 deg.C

Automatic when OAT is at or below -5 deg.C

Correct! Wrong!

If at least one ice detector detects icing conditions, and if engine anti-ice is off, the ECAM triggers the amber A-ICE ICE DETECTED alert.

False.

True.

Correct! Wrong!

If 0.5 mm of ice builds up on any probe, the ice detection system informs the anti-ice control system of icing conditions.
