Engine Anti-ice Valves will open.

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

Correct! Wrong!

The ice detection system has _____.

One ice detector that measures ice accretion.

Two ice detectors that measure ice accretion.

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

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 ANTI ICE ENG p/b FAULT light comes ON:

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

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

Only when the Wing Anti-ice Valve fails.

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.

True.

False.

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.

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 and probe heating.

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

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

Correct! Wrong!

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.

False.

True.

Correct! Wrong!

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

On high heat only.

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

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

Correct! Wrong!

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

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

All slats remain heated.

Slats are not heated.

Correct! Wrong!

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

The engines and wings anti-ice must be selected.

The engines and wings anti-ice are automatically selected.

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

Correct! Wrong!

When SEVERE ICE DETECTED is displayed:

The engines anti-ice is automatically selected.

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

The engines and wings anti-ice are automatically selected.

Correct! Wrong!

Which of the following statements is true ?

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

On ground, TAT probes are not heated.

On ground, Static ports are heated.

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!

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.

3 minutes.

1 minute.

Correct! Wrong!

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

True.

False.

Correct! Wrong!

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

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

Outboard slats and the horizontal stabilizer.

Outboard slats.

All slats.

Correct! Wrong!

The Captain and First Officer windshields each has a _____

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

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

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

Correct! Wrong!

If Window Heat Computer 1 (WHC 1) fails: All window heat is lost on left side and it may be recovered.

The left side window heat is lost.

WHC 2 takes over and all windows remain heated.

WHC 2 takes over and Left side-windows remain partially heated.

Correct! Wrong!

The wing anti-ice valves automatically close if _____

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

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

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

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.

The Probe and Window Heat System is controlled by:

2 WHC and 1 p/b.

2 WHC and 2 p/b.

1 WHC and 1 p/b.

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.

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

Remain in the current position.

Close automatically.

Open automatically.

Correct! Wrong!

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

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

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

Fully automatic.

Correct! Wrong!

The WIPER selector has two speeds: slow or fast.

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

It can be selected only below 230 Kt.

It may be used at any time.

Correct! Wrong!
