ATR 72-600 (Ice and Rain Protection)

Which are the main sources used by the ice and rain protection system?

• Electrical and pneumatic sources

• Pneumatic source, except for boots which use Electrical source

• Just the pneumatic source is used

• Only the Electrical source

What is the meaning of the ENG fault light on the De-ice panel?

• AIRFRAME AIR BLEED pb is selected OFF and air temperature upstream of the de-ice valve exceeds 230° C. Or inflation sequencing of engine boots A or B is not correct.

• All answers are correct.

• Associated distribution valve output has been controlled to close but a downstream pressure is detected.

• Associated distribution valve output has been controlled to open but no downstream pressure is detected.

Where is the ice detector on the ATR 72-600 located?

• On the right wing trailing edge

• On the left wing leading edge

• On the right wing leading edge

• On the left wing trailing edge

Which of the following options represent the correct list of anti-icing advisory system (AAS) components?

• An ice detector, an ice evidence probe, AOA GREEN light on central panel, and ICING AMBER label on FMA

• An ice detector, an ice evidence probe, AOA GREEN light on central panel, ICING AMBER label on FMA, and some labels on memo panel

• Two ice detectors, an ice evidence probe, AOA GREEN light on central panel, ICING AMBER label on FMA, and some labels on memo panel

• Two ice detectors, two ice evidence probes, AOA GREEN light on central panel, ICING AMBER label on FMA, and some labels on memo panel

What happens when you press and hold the ICE DET PTT pb for 3 seconds?

• "Icing" AMBER label On FMA plus "A-ICING DETECT" alert with the associated procedures on EWD plus MC and single chime

• "Icing" AMBER label On FMA plus "A-ICING DETECT" alert without any of the associated procedures on EWD plus MC and single chime

• "Icing" AMBER label On FMA plus "A-ICING DETECT" alert with the associated Procedures on EWD plus MW and continuous repetitive chime

• Nothing happens, because it works (fully) automatically

What is the ATR 72-600 ice detector directly connected to?

• All answers are incorrect.

• Directly connected to the APM

• Directly connected to the MCDU

• Directly connected to the FWS

When can you say icing conditions exist?

• When on ground, you have 5° Celsius or less and when in flight, you have 10° Celsius or less, plus visible moisture

• When on ground, you have 10° Celsius or less and when in flight, you have 5° Celsius or less, plus visible moisture

• When on ground, you have 7° Celsius or less and when in flight, you have 7° Celsius or less, plus visible moisture

• When on ground, you have 5° Celsius or less and when in flight, you have 7° Celsius or less, plus visible moisture.

Where does the bleed air used by the pneumatic system come from?

• Both engines through the left and right de-ice valves

• Engine number one through the right de-ice valve

• Nowhere, the de-icing system does not use bleed air from the engines

• Engine number two through the left de-icing valve

How does the ice detector alert the crew?

• With an MW aural alert

• With a local alert in the overhead panel

• With an MC alert

• With an AMBER ICING message on the FMA

What does the extinguishing of the icing message on the FMA mean?

• It means the end of ice accretion. The aircraft is clear of ice.

• It means that there is a failure. We have to do it manually.

• It means the end of ice accretion. It does not mean that the aircraft is clear of ice.

• It means that the IEP is inoperative
