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

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
When does the ice detector alert the crew?
As long as ice crystals are sensed in the windshield
All answers are incorrect.
As soon and as long as ice accretion is detected
Ice detector is used for visual checking by the crew.
What is the maximum speed at which the wipers can be operated?
168 kts
160 kts
145 kts
120 kts
Choose the best answer regarding the ice and rain memo panel messages.
One of the messages you can find on the Memo panel is for example, an AIRFRAME AMBER steady, when the airframe de-icing system is on.
One of the messages you can find on the Memo panel is for example, an AIRFRAME RED steady, when the airframe de-icing system is on.
One of the messages you can find on the Memo panel is for example, an AIRFRAME CYAN steady, when the airframe de-icing system is on.
One of the messages you can find on the Memo panel is for example, an ANTI ICING AMBER message when the system is working properly.
Where is the ATR 72-600 ice evidence probe located?
On the left wing leading edge
All answers are incorrect.
On the right wing leading edge
On the tail elevator
What is the ice detector PTT pb for?
it is only used when TAT is 7° Celsius during flight with visible moisture.
It is used for testing the ice detector system on ground.
All answers are incorrect.
It is mainly used when Sat is below 5° Celsius on ground.
The Captain's and standby static ports are heated by DC BUS 2, whereas the First Officer's static port heat is powered by DC BUS 1.
DC Bus 1
False
True
DC Bus 2
The MODE SEL AUTO pushbutton is selected to the AUTO position. Which system determines the de-icing cycle?
ADC
AHRS
MFC
MFC and ADC
The engine and airframe anti-ice system requires pneumatic bleed air. Therefore, the bleed air valve must be open in order for the engine and airframe anti-ice system to operate normally.
True
False
Which of the following is false concerning the propeller blade heat?
The heating element on every blade on a propeller are independent from each other.
The inner leading edges of the propellers are electrically anti-iced.
The heat decreases the adhesion strength of the accreted ice, which then causes ice built up on the propellers to shed by centrifugal effect.
Propeller heat is powered by the respective ACW BUS.
While in flight, you encounter icing conditions, and the ICING light illuminates. After a while, the ICING light extinguishes automatically. What does this indicate?
This is normal since you turned on engine and airframe anti-icing on.
Ice is no longer accumulating.
The ice detector system failed.
The airframe is clear of ice.
The amber ICING caption illuminates when the ice detector probe has accumulated ___ of ice.
0.6 millimeters / 0.04 inches
0.8 millimeters / 0.05 inches
0.3 millimeters / 0.01 inches
0.5 millimeters / 0.02 inches

False
True
All flight deck windows are heated to provide anti-icing and defogging.
False
True
