Q

How does the probe heat heating work?

A

Electrical heating protects pitot heads static ports Angle-Of-Attack probes (AOAs) and Total AIr Temperature (TAT) probes. Three independent Probe Heat Computers (PHCs) automatically control and monitor Captains probes F/O probes and STYBY probes.

Q

Are the TAT probes heated on the ground?

A

On the ground the TAT probes are not heated and pitot heating operates at a low level (the changeover to normal power in flight is automatic).

Q

What does a “FAULT” light in the ENG ANTI ICE pushbutton indicate?

A

Switch/anti-ice valve disagreement

18
Q

With ENG ANTI ICE ON what indications will you see?

A
  • Blue ENG ANTI ICE light ON
  • ECAM: ENG ANTI ICE
  • ECAM: IGNITION
  • N1 limit is reduced (amber tick on N1 indicator)
  • N1 idle is increased
19
Q

What should you do if there is significant engine vibration due to ice?

A

Increase N1 to 70% for a minimum of 15 seconds prior to selecting a higher thrust

20
Q

With engine anti-ice ON, is your descent affected?

A

Yes, because idle thrust is increased

21
Q

Should you use wing anti-ice on the ground?

A

No

22
Q

Can you use the APU bleed for wing anti-ice?

A

No

23
Q

What does the amber “FAULT” light in the WING ANTI ICE pushbutton indicate?

A
  • Switch/anti-ice valve disagreement

- Low pressure is detected

24
Q

What is the maximum windshield wiper operation speed?

A

230 Knots

25
Q

What happens when the RAIN RPLNT pushbutton is pressed?

A

Timer applies a measured quantity of rain repellent to the windshield

26
Q

What part of the wing is heated?

A

Outboard 3 slats

27
Q

What happens if you turn the anti-ice switch on, on the ground?

A

The wing anti-icing valves will open for a 30 second test

28
Q

With the PROBE/WINDOW HEAT pushbutton ON will the heaters automatically switch to AUTO?

A

No

29
Q

On the ground, with the PROBE/WINDOW HEAT pushbutton in AUTO, when are the probe and mast heaters activated?

A
  • LOW with at least one engine running (except the TAT probe - not heated on ground)
  • NORMAL is automatically selected after T/O
30
Q

When will the RAIN RPLNT pushbutton not work?
