What happens to engine RPM when either engine anti-ice valve is open?
There is a fixed RPM increase.
The N1 limit for that engine is automatically increased.
The N1 limit for that engine is automatically reduced.
There is a fixed RPM increase (3% of nominal N1)
Window heat operation begins:
Automatically after the first engine start.
if the PROBE/WINDOW HEAT push button is selected ON by the crew prior to engine start.
Rain protection is provided by:
Warm bleed air blowing across the windshield.
Rain repellent and Windshield wipers.
Both are correct.
Can the wing anti-ice be tested on the ground?
Yes, with valves only open for 30 seconds.
Yes. Valves stay open till selected off.
No.
Anti-ice and de-icing protection is provided for:
The engine nacelle’s and three outboard wing slats.
The engine nacelle’s, the horizontal stabilizer, and three outboard wing slats.
The engine nacelle’s, the horizontal stabilizer, the vertical stabilizer and three outboard wing slats.
The probe heaters can be activated manually prior to engine start by placing the PROBE/WINDOW HEAT pushbutton.
True
False
What happens to the heat at the drain masts when the aircraft is on the ground?
Nothing.
The heat is reduced to prevent injury to ground personnel.
Some of them are automatically switched off (pitot, AOA).
The RAIN RPLNT (rain repellent) pushbutton is inhibited on the ground when the engines stopped.
True
False
TAT probes are heated on the ground.
True
False
True or False:
True
False
The ON light illuminates on the wing anti-ice P/B:
When the anti-ice valves open
When the P/B is set to ON
When the fault light goes out
When the anti-ice valves open and the fault light goes out.
How is window heating regulated?
Manually by flight crew
Window heat is not regulated!
One Window Heat Computer (WHC) as master, the other as slave
By two independent Window Heat Computers (WHC), one for each side
The Window Heat Computer provides two power levels for the windshield:
High power when above 20,000 ft, low power when below 20,000 ft
High power when OAT < 10 deg.C, low power when OAT > 10 deg.C
High power in flight, low power on the ground
High power in icing conditions (flight only), low power in other conditions.
The engine nacelle is anti-iced by:
Air bleed from the high pressure compressor
Air bleed from low pressure compressor
AC system and air bleed from low pressure compressor
DC system and air bleed from low pressure compressor.
When an engine anti-ice valve is open:
N1 limit is automatically reduced and the idle N1 is automatically increased
N2 of the associated engine is automatically decreased
N2 limit is automatically reduced and N1 limit is automatically increased
There is no change in the N1 and N2 limits.
In the event of a low air pressure:
The engine anti-ice valve opens automatically
There is no effect on the anti-ice valve position
The engine anti-ice valve must be manually closed
The engine anti-ice valve closes automatically
How can you check that engine anti-ice has been selected on?
You can observe the ON light on the associated engine anti-ice P/B and the ENGINE ANTI-ICE message on the ECAM engine page
You can observe the amber warning on the ECAM memo display and the amber anti-ice light on the overhead panel
You can observe the ENGINE ANTI-ICE message on the ECAM STATUS page
You can observe the blue ON light on the associated engine anti-ice P/B and the ENGINE ANTI-ICE memo on the E/WD
The electric windshield wipers are controlled:
Automatically when in heavy rain
By two individual pushbuttons
By one rotary selector for both windshields
By two individual rotary selectors
The wipers can operate at different speeds:

Speed is automatically adjusted depending on rain intensity.
When the wiper is turned off:
The PARK position must be selected to stow the wiper
It continues to run for approximately 6 seconds
