|
What sources are used for anit-icing and de-icing?
|
Bleed air
Electric |
|
|
What uses bleed air for ice protection?
|
Engine heat
3 outboard slats |
|
|
What uses electric heat for ice protection?
|
Pitot static system
Windshields Water lines Pressurization static port |
|
|
If an engine fails, does that side receive ice protection?
|
Yes, the crossbleed valve opens to provide symmetrical ice protection for both wings
The failed engine will not receive heat |
|
|
How many ice detectors must be working to have ice detection?
|
One
|
|
|
How long will the anti-icing system remain on after icing is no linger detected?
|
5 minutes
|
|
|
If ICING on the MCDU is set to OFF and on takeoff roll icing conditions are encountered, will the anti-icing system turn on?
|
Not until 1700 ft or 2 minutes after takeoff
|
|
|
Can the APU be used to provide bleed air for anti-icing?
|
No
|
|
|
How is ice detected in flight?
|
2 ice detectors
Vibrating sensor element that changes frequency when ice builds up around it Once ice is detected, the sensor is heated to see if icing conditions continue |
|
|
What happens if there is a single bleed source failure?
|
The crossbleed automatically opens
|
|
|
How should the MCDU be set if there are icing conditions present on the ground?
|
ALL
|
|
|
What does selecting ALL on the MCDU provide?
|
Engine: ON when running
Wing: ON at 40 knots |
|
|
If ALL is selected, at what point does the anti-icing system become automatic?
|
1700 AGL or 5 minutes after takeoff
|
|
|
If OFF is selected, at what point does the anti-icing system become automatic?
|
1700 AGL or 2 minutes after takeoff
|
|
|
How does the failure of one power source affect the windshield heating system?
|
Ground: inhibited
Flight: Left side heated |
|
|
When do the smart probes heat?
|
Engines running
|
|
|
Is there a test for the anti-icing system?
|
Yes, but only performed by mx
|
|
|
How should the aircraft be configured for deicing?
|
Bleeds OFF
Stab trim: full nose down Flaps UP Engines and APU ON of OFF |
