Ice and Rain protection Flashcards
Are the vertical and horizontal stabilizers provided with anti ice protection?
No. Anti ice protection is not required for these surfaces. Tests have proven no significant ice can form there
How many temperature schedules are there for the slats?
- Low for slats retracted, and high for slats extended
Which engine bleed air stage does hot anti ice air come from?
10th stage
Can the APU bleed provide anti ice protection?
No
How are the windshields protected from ice?
They are electrically heated
Which position is the windshield heat switch normally in?
LOW
Are the wings protected from getting too hot, and if so how?
Yes, the anti ice leak controller (AILC) monitors wing temperature, and regulates the anti ice valves to maintain the appropriate temperature
Can one bleed provide air to both wings, and if so how?
Yes, by opening the WING A/I CROSS BLEED selector to the desired side
When is the ice detector test accomplished?
On the 1st flight of the day
What do the PROBES switches do in flight?
Nothing, in flight all probes are fully powered regardless of switch position
When should the WING A/I CROSS BLEED rotary selector be turned?
During a bleed leak condition or an engine failure as directed by the QRH
Which pilots WIPER switch is controlling?
The last one moved
What exceptions are made when type 2 or 4 has been applied to the wings?
Only activate wing anti icing just prior to thrust increase for takeoff
When should the cowl anti ice be turned on in flight?
When in flight icing conditions, or when the ICE message is displayed
When should the wing anti ice be turned on in flight?
When ICE is annunciated by the ice detection system, or while flying in icing conditions with the airspeed of less than 230 KIAS
