Ice&rain Flashcards
What temp is clear ice produced
0 - minus 10
What temp is rime ice produced
-10 and below
Problems with ice
Decreases lift
Increases weight
Increases drag
What is thermal wing anti-icing
Warm air from engines used to anti ice
If ice gets into the engine what happens
Disturbs air flow
What are the two types of ice detection
Optical and rotary
How is optical ice detection operated
Performed manually and used before ice builds up
How may detectors does rotary type have
2
Where is rotary type detectors mounted
Forward fuselage
What does hydrophobic coating do
Increase angle to 100 degrees
When is high contact used
More then 80 degrees , rain repellent fluid
How is ice detected by electronic ice detectors
Decreases frequency of vibrating probe tip
Method used to remove snow and ice
De icing followed by procedures
How are the engine and wing thermal anti ice systems operated
Each engine has its own switch
Left and right wings controlled by same switch
What are the restrictions for windscreen wipers
On only when aircraft is wet
Speed has to be less then 250 knots
