WorksheetsM8.2 Aerofoil Contamination
Total questions: 10
Worksheet time: 10mins
What is the effect of aerofoil contamination on aircraft performance?
Increases lift and reduces drag
Reduces lift and increases drag
Has no effect on performance
Only affects the weight of the aircraft
What does the coefficient of lift assume about the surface?
It is contaminated
It is clean and free from contamination
It is covered in ice
It is wet
Where can ice form on an aircraft when operating at altitude?
On the tail
On the leading edge of the wings
Inside the cabin
On the landing gear
What is the term used for the accumulation of ice layers?
Ice Accretion
Ice Formation
Ice Build-up
Ice Collection
What can happen when an aircraft flies from sub-zero temperatures into warm moist air, such as on descent?
It speeds up
Frost forms
It becomes more fuel-efficient
What can cause frost to form on the wings of an aircraft?
Low speed flight
Cold fuel in the wing tanks
Excessive sunlight
Light winds
Why is rime ice considered brittle?
Due to its crystalline structure
Because it is made of large water droplets
Because it is a heavy coating
Due to its smooth surface
What is a significant effect of accreted ice on an aircraft?
Increases fuel efficiency
Increases the weight of the aircraft
Improves aerodynamic performance
Reduces engine power
What are the dangers associated with clear ice accretion?
Improved lift and stability
Aerodynamic instability and unequal wing loading
Reduced drag and increased speed
Enhanced visibility and control
Which type of ice is considered to be the most dangerous type of icing?
Frost
Clear Ice
Rime ice
