Meteorology 1/2 Flashcards
The supercooled water droplets freeze at ?
-10*c
All supercooled droplets will freeze at
A. -10
B. -25
C. -40
C
What’s the more dangerous type of icing?
The one encountered in dense clouds composed of heavy accumulation of large supercooled drops and freezing rain
How do you call an amount of water intercepted by an aircraft in a given time?
Rate of catch
The rate of catch can varies with 5 things:
Liquid water, size of water droplet, airspeed, type of wing on the aircraft and curvature of the landing edge
The supercooled water droplets can have an effect on which parts of the aircraft?
Wings, control surfaces, propellers, windscreen, canopies and radio antenna
The ice increases lift and decreases drag?
Fault the lift decrease and the drag increase
Name the 4 types of ice
Clear ice, rime ice, mixed ice and frost
Clear ice increases drag at :
A. 300 to 350 percent
B.310 to 350 percent
C. 300 to 400 percent
D. 300 to 500 percent
D
What are the dangers of clear ice
Loss of lift
Increase drag
Increase weight
Vibration caused by the unequal loading on the wings and on the blades of the propellers
Which colors is the rime ice?
Opaque or milky white
The rime ice Is lighter in weight than the clear ice ?
Yes
Which type of ice is white semi-crystalline?
The frost
Is that real is I say the frost increases the aerodynamic?
No the frost alter the aerodynamic
Which temperature is the most dangerous for the carburetor icing ?
-10 to -25 degrees Celsius
