Chapter 15: Icing

Question 1

SCWD Concentration and Size

Answer 1

0 to -20 C = Large SCWD (Clear)
-20 to - 40 C = Small SCWD (Rime)

0 to -10 C = High SCWD Concentration

Question 2

Aircraft Skin Icing (7)

Info, Cloud

Answer 2

Clear Ice: transparent, heavy (Cb, Cu, dense Ns)
Rime Ice: brittle, opaque (Stratiform + Ac)
Hoar Frost: sublimation on contact (humid in cold air)
Glaze Ice: wing coating or horned shape
Mixed Ice: clear + rime (Ns)
Packed Snow: heat on wing melts snow -> compacts

Question 3

Icing Intensity
Affects Intensity (3)

Answer 3

High Velocity: worse (less time to move out of way)
Thin: worse
Orographic: worse

Question 4

Ice Triangle

What is? Produces (2)?

Answer 4

Warm front: warm humid air falls in cold air

produces FZRA, FZDZ

Question 5

Aircraft Systems Icing (3)

Answer 5

Carburator
Turbine intake
Fuel (ice crystals in fuel lines)
