Chapter 15: Icing Flashcards
1
Q
SCWD Concentration and Size
A
0 to -20 C = Large SCWD (Clear)
-20 to - 40 C = Small SCWD (Rime)
0 to -10 C = High SCWD Concentration
2
Q
Aircraft Skin Icing (7)
Info, Cloud
A
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

Q
Icing Intensity Affects Intensity (3)
A
High Velocity: worse (less time to move out of way)
Thin: worse
Orographic: worse
4

What is? Produces (2)?
A
Warm front: warm humid air falls in cold air
produces FZRA, FZDZ
