Aircraft Icing

Question 1

They are 3 main types of airframe

Answer 1

Rime ice

Clear ice

Mix ice

Question 2

Ingredients to build up ice on a plane

Answer 2

Temp below 0

visible Moisture

Question 3

Rime ice

Answer 3

This is form by the instantaneous freezing of small supercooled water droplets (skin temp below 0)

Rough milky and opaque looks like the inside of the freezer

Typically layer type clouds like stratus

Question 4

Clear ice

Answer 4

Formed when large supercooled water drops slowly freeze to the aircraft

Smooth and transparent

Most dangerous type of icing

Cumulus

Question 5

Mixed ice

Answer 5

Combination of rim ice and clear ice

Question 6

Ice accumulation factors that have effects on the rate

Answer 6

Airfoil shape

Airfoil speed

Droplet size

Question 7

Airfoil shape characteristics

Answer 7

Thin airfoil tends to to collect ice more than a thick one.

Thin wings collect quicker ice than thick wings

Higher Airspeed result in greater rates of ice accumulation

Question 8

4 icing intensity

Answer 8

Trace
Light
Moderate
Severe
