Types of icing / drag (CheckRide Prep)

Front

Describe Rime ice

Back

-Rough

-Fromed by super cooled water dropelets

Front

Describe clear ice

Back

-Gloosy transparent

-Formed by the relatively slow freezing of super cooled water

-Denser, harder

Front

Mixed ice

Frost

Back

Forms when temperature and dew point are below freezing

-Usually forms in clear, stable air with light winds.

-A heavt coat can cause a 5 to 10 percent increase in stgall speed

Front

Describe Trace icing

Back

Not hazardous unless encountered for an extended period of time

Front

Describe Light Icing

Back

Icing clearly visible, Anti- icing/deicing removes/prevents accumulation

Front

Describe moderate icing

Back

Even short encounters can be hazardous. Anti-icing/deicing equipment must be used. Or diversion

Front

Describe Severe icing

Back

Rate of accumulation is such that deicing/ Anti-icing equipment fails to reduce the hazard.

-Diversion is mandatory

Front

What is Bernoulls Principle

Back

-Basic principle that allows for the creation of lift

-As air passing above the wing accelerates, it creates an area of low pressure above the wing. This pressure differential pushes the wing upward

Front

What is Parasite Drag

Back

Drag produced by the motion of an object through a fluid

-Things on the aircraft that do not produce lift

-like the fuselage/ landing gear

Front

What is Induced drag

Back

drag that arises from the development of lift
