Clear Air Turbulence (CAT)
Usually, high level (or jet stream) turbulence encountered in air where no clouds are present; may occur in non-convective clouds
Low level Turbulence (LLT)
In the 12-5 LLT is defined as turbulence which occurs primarily within the atmospheric boundary layer.
Mountain Wave Turbulence (MWT)
Turbulence produced in conjuction with lee waves
Carburetor Icing
The formation of ice in the throat of a carburetor when moist air draw into the carburetor is cooled to the frost point. Often detrimental to engine operation.
Clear Ice
The formation of a layer of hard, smooth, glossy ice on an aircraft. Clear ice is relatively transparent or translucent; synonymous with glaze. Clear ice is heavy and difficult to remove. Compare with rime icing, runback icing. In 3-6, clear ice is defined as it forms when droplets impacting an airplane freeze slowly, spreading over the aircraft components.
Rime Ice
The formation of a white or milky and opaque granular deposit of ice on an aircraft. most common (colder temperatures)
Supercooled Water Droplets
Liquid cloud or precipitation droplets at subfreezing temperatures.
Steam Fog
In 6-11 Steam fog is defined as when very cold, dry air moves over warm water, air very close to the surface picks up water vapor from the strong evaporation
Slant Range Visibility
This is the oblique distance at which you can see landing aids, such as runway lights and markings.
Turbulence in which an aircraft is tossed violently and is practically impossible to control is called...
Extreme
Maneuvering Speed
An airplane needs to reduce to maneuvering speed when in turbulence.
What speed is used if the turbulence is severe?
Aircraft Maneuvering Speed
Turbulence Intensity
Light, Moderate, Severe, Extreme
What type of icing occurs for temperature below freezing?
Rime Ice
Rime Ice
is easier to remove than clear ice. forms at colder temperatures
Ice that could occur well above freezing is
Vaporization of fuel in carburetor. Evaporation, vaporization, if there is moisture in the air, it will freeze.
Induction icing could occur to an aircraft that
doesn't have a carburetor
Induction icing
close to carburetor has to occur below freezing (air enters the aircraft)
