Hint	Answer	% Correct
Plane axis that is perpendicular to the centerline	Pitch	100%
Plane axis that is concerned with centerline, impacts front-back movement	Roll	100%
Plane axis that is perpendicular to the wings and impacts tail-nose movement	Yaw	100%
The principle where, if a fluid is compressed into a narrow space, it will speed up as it races to get out of the narrow compression	Bernoulli's Pinrciple	0%
A cloud that forms when air travels windward and descends rapidly due to a stable layer at the top of a mountain	Cap cloud	0%
Turbulence where this is no change in altitude/attitude of aircraft	CHOP	0%
Some patterns that indicate enhanced turbulence threats are:	Cutoff lows/sharp ridges/sharp troughs/negative tilt troughs/confluent and diffluent jet area/deformation zone	0%
Temperature gradients will cause these types of circulations	Direct thermal circulation	0%
Aircraft violently tossed around and impossible to control	Extreme turbulence	0%
T or F: Clear Air Turbulence is a lower-level turbulence that is completely clear	F	0%
A strong area of subsidence on the leeward side of a mountain	Foehn Gap	0%
Name cloud formations that indicate the presence of clear air turbulence	Gravity waves/Kelvin-Helmholtz waves	0%
Something that impacts turbulence	Increased airspeed/non-level flight/ascending patterns/descending patterns/decreased aircraft weight/decreased wing surface area/increased altitude/decreased density	0%
Dynamics will cause these types of circulations, but different temperature air masses will be involved	Indirect thermal circulation	0%
Slight, erratic changes with no change in altitude/attitude	Light CHOP	0%
Slight, erratic changes in altitude/attitude	Light turbulence	0%
Surface heating will relate to this	Low-level thermal turbulence	0%
Occurs within < 15,000 ft of the atmosphere, in the planetary voundary layer	Low-level turbulence	0%
Surface level winds and friction will impact this	Mechanical low-level turbulence	0%
Rapid bumps or jolts with no change in altitude/attitude	Moderate CHOP	0%
Changes to altitude and attitude of the aircraft where the pilot is still in control	Moderate turbulence	0%
Severe upper-level turbulence associated with "mountain lee waves"	Mountain Waves	0%
The most important feature for identifying where areas of clear air turbulence will be	Polar front jet	0%
Form from eddies off of mountain waves. Stationary/slow in nature	Rotor clouds	0%
Classifications that CHOP does not exist for	Severe/Extreme	0%
Large, abrupt changes in altitude/attitude, large variations in indicated airspeed	Severe turbulence	0%
Pancake-like clouds that will indicate strong wind shear at the top of mountains	Standing lenticular clouds	0%
This is turbulence that is more influenced by irregular air movements	Upper-level turbulence	0%
Low-level turbulence generated by aircraft that occurs < 15,000 ft AGL. Frictional forces in the PBL influence it	Wake	0%
Areas of strongest Clear Air Turbulence will be in areas of strong ____ _____ and _____ _______	wind shear/stable layers	0%
