1. In poorly defined pressure systems layers of jet stream cloudiness are generally:

Answer : Scattered to broken coverage in shallow layers.

Air travels in a "corkscrew" path around the jet stream with upward motion on  the equatorial side. When high level moisture is available cirriform clouds  form on the equatorial side of the Jet Stream in shallow scattered to broken  layers.


3. In what season is clear air turbulence at its worst?
Answer : In the winter.


4. Assuming that the jet stream was positioned to the north of a surface low pressure area, where would clear air turbulence be most likely? 
Answer : North and northeast of the low.



5. You are flying at 40,000 feet, 50 miles east of a mountain range. What statement is true regarding mountain wave CAT: 
Answer : Can still be expected.



6. You are on a flight through forecast turbulence. You can expect to encounter light turbulence approximately:
Answer : 10 - 15% of the time.




9. Dissipation trails (distrails) are:
Answer : Not common.


12. High altitude turbulence associated with a severe thunderstorm is most likely:
Answer : Under the anvil.


MACH Buffet is caused by airflow exceeding the speed of sound.


CRITICAL MACH Number is where Local sonic flow becomes evident.


Q-Corner=Low indicated airspeeds yield high true airspeeds (Mach#) at high angles of attack.


Thinner air t high alt has a significant impact on flt characteristics because Surface control effects, luft, drag, and horsepower are all functions of air density.


Increasing GW or G will increase low-speed buffet and decrease MACH buffet speeds.
