B. 17,600 feet.
C. 10,000 feet.
 
 
8. From which measurement of the atmosphere can stability be determined?
A. The ambient lapse rate.
B. The dry adiabatic lapse rate.
C. Atmospheric pressure.
 
 
9. What type weather can one expect from moist, unstable air, and very warm surface temperatures?
A. Fog and low stratus clouds.
B. Continuous heavy precipitation.
C. Strong updrafts and cumulonimbus clouds.
 
 
10. A moist, unstable air mass is characterized by
A. cumuliform clouds and showery precipitation.
B. poor visibility and smooth air.
C. stratiform clouds and continuous precipitation.
 
 
11. Which is true regarding a cold front occlusion? The air ahead of the warm front
A. is warmer than the air behind the overtaking cold front.
B. is colder than the air behind the overtaking cold front.
C. has the same temperature as the air behind the overtaking cold front.
12. If a temperature inversion is encountered immediately after takeoff or during an approach to a landing, a potential hazard exists due to
A. strong convective currents.
B. wind shear.
C. strong surface winds.
 
 
13. GIVEN:
Winds at 3,000 feet AGL 30 kts
Surface winds Calm
While approaching for landing under clear skies a few hours after sunrise, one should
A. allow a margin of approach airspeed above normal to avoid stalling.
B. keep the approach airspeed at or slightly below normal to compensate for floating.
C. not alter our approach airspeed, these conditions are nearly ideal.
 
 
14. When flying low over hilly terrain, ridges, or mountain ranges, the greatest potential danger from turbulent air currents will usually be encountered on the
A. leeward side when flying with a tailwind.
B. leeward side when flying into the wind.

B. They form slowly, but move rapidly.
C. They are associated with frontal systems only.
 
 
16. Which is true regarding the use of airborne weather-avoidance radar for the recognition of certain weather conditions?
A. The radarscope provides no assurance of avoiding instrument weather conditions.
B. The avoidance of hail is assured when flying between and just clear of the most intense echoes.
C. The clear area between intense echoes indicates that visual sighting of storms can be maintained when flying between the echoes.
 
 
17. Which feature is associated with the tropopause?
A. Abrupt change in temperature lapse rate.
B. Absolute upper limit of cloud formation.
C. Constant height above the Earth.
