1. Describe the stages of a Thunderstorm - ANSWER 1. Cumulus or
Developing stage: Dominated by updrafts
2. Mature Stage: Updrafts and downdrafts
3. Dissipating Stage-Downdraft dominated
2. Describe the Cumulus Stage of a thunderstorm. - ANSWER 1. As water
vapor condenses into liquid, latent heat is released which warms the air at a fast
rate than surrounding air.
2. updrafts hold the water droplets and ice crystals so rain is unable to fall
3. Some updrafts can reach up to 45 MPH
3. Describe the mature Stage of a thunderstorm. - ANSWER 1. The warmer air
continues to rise until it reaches the tropopause where it spreads out horizontally
creating the anvil shape.
2. Water droplets coalesce into larger heavier droplets and freeze to become ice
particles. As they fall the melt to becomes rain.
3. Updrafts can reach 65 MPH or 6000 FPM
4. Down drafts and updrafts occur at this stage
,5. This is the most intense part of the storm (Precip, tb, Thunder and lightning).
4. Describe the dissipating Stage of a thunderstorm. - ANSWER 1.
Predominately downdrafts
2. Microburst
3. downdraft will cut off the inflow of updrafts those dissipating the storm.
5. Is it possible to tell how sever a Thunderstorm is by looking at it? - ANSWER
No, The visible thunderstorm cloud is only a portion of a turbulent system of
updrafts and downdrafts. As such Severe (plane breaking) TB can extend up to 20
NM from a Thunderstorm.
6. How far must you fly from a Thunderstorm? - ANSWER 20 NM
7. How far from a thunderstorm can you expect deadly Microbusts? - ANSWER
10 NM
8. What are some things you should do if you enter a Thunderstorm
inadvertently. - ANSWER 1. prep AC: Tighten Seatbelt and secure lose objects
turn off auto pilot, turn on Pitot heat and carb heat, turn up interior lighting.
2. Don't try to turn around, just fly straight or alter heading to the right a little to
take advantage of cyclonic tail winds.
3. focus on attitude not altitude (let ac Ride the waves).
, 9. Aspects of a Tornado (5 notes) - ANSWER 1. It is rotating funnel shape
cloud linking the ground to a thunderstorm or CB (Sometimes TCU).
2. Mammatus clouds are telltale signs that a funnel cloud is forming.
3. Average forward speed is 30 MPH
4. Wind Speed in a tornado is 40-280 mph.
5. Typically they form after the heavy rain of a TS
10. Airframe icing occurs when - ANSWER Temperature at or below freezing
while flying in visible moisture (Clouds, rain, drizzle) and when super cooled water
strikes airframe.
11. What are three types of icing - ANSWER - Clear
- Rime
- Mixed
12. Describe Clear Icing - ANSWER Occurs in rain and drizzle. The most
dangerous type of icing due to the heavy weight that results. It is found in
Cumulus clouds and is must severe at the top of clouds
13. What affects does icing have on the four forces of flight? - ANSWER 1. Lift
Decreases
2. Thrust Decreases
3. Drag Increases
4. Weight increase
, 14. What is the maximum bank angle which should be used if your Aircraft has
ice? - ANSWER 5 degrees
15. Describe Rime Icing - ANSWER Found at temperatures between -10° and -
20°C
Small water droplets freeze instantaneously, retaining shape
- Air bubbles do not escape, causing opaque (milky white) color and brittleness
- Found in stratiform clouds; stable conditions
16. What are the three factors that have an effect on the rate of ice
accumulation? - ANSWER 1. Airfoil Shape (thinner airfoil collects more ice)
2. airfoil Speed (Higher speed higher catch rate)
3. Droplet size (larger in TCU, CB, ACC)
17. What are the six types of fog - ANSWER UFairs
1. Upslope (Moist air moves up rising Terrain)
2. Frontal (Warmer rain falls into colder area below, typical with Warm fronts or
Trowals)
3. Advection (Common Coastal ares, typical when warm area flows from the sea
to the ground at night )
4. Ice (occurs from exhaust from engines, most be very cold)
5. Radiation (Common on clear nights-Early morning)
6. Steam (occurs over water when dry air cold air mixes with water vapor, eg: Cold
dry air from cleveland flowing into Erie).
