ANSWER-Wind Shear
Lightning - CORRECT ANSWER-
Tornado - CORRECT ANSWER-
Microbursts - CORRECT ANSWER-
the dissipating stage of a thunderstorm - CORRECT ANSWER-Mostly
downdrafts, maybe light rain
,wind shear - CORRECT ANSWER-A drastic change in wind velocity and/or
direction in a vertical or horizontal plane.
What is Virga? - CORRECT ANSWER-Rain that evaporates before hitting the
ground causing strong downdrafts.
Describe a microburst - CORRECT ANSWER-Very strong winds, generally
lasts about 5 minutes, can be up to 1 mile wide, very localized column of
sinking air causing intense downdrafts. Look for an upside down
mushroom cloud.
What are the 3 different types of Icing? - CORRECT ANSWER-1 Clear
2 Mix - CORRECT ANSWER-
3 Rime - CORRECT ANSWER-
Describe Clear Icing, when does it happen and why is it a problem? -
CORRECT ANSWER-Happens at 0 to -10 Degrees Celsius.
Forms slowly across entire airfoil, creates lots of weight (so you have to pull
more power) Ice sheds off rotor and hits tail rotor. - CORRECT ANSWER-
Describe Rime Icing, when does it happen and what do you do? - CORRECT
ANSWER--15 to -20 Degrees Celsius.
,Forms fast, traps 02 in the ice causing opaque color. - CORRECT ANSWER-
Forms on leading edge disrupting airflow. Depart or land. - CORRECT
ANSWER-
Describe mix Icing, when does it happen? - CORRECT ANSWER-Mix
between Clear and Rime.
-10 to -15 Degrees celsius - CORRECT ANSWER-

5 Type: UA (Upper Air) or UUA (Urgent upper air) - CORRECT ANSWER-
6 Weather - CORRECT ANSWER-
, Contact Flight Watch 122.0 - CORRECT ANSWER-
What does an Area Forecast include? - CORRECT ANSWER-1 Synopsis
(Good for 18 hours. Contains big picture, pressure systems.
2 Forecast (Good for 12 hours. Contains weather, clouds, rain, wind) -
CORRECT ANSWER-
3 Outlook (Good for 6 hours. VFR, IFR, MFR) - CORRECT ANSWER-
*All come out every 8 hours.* - CORRECT ANSWER-
negative temperatures - CORRECT ANSWER-On the Winds/Temps aloft
what do you assume above 24,000FT?
In Winds/Temps aloft, what do you do if the heading is impossible? -
CORRECT ANSWER-Subtract 50 and add a zero for heading. For example,
75-50=25 add the zero, get 250)
