5-15 min, with downdrafts of up to 6000fpm and headwind losses of 30-90 knots

Question 14

What is Atmospheric stability

Answer 14

The measure of an atmosphere’s ability to resist vertical motion

Question 15

What determines the stability of the air?

Answer 15

Moisture and Temperature

Question 16

What is Stable Air

Answer 16

Cool, dry air, good and generally clear weather. Stratiform clouds and fog, continuous precipitation and smooth air, fair to poor viability.

Question 17

What is Unstable air

Answer 17

Moist and warm, typically forms thunderstorms can can have good visability but rough air

Question 18

Upslope Fog

Answer 18

Requires Wind

Question 19

Steam Fog

Answer 19

Low level turbulence and icing can becom hazardous

Question 20

Precipitation induced Fog

Question 21

Advection Fog

Answer 21

Requires wind, air mass moves inland form the coast in the winter

Question 22

Radiation Fog

Answer 22

Frequency forms when warm moist air exists over low areas on clear and calm nights

Question 23

What is Temperurture inversion and what are its characteristics

Answer 23

When warm air is n top of some cold air. Smooth air and poor visability

Question 24

Warm Front

Answer 24

Rain and low ceilings in from, t-storms less likely

Question 25

Cold Fromt

Answer 25

Cloudy, hail in advance of front, storms along front, clear behind

Question 26

Speed of wind at mountain top level

Answer 26

>25 knots suggests some turbulence

Question 27

When should you be take caution in mountain flying wind

Answer 27

40kt wind

Question 28

Mount flying with stratified clouds

Answer 28

Stable air

Question 29

Moutning flying with lenticular and/or rotor clouds

Answer 29

Suggest mountain wave: expect turnulance many miles to lee of mountains. Relatively smooth flight on the windward side

Question 30

Convective vlouds on mountains

Answer 30

If they are on the windward side it sujests unstable air and turbulence on either side of the mountain

Question 31

What are VFR conditions?

Answer 31

Ceiling>+ 1000ft AGL and/or visibility >=3 miles. Scattered clouds don't mean ceiling

Question 32

What are the conditions necessary for structural icing?

Answer 32

Visible weather(rain, or cloud drops) and temperature of the surface of the object must be 0C or colder

Question 33

What is the first stage of the thunderstorm life cycle?

Answer 33

Updraft varies in strength, extends from near surface to cloud top inadvisable to operate drone( 3-5 mile height)

Question 34

What is the second stage of the Thunderstorm Life Cycle

Answer 34

Precipitations begins to fall from the cloud base and it signals that downdraft had developed and the cell has entered the mature stage(5-10 mile height)

Question 35

What is the third stage of the Thunderstorm life cycle?

Answer 35

Rain has ended, downdrafts abated( 5-7 mile height)

Question 36

High Air Masses

Answer 36

Rotate right, good weather

Question 37

Low air masses

Answer 37

Rotate Left, poor weather

Question 38

What is a frontal passage marked by?

Answer 38

A change in temperature and wind directions
