1
FAA 9-1 BL When will clouds, fog, or dew will always form?

water vapor condenses
2
growth process that allows cloud droplets to grow large and heavy enough to fall as precipitation are normally result from?

Sufficient lift

3
When do Ice pellet (sleet) occur?

when there is a shallow layer aloft with above freezing temperatures and with a deep layer of below freezing air based at the surface.

4
When does freezing rain occur?

when there is a deep layer aloft with above freezing temperatures and with a shallow layer of below freezing air at the surface.

5
BL 9-5 ice pellets in the lower altitude means?

freezing rain presents at a higher altitude.

6
BL 9-6 What is an indication of rain which freezes on impact?

Temperatures are above freezing at higher altitudes.
7
BL 9-7 Which precipitation normally means that there are freezing rain at higher altitudes?

Ice pellets.

8
BL. 9-8 Freezing rain occurs when there is a deep layer aloft with ______ freezing temperatures and with a shallow layer of ____freezing air at the surface.

Above, below
9
Why do you have to avoid tailwind on take off?

to avoid longer take off distance

10
9-10 What is an important characteristic of wind shear?

it can be present at any level and can exist in both a horizontal and vertical direction

11
FA. A strong wind shear can be expected

On the low-pressure side of a Jetstream core where the speed at the core is stronger than 110 knots

12
BL 12 Squalls means?

a sudden onset in which the wind speed increases at least 16 knots and is sustained at 22 knots or more for at least one minute.

13
BL 13 Where is hazardous wind shear is common?

temperature inversion and near thunderstorms.
