17
Q

List the three stages of A thunderstorm

A

1) Cumulus stage 2) mature stage 3) dissipating stage

18
Q

State the 10 weather hazards a pilot may encounter with a thunderstorm

A

Tornadoes, squall lines, turbulence, icing, hail, low ceiling/visibility, effects on alternators, lightning, wind shear, precipitation

19
Q

What are the causes of a cold front?

A

When cold air replaces warm air and when cold air wedges under warm air pushing it up

20
Q

What are the characteristics of a cold front?

A

Temperature/humidity decreases and pressure decreases with approach and Wind shifts clockwise usually from Southwest to Northwest in the northern hemisphere

21
Q

List the causes of a warm front

A

Advancing mass a relatively warm air is replacing retracting relatively colder air mass

22
Q

List the characteristics of a warm front

A

Wind it ships clockwise from south east to Southwest and precipitation in the form of continuous or intermittent rain or drizzle as much as 300 miles in advance of surface front

23
Q

What are the. Characteristics of a stationary front?

A

Shows little to no apparent movement

24
Q

What are the five types of fog?

A

Radiation, addiction, upslope, steam, frontal

25
Q

What are the conditions favorable for ground fog formation?

A

Clear cool night, light wind (5 kn or less ), small spread between temperature and dewpoint

26
Q

Air traffic controller’s encounter what kind of fog more often than any other variety in the vicinity of the airport?

A

Radiation

27
Q

What is the most dangerous type of fog and why?

A

Advection because it forms rapidly and cover large areas

28
Q

Cold air moving over Warmwater produces what kind of fog?

A

Steam fog

29
Q

What type of ice forms on the fuselage of an aircraft?

A

Structural

30
Q

What is the most serious form of icing?

A

Clear

31
Q

What type of ice has a milky opaque granular deposit with the rough surface?

A

Rime

32
Q

What causes convective turbulence?

A

Uneven heating of earths surface

33
Q

What causes mechanical turbulence

A

Obstructions in the path of the wind

34
Q

What causes wake turbulence

A

Caused by generation of rotary motor off vertices of the wingtips of aircraft

35
Q

What causes windshear

A

Caused by changes in the wind speed and/or direction in short distance

36
Q

What is the function of what is the function of AWOS?

A

Broadcast local minute by minute weather data directly to pilots

37
Q

ASOS was designed to?

A

Designed to support aviation operations and weather forecast activities

38
Q

Terminal aerodrome forecast are issued how often and are valid for how many hours?

A

Issued four times daily and are valid for 24 to 30 hours
