Weather Review Quiz

1. Question

What is the ultimate cause of weather?

Unequal heating of the earth's surface
Wind
Geography and proximity to the ocean
Ocean currents

2. Question

In simple terms, atmospheric pressure is…

The weight of air pushing down on earth
Average windspeed over an area
A combination of updrafts and downdrafts in an area

3. Question

Pressure Altitude is…

The height above or below standard pressure
The spot in the atmosphere where air pressure is 29.92'' Hg
The pressure at a given altitude
Field elevation

4. Question

Density Altitude is…

Pressure altitude corrected for non-standard temperature
Always the same for a given true altitude
Standard pressure corrected for different temperatures
Lower as temperature increases

5. Question

The spread between temperature and dewpoint is significant because…

A close spread is conducive to forming clouds or fog
High turbulence is found where the spread is low
Temperature and dewpoint spread is a major factor in atmospheric stability
Thunderstorms immediately form where temperature and dewpoint are close

6. Question

Cirrus clouds are comprised of…

Ice crystals
Super-cooled large droplets
Smog particles

7. Question

What temperature range indicates a cold air mass?

No specific temperature. The naming refers to the relative temperature of that air mass to the air around it.
In the mid-latitudes, below 0°C
In the northern latitudes below -20°C
Always at or below 0° C

8. Question

Generally speaking, when a warm air mass meets a cold air mass, what happens?

The warm air mass is pushed upwards and moves over the cold air mass
The cold air mass is pushed upwards and moves over the warm air mass
The air masses mix perfectly, creating one large luke-warm air mass
The air masses, afraid of conflict, will turn around and head in the opposite direction

9. Question

What is a front?

A line where two air masses meet
Any place a storm begins to form
Any line where wind speeds are greater than 30kt

10. Question

Which front tends to generate the most violent weather, including squalls?

Cold front
Warm front
Stationary front
Occluded front

11. Question

Which fronts are capable of creating bad weather that prevents safe VFR operations? Select all that apply.

Cold front
Warm front
Stationary front
Occluded front

12. Question

What is a primary way to determine atmospheric instability?

High temperature lapse rate
High temperature/dewpoint spread
Low temperature lapse rate
Precipitation

13. Question

What are the three stages of thunderstorm development? (Select all three)

Cumulus
Mature
Dissipating
Shear stage

14. Question

What are hazards associated with flying in thunderstorms? (select all that apply)

Hail damage to aircraft
Severe icing
Severe turbulence
IFR conditions

15. Question

Microbursts are usually associated with

Thunderstorms
High winds across mountains
Windshear in the jet stream
Stationary fronts

16. Question

What factors make ice a significant hazard, especially to small aircraft? (Select all that apply)

Increased weight
Decreased engine performance due to propeller and intake icing
Decreased lift
Reduced visibility from windshield ice

17. Question

What consideration should a pilot make when landing with ice?

Land without flaps
Approach slower than normal
Approach at least 30kt above normal approach speed
Keep the autopilot on as long as possible

Private Pilot Helicopter
