Question 1

What is a gust front?

Accepted Answer

The leading edge of cool, gusty surface winds originating from a thunderstorm downdraft, often felt before the rain arrives

Answer

The exact centre of a high-pressure system

Answer

The leading edge of a warm front moving over the ocean

Answer

A clear, calm area immediately preceding a fog bank

Question 2

What is the 'Urban Heat Island' effect?

Accepted Answer

The phenomenon where urban areas are significantly warmer than surrounding rural areas due to human activities, concrete/asphalt absorbing heat, and lack of vegetation, creating localized thermals and altered wind patterns

Answer

Cities generating their own magnetic fields

Answer

A tropical island located in the middle of a large city

Answer

The fog that forms exclusively over skyscrapers

Question 3

In an aviation weather forecast (TAF), what does the abbreviation 'TEMPO' indicate?

Accepted Answer

Temporary fluctuations in the forecasted weather, lasting for less than one hour at a time

Answer

A permanent and complete change in the weather conditions

Answer

A gradual change occurring over several hours

Answer

The exact temperature at the airport

Question 4

In a METAR report, what does the weather abbreviation 'BR' stand for?

Accepted Answer

Mist (from the French 'Brumes')

Answer

Broken clouds

Answer

Heavy Rain

Answer

Blowing Sand

Question 5

On a sunny afternoon, a pilot flying a drone from a dark asphalt parking lot over a cool lake should anticipate:

Accepted Answer

A strong thermal updraft over the asphalt, followed by sinking air (subsidence) over the cooler water, requiring throttle adjustments to maintain altitude

Answer

Perfectly smooth, uninterrupted flight at all times

Answer

A sudden loss of GPS signal over the water

Answer

The drone's compass reversing its polarity

Question 6

An 'Absolutely Stable' atmosphere is characterized by:

Accepted Answer

A temperature lapse rate that is less than the moist adiabatic lapse rate, meaning any displaced air parcel will tend to return to its original position (resists upward motion)

Answer

Continuous, severe thunderstorms

Answer

Winds exceeding 50 knots

Answer

A complete absence of clouds forever

Question 7

If you are flying a multirotor and experience a sudden, strong updraft from a thermal, what is the expected initial reaction of the drone?

Accepted Answer

The drone will rapidly gain altitude; the flight controller will then reduce motor RPM to compensate and bring it back down to its target altitude

Answer

The drone will pitch forward

Answer

The drone will suddenly drop towards the ground

Answer

The drone will turn off completely

Question 8

Which cloud prefix indicates a 'Middle Cloud' (base typically between 6,500 and 20,000 ft)?

Accepted Answer

Alto- (e.g., Altostratus, Altocumulus)

Answer

Cirro-

Answer

Nimbo-

Answer

Strato-

Question 9

How is wind direction typically reported in aviation weather forecasts (such as METAR or TAF)?

Accepted Answer

In degrees True (from True North), indicating the direction the wind is blowing FROM

Answer

In degrees Magnetic, indicating the direction the wind is blowing TOWARDS

Answer

Using only cardinal points (N, S, E, W)

Answer

As a percentage of the Earth's rotation

Question 10

How does a high density altitude (e.g., a hot, humid day at a high elevation) affect the aerodynamic performance of a multirotor drone?

Accepted Answer

It decreases performance because the air is less dense, meaning the propellers generate less thrust and the motors must work harder

Answer

It increases performance because the warm air provides more lift

Answer

It has no effect on battery-powered drones

Answer

It cools the battery faster, extending flight time
