Question 1

In the Northern Hemisphere, how does the wind flow around a High-Pressure system (Anticyclone) at the surface?

Accepted Answer

Clockwise and spiraling outward

Answer

Counter-clockwise and spiraling inward

Answer

Straight upwards

Answer

Parallel to the equator

Question 2

How do intense solar flares and geomagnetic storms (high Kp-index) primarily impact UAS operations?

Accepted Answer

They disrupt the Earth's ionosphere, causing severe GPS/GNSS positioning errors, loss of satellite lock, and compass interference

Answer

They cause the drone's plastic shell to melt

Answer

They create sudden thermal updrafts from the ground

Answer

They drain the LiPo battery in seconds

Question 3

Which cloud type is characterized as high-altitude, wispy, and composed entirely of ice crystals?

Accepted Answer

Cirrus

Answer

Stratus

Answer

Cumulus

Answer

Nimbostratus

Question 4

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 5

If a drone flies upward into a strong Temperature Inversion layer, what unexpected aerodynamic effect might occur?

Accepted Answer

The sudden encounter with warmer, less dense air can cause a noticeable decrease in lift and motor efficiency

Answer

The drone will freeze instantly

Answer

The drone's lift will double

Answer

The propellers will spin backwards

Question 6

How does the wind gradient affect a drone descending to land in windy conditions?

Accepted Answer

As the drone descends into slower air near the ground, its aerodynamic lift may suddenly decrease, requiring the pilot to apply more throttle to prevent a hard landing

Answer

The drone will experience a sudden increase in wind speed near the ground

Answer

The wind gradient will push the drone upwards

Answer

It causes the drone's compass to spin

Question 7

If you see the code 'OVC005' in a METAR, how high is the cloud ceiling?

Accepted Answer

500 feet Above Ground Level (AGL)

Answer

50 feet Above Ground Level (AGL)

Answer

5,000 feet Mean Sea Level (MSL)

Answer

5 miles high

Question 8

How does a low-level temperature inversion affect local weather and visibility near the ground?

Accepted Answer

It acts like a lid, trapping dust, smoke, smog, and moisture near the surface, often leading to very poor visibility and hazy conditions

Answer

It creates violent thunderstorms

Answer

It clears the air instantly, providing perfect visibility

Answer

It causes the wind to double in speed

Question 9

In a METAR, what does the code 'FG' indicate?

Accepted Answer

Fog (visibility is less than 1,000 metres)

Answer

Freezing Gusts

Answer

Fair Gusts

Answer

Falling Graupel

Question 10

Under what specific conditions does 'Upslope Fog' form, and why is it a significant hazard for drone pilots in hilly terrain?

Accepted Answer

It forms when moist, stable air is forced up rising terrain by the wind and cools adiabatically; it can persist even with strong winds, unlike radiation fog

Answer

It is caused by the sun heating the surface too quickly, creating a steam-like effect

Answer

It forms only in urban areas due to the high density of buildings and smog

Answer

It is formed by the cooling of the Earth's surface during a completely calm, clear night
