Question 1

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 2

In aviation, what does 'RVR' stand for?

Accepted Answer

Runway Visual Range; the horizontal distance a pilot on the centre line of a runway can see the runway surface markings or lights

Answer

Radar Vector Routing

Answer

Relative Velocity Ratio

Answer

Rapid Vertical Rise

Question 3

According to the International Standard Atmosphere (ISA), what is the standard atmospheric pressure at mean sea level?

Accepted Answer

1013.25 hPa

Answer

1000.00 hPa

Answer

1025.13 hPa

Answer

995.50 hPa

Question 4

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 5

For standard aviation weather reporting (METAR), at what height above the ground is wind speed and direction officially measured by an anemometer?

Accepted Answer

10 metres (approx. 33 feet)

Answer

1 metre

Answer

50 metres

Answer

100 metres

Question 6

What is the standard temperature lapse rate in the troposphere under ISA conditions?

Accepted Answer

It decreases by approximately 2.0 °C per 1,000 feet (or 6.5 °C per 1,000 metres) of altitude gained

Answer

It increases by 1 °C for every 100 metres of altitude

Answer

It remains completely constant up to 30,000 feet

Answer

It drops by exactly 10 °C per 1,000 feet

Question 7

Why is a Katabatic wind often much stronger than an Anabatic wind?

Accepted Answer

Because katabatic winds (cold, dense air draining downslope) are assisted by gravity, making them accelerate and often become quite strong

Answer

Because the sun is hotter in the afternoon

Answer

Because they only happen near the equator

Answer

Because they are driven by the Coriolis effect

Question 8

The 'friction layer' (or planetary boundary layer), where surface friction significantly slows the wind and causes turbulence, usually extends from the surface up to about:

Accepted Answer

2,000 to 3,000 feet (approx. 600 to 900 metres)

Answer

50 feet (15 metres)

Answer

30,000 feet

Answer

100,000 feet

Question 9

What is the definition of 'True Altitude'?

Accepted Answer

The exact vertical distance of the aircraft above Mean Sea Level (MSL)

Answer

The exact vertical distance of the aircraft above the ground directly below it (AGL)

Answer

The altitude read on the controller when the drone is turned on

Answer

The altitude based on standard atmospheric pressure (1013.25 hPa)

Question 10

What is the primary danger of operating a UAS near the anvil of a cumulonimbus cloud?

Accepted Answer

Severe turbulence, lightning, and large hail can be thrown out of the anvil and fall miles away from the main storm centre

Answer

The anvil blocks GPS satellites

Answer

It makes the drone invisible to radar

Answer

The air is too thin to fly in
