Exam quiz EASA Drone Quiz A2

Question 1

When should a remote pilot prioritize a new compass (magnetometer) calibration even if the flight controller software does not explicitly request it?

Accepted Answer

When moving the operation to a significantly different geographical location (e.g., more than 50-100 km from the last site)

Answer

Every time the battery is replaced during a single mission

Answer

Only when flying indoors

Answer

After every firmware update of the camera gimbal

Question 2

According to EASA, what is the legal difference between a 'UAS Operator' and a 'Remote Pilot'?

Accepted Answer

The UAS Operator is the individual or organization registered and responsible for the drone's maintenance and compliance; the Remote Pilot is the person physically controlling the drone during flight

Answer

The operator flies the drone, while the pilot only monitors the camera

Answer

They are exactly the same thing and the terms can be used interchangeably

Answer

The UAS Operator is always a commercial company, while the Remote Pilot is always a hobbyist

Question 3

Answer

Toy drones are painted in bright colors

Answer

Toy drones must weigh exactly 249 grams

Answer

There is no legal distinction; all drones are treated identically

Answer

It only occurs in the Earth's stratosphere

Answer

It is the term for a single thunderstorm cloud

Question 10

What is the primary cause of 'Mechanical Turbulence'?

Accepted Answer

Wind flowing over irregular terrain, buildings, or trees, causing the air to break into complex eddies and swirls

Answer

The drone's motors spinning out of sync

Answer

The sun heating the ground unevenly

Answer

Two air masses of different temperatures colliding

Question 11

May a remote pilot drop articles or carry dangerous goods under the Open A2 subcategory?

Accepted Answer

No, carrying dangerous goods and dropping articles are strictly prohibited in the entire Open category

Question 12

On the Beaufort scale, a Force 5 wind (Fresh Breeze, roughly 17-21 knots) is generally characterized on land by:

Answer

A deep, calm lake

Answer

A dense, green forest

Answer

The atmospheric pressure measured at the exact altitude of the drone

Answer

The standard pressure of 1013.25 hPa

Answer

The altitude above ground level (AGL)

Question 15

How does the 'Funneling Effect' (or Venturi Effect) alter the wind?

Accepted Answer

When wind is forced through a narrow space, like a mountain pass or between tall buildings, its velocity increases significantly

Answer

It makes the wind blow in circles

Answer

It cools the wind down to freezing temperatures

Answer

It completely stops the wind from moving

Question 16

In a METAR report, what does the descriptor 'SH' mean?

Accepted Answer

Showers (e.g., SHRA means Rain Showers)

Answer

Snow and Hail

Answer

Shallow Fog

Answer

Severe Hazard

Question 17

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 18

Answer

A steady, gentle sea breeze

Question 20

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 21

What happens if you fly from an area of high atmospheric pressure into an area of low pressure without updating your barometric altimeter?

Answer

It forces the drone to fly in a straight line
