Exam quiz EASA Drone Quiz A2

Question 1

Why can a 'katabatic wind' be particularly dangerous for a drone pilot operating in a valley at night or early morning?

Accepted Answer

Because it is a sudden, downslope flow of cold, dense air that can significantly exceed the drone's wind resistance limits without warning

Answer

Because it carries warm air that can overheat the flight controller

Answer

Because it only blows upwards, making it impossible to land

Answer

Because it reverses the polarity of the GPS compass

Answer

A deep, calm lake

Answer

A dense, green forest

Answer

A snow-covered field

Question 4

Which of these is a 'Technical Mitigation' to reduce ground risk?

Accepted Answer

Installing an automated parachute recovery system on the drone

Answer

Checking the weather forecast online

Answer

Question 5

During the 'Dissipating Stage' of a thunderstorm, what air movement dominates?

Answer

Strong updrafts

Answer

Horizontal winds only

Answer

A perfect vacuum

Question 6

In a TAF (Terminal Aerodrome Forecast), what does the abbreviation 'BECMG' signify?

Update the firmware mid-flight via cellular connection

Answer

Firmware updates are illegal for C-class drones

Question 8

Which of the following best describes an 'Emergency Procedure' compared to a 'Contingency Procedure'?

Accepted Answer

A contingency procedure handles an abnormal situation to prevent it from escalating; an emergency procedure handles a critical situation where safety is immediately compromised (e.g., flyaway or motor failure)

Answer

Emergency procedures are used when the camera SD card is full

At altitudes exceeding 50 meters AGL

Answer

Only when flying over uneven mountainous terrain

Answer

When the wind speed exceeds 15 m/s

Question 12

Why is it dangerous to fly a drone behind a large, solid structure like a metal building?

Accepted Answer

It blocks both the radio control link (VLOS and telemetry) and the GPS satellite signals, highly increasing the risk of signal loss and a crash

Answer

The building will absorb the drone's battery charge

Answer

The drone will automatically initiate a landing procedure as soon as it sees a wall

Answer

It is not dangerous if the drone has obstacle avoidance sensors

Straight up into the stratosphere

Answer

In a perfect circle around the equator

Question 15

What is 'Aerodynamic Drag'?

Accepted Answer

The resistive force exerted by the air opposite to the direction of the aircraft's motion

Answer

The upward force generated by the propellers

Answer

The gravitational pull on the drone's mass

Answer

The rotational force around the yaw axis
