Color blindness causing red and green lights to merge

Question 5

During a clear, calm night in a mountainous area, how does the local wind typically behave?

Accepted Answer

Cold, dense air flows down the mountain slopes into the valleys (katabatic or mountain breeze)

Answer

Warm air rushes up the slopes from the valleys (anabatic breeze)

Answer

The wind blows perfectly horizontal to the peaks

Answer

There is a complete vacuum of air

Question 6

When must the ground risk assessment be carried out?

Accepted Answer

Before the flight, and updated during the flight if conditions change

Answer

Only after landing

Answer

Only when the UAS exceeds 25 kg

Answer

Only in the 'specific' category

Question 7

When assessing the ground risk, the factors to be taken into account include in particular:

Accepted Answer

the mass of the UAS, its speed and the density of people on the ground

Answer

the number of GNSS satellites alone

Answer

only the class of airspace

Answer

only the battery endurance

Question 8

Direct remote identification contributes to overall safety because it:

Accepted Answer

helps authorised persons identify the UAS and its operator

Answer

permits flight over an assembly of people

Answer

makes mission preparation unnecessary

Answer

physically reduces the kinetic energy of an impact

Question 9

The remote pilot must manage workload effectively in order to:

Accepted Answer

keep monitoring the UAS, the people and the surrounding environment

Answer

let the camera decide the flight path

Answer

fly relying only on the screen

Answer

ignore external interruptions

Question 10

Landing should be initiated early when the area becomes more crowded, in order to:

avoid reaching a situation where the only remaining option would endanger uninvolved persons

Answer

keep the full battery charge until automatic shutdown

Answer

avoid having to consult the user manual

Answer

keep the UAS hovering above the public

Question 11

If a payload is attached so that the Centre of Gravity (CG) is shifted significantly forward (nose-heavy), how will the UAS react?

Accepted Answer

The front motors will have to work much harder to maintain a level hover, reducing efficiency and potentially causing instability

Answer

The drone will automatically increase its maximum speed limit

Answer

The battery life will double due to aerodynamic momentum

Answer

The rear motors will overheat while the front motors shut down

Question 12

Accepted Answer

5 years

Answer

1 year

2 years

Answer

It is valid indefinitely for the lifetime of the pilot

Question 13

If you are involved in a drone incident that results in serious injury to a person or fatal damage to a manned aircraft, what are you legally required to do?

Accepted Answer

Report the occurrence immediately to the relevant national aviation/safety investigation authority and emergency services

Answer

Delete the SD card footage to protect your privacy

Answer

Pack up the drone and leave the area quietly

Answer

Post the video on social media to warn others

Question 14

An area with nearby cables, branches or masts requires:

Accepted Answer

a flight path with additional lateral and vertical safety distances

Answer

an automatic increase in speed

Answer

flight without direct visual line of sight

Answer

deliberately overflying people to avoid the obstacles

Question 15

In meteorology, 'Convection' refers to:

Accepted Answer

The vertical transport of heat in the atmosphere, often causing warm, less dense air to rise and form thermals or cumulus clouds

Answer

The horizontal movement of air across the surface

Answer

The freezing of supercooled water droplets in a cloud

Answer

The deflection of wind by the Earth's rotation

Question 16

Checking the wind direction before take-off helps to:

Accepted Answer

position the flight path and the contingency areas while accounting for possible drift

Answer

choose the colour of the propellers

Answer

disable the height limitations

Answer

replace the safety distances from uninvolved persons

Question 17

A pre-flight briefing contributes to risk reduction because it:

Accepted Answer

aligns everyone involved on the operating area, the signals and the emergency procedures

Answer

makes checking the weather unnecessary

Answer

replaces the pre-flight inspection of the UAS

Answer

allows the 120 m height limit to be exceeded

Question 18

Why is it crucial to respect the Centre of Gravity (CG) limits specified by the UAS manufacturer?

Accepted Answer

To prevent overloading specific motors and maintain aerodynamic stability and control

Answer

It is completely irrelevant due to the automatic compensation of modern ESCs

Answer

The CG must always be positioned exactly on the front right propeller

Answer

It only affects the drone during the landing phase

Question 19

What is the primary purpose of the 'Specific Operations Risk Assessment' (SORA) in EASA regulations?

Answer

Is highly efficient and glides easily

Answer

Answer

The lifting of a drone's nose by adjusting the front propellers

Answer

The lifting of fog by the morning sun

Answer

The air pushed upwards by a heavy jet taking off

Question 28

During an A2 operation, the presence of obstacles on the ground can be useful when it:

Accepted Answer

helps to naturally keep people separated from the intended flight path

Answer

forces the UAS to fly with no safety margin

Answer

completely hides the UAS from the remote pilot

Answer

removes the need to keep uninvolved persons under observation

Question 29

What happens if you fly a multirotor drone into a very low-pressure environment (e.g., high mountain altitude)?

Accepted Answer

The air is less dense, so the propellers must spin faster to generate the same amount of lift, resulting in reduced thrust capability and shorter battery life

Answer

The drone will fly significantly faster

Answer

The battery life will double

Answer

The drone's compass will reverse its polarity
