Technical and operational mitigations for ground risk - EASA Drone License A2

Question 1

In the A2 'open' subcategory, the 30 m figure corresponds to:

Accepted Answer

the standard minimum horizontal distance to be kept from uninvolved persons

Answer

the maximum permitted height in the 'open' category

Answer

the minimum distance from any industrial building

Answer

the minimum range of the remote controller

Question 2

How does a pre-flight inspection of the propellers help reduce the ground risk?

Accepted Answer

It can reveal a crack, incorrect fitting or wear that could lead to a loss of control

Answer

It reveals the exact orientation of the isobars

Answer

It confirms the validity of the medical certificate

Answer

It provides the telephone number of the authority

Question 3

If a person asks to cross the operational area, the remote pilot should:

Accepted Answer

Bring the UAS to a safe hold or land it before letting the person pass

Answer

Ask them to walk quickly underneath the UAS

Answer

Increase speed to finish the shot before they arrive

Answer

Ignore the request as long as the UAS is stable

Question 4

The low-speed mode available on some class C2 UAS is useful because it:

Accepted Answer

reduces the kinetic energy and makes it easier to keep safe distances

Answer

replaces any risk assessment

Answer

permits flight over an assembly of people

Answer

increases the impact energy

Question 5

Which check best reduces the ground risk before defining an operating area in A2?

Accepted Answer

Making sure that uninvolved persons can be avoided throughout the whole operation.

Answer

Checking only that the camera is working.

Answer

Choosing the nearest area, even if it is crowded.

Answer

Increasing the height to compensate for the presence of people.

Question 6

Which of the following is an example of a technical mitigation of the ground risk?

Accepted Answer

A system that limits the maximum speed or the kinetic energy on impact

Answer

Flying closer to uninvolved persons

Answer

Disabling the on-board warnings and alerts

Answer

Deliberately flying below the required safety distances

Question 7

Why must the automatic return-to-home function be configured carefully?

Accepted Answer

To prevent the UAS from returning over a crowded area or an obstacle

Answer

To increase the maximum speed allowed in the A2 subcategory

Answer

To cancel any minimum safety distance

Answer

To convert a class C2 UAS into a class C1 UAS

Question 8

A sound operational mitigation to apply before take-off is to:

Accepted Answer

plan a flight path that avoids pedestrian walkways

Answer

fly as close as possible to public access points

Answer

select an area without taking the wind into account

Answer

rely solely on the camera zoom to monitor the surroundings

Question 9

In the A2 'open' subcategory, flying over a built-up area is acceptable only if:

Accepted Answer

the safety distances from uninvolved persons and the local restrictions are still respected

Answer

the drone records in high resolution

Answer

the operation lasts less than five minutes

Answer

the UAS is launched by hand

Question 10

The most effective way to reduce the consequences of a ground impact is often to:

Accepted Answer

reduce the kinetic energy by managing mass, speed and distance to uninvolved persons

Answer

remove every area restriction

Answer

increase the flight altitude as much as possible

Answer

fly faster when close to people
