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

Question 1

When a low-battery warning is triggered, the safest response is to:

return or land according to the planned procedure before the reserve is used up

Answer

continue flying until the automatic shutdown occurs

Answer

accelerate over people to finish sooner

Answer

ignore the warning as long as the video image stays stable

Question 2

What is the main purpose of establishing a ground risk buffer around the operational area?

Accepted Answer

To absorb deviations from the intended flight path without immediately endangering uninvolved persons

Answer

To replace the A2 'open' subcategory remote pilot certificate

Answer

To increase the permitted MTOM of the UAS

Answer

To remove the need for a spare battery

Question 3

An automated waypoint flight must still be monitored because:

it transfers responsibility to the software

Answer

it permits overflying uninvolved persons

Answer

it prohibits any interruption of the flight

Question 4

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 5

The so-called 1:1 rule states that the remote pilot should generally keep a horizontal distance at least equal to:

Accepted Answer

the height of the UAS above the ground.

Answer

the length of the nearest runway.

Answer

the distance covered in one minute.

Answer

the maximum range of the radio link.

Question 6

How does checking the battery state of charge contribute to reducing the ground risk?

Accepted Answer

It helps prevent an unexpected loss of power over a sensitive area

Answer

It automatically authorises flight in a restricted area

Answer

It replaces the weather check

Answer

It permits overflight of uninvolved persons

Question 7

The flight height affects the ground risk because it:

Accepted Answer

increases the time to fall and can enlarge the possible impact area

Answer

always reduces drift caused by the wind

Answer

removes the need for horizontal safety distances

Answer

prevents any kind of technical failure

Question 8

When an alternative diversion route is planned, it should preferably lead to:

Accepted Answer

an open area that poses less risk to uninvolved persons

Answer

the busiest point, to make recovery of the UAS easier

Answer

a restricted zone, in order to avoid obstacles

Answer

a heavily used traffic route

Question 9

Tracking a moving subject in the A2 subcategory must be declined or adapted when:

Accepted Answer

it would lead the UAS to approach uninvolved persons without maintaining an adequate safety distance

Answer

the subject is wearing dark clothing

Answer

the camera is fitted with an optical zoom

Answer

the memory card in the aircraft is empty

Question 10

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 11

The main purpose of the geo-awareness function is to:

Accepted Answer

alert the remote pilot to the geographical restrictions applicable to the operation

Answer

predict the temperature of the battery

Answer

measure the wind speed at ground level

Answer

replace direct visual observation of the UAS

Question 12

A correctly set height limiter allows the remote pilot to:

Accepted Answer

stay within the applicable height limit and keep a consistent vertical safety margin

Answer

waive the horizontal safety distances required in A2

Answer

fly without keeping the UAS in direct visual line of sight

Answer

increase the maximum take-off mass that is allowed

Question 13

An assembly of people represents a particular hazard because:

Accepted Answer

no flight path can be guaranteed without putting uninvolved persons at risk

Answer

it reduces the MTOM of the UAS

Answer

it makes the low-speed mode unnecessary

Answer

it allows the UAS to be flown directly over the crowd

Question 14

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 15

Reflection of the GNSS signal in an urban environment can:

Accepted Answer

degrade position hold and increase the risk of drift

Answer

always improve the accuracy

Answer

replace reading the map

Answer

remove the maximum height limit

Question 16

Propeller guards can reduce certain risks, but they must not be regarded as:

Accepted Answer

an authorisation to make deliberate contact with people

Answer

a mechanical aid that may be available depending on the UAS

Answer

an item to be checked before flight whenever they are fitted

Answer

a means of limiting certain minor injuries

Question 17

Continuous observation of the surroundings serves in particular to:

Accepted Answer

detect uninvolved persons arriving and adapt the mission accordingly

Answer

replace the need to check the UAS geographical zones

Answer

automatically extend the battery endurance

Answer

allow flight above 120 m

Question 18

Rain can increase the ground risk in particular because it:

Accepted Answer

can degrade visibility, the sensors or the performance of the UAS

Answer

always reduces the kinetic energy on impact

Answer

makes uninvolved persons legally invisible

Answer

permits flight over an assembly of people

Question 19

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 20

Checking the published UAS geographical zones before flight allows the remote pilot to:

Accepted Answer

identify restrictions that may impose stricter conditions

Answer

replace the assessment of people on the ground

Answer

raise the European 120 m height limit

Answer

remove the requirement to register as an operator

Question 21

Keeping a logbook or incident report is useful because it:

Accepted Answer

Helps identify the causes and improve the mitigation measures

Answer

Replaces the pre-flight checks

Answer

Increases the range of the command-and-control link

Answer

Authorises flight in any geographical area

Question 22

In the 'open' category A2, limiting the energy delivered on impact mainly depends on:

Answer

Eliminate the lateral safety distances

Answer

select an area without taking the wind into account

Answer

Answer

Because it increases the capacity of the battery
