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

Question 1

The remote pilot must limit the time spent close to uninvolved persons in order to:

Accepted Answer

Reduce the time of exposure to the risk

Answer

Increase the temperature of the batteries

Answer

Make a direct overflight easier

Answer

Eliminate the lateral safety distances

Question 2

Checking the wind direction before take-off helps to:

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 3

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

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

Question 4

Hovering for a long time over a public access point is not advisable because:

it increases the exposure time of the people passing below or close to the UAS

Answer

it always reduces power consumption

Answer

it eliminates any risk of failure

Answer

it replaces the ground safety area

Question 5

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

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 6

To limit the ground risk, it is sound practice to:

Accepted Answer

plan a flight path that avoids areas occupied by uninvolved persons

Answer

fly as close to people as possible to keep them in sight

Answer

fly over roads in order to have a clear corridor available

Answer

use only the FPV camera with no observer

Question 7

Direct remote identification contributes to overall safety because it:

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 8

In the A2 'open' subcategory, how can the presence of an assistant support the operation?

Accepted Answer

By monitoring people or vehicles approaching the edges of the operating area

Answer

By allowing the flight to be conducted outside the 'open' category

Answer

By taking over the remote pilot's responsibility

Answer

By controlling the UAS without any coordination

Question 9

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 10

Before an A2 flight, the remote pilot must in particular:

assess the operating area and the presence of uninvolved persons

Answer

fly without any prior preparation

Answer

assume that subcategory A2 allows flight over an assembly of people

Answer

disregard the speed of the UAS

Question 11

The operation's documentation must, as a minimum, include:

Accepted Answer

the intended operating areas, the identified risks and the chosen mitigation measures

Answer

only the commercial name of the UAS

Answer

only the number of photos expected

Answer

a general authorisation valid everywhere

Question 12

Recovering the UAS after landing must be organised so that:

Accepted Answer

Uninvolved persons are kept away from the propellers and from a possibly damaged battery

Answer

The motors remain armed until the aircraft is packed away

Answer

The UAS is left lying in the middle of a walkway

Answer

The aircraft is relaunched after any impact without a fresh check

Question 13

The presence of animals or vulnerable persons in the area should lead the remote pilot to:

Accepted Answer

increase the safety distances or postpone the flight if the risk becomes too high

Answer

fly lower to reassure them

Answer

ignore their presence, because A2 allows it

Answer

switch off the remote identification

Question 14

The remote pilot reduces risk by keeping a time margin because it:

Accepted Answer

makes it possible to wait for people to pass before continuing along a flight path

Answer

means the operation must always finish before the client expects

Answer

allows flying faster when the battery is low

Answer

removes the need for any contingency plan

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

The presence of remote identification or a geo-awareness function:

Accepted Answer

can contribute to safety but does not replace the operational risk assessment

Answer

overrides the legal restrictions

Answer

automatically authorises any flight close to uninvolved persons

Answer

removes all responsibility from the remote pilot

Question 17

An unexpected gust near obstacles should lead the remote pilot to:

Accepted Answer

increase the safety distances or abort the mission if control becomes uncertain

Answer

move closer to the facades for shelter

Answer

fly closer to people to see better

Answer

switch off the wind warnings

Question 18

Choosing a moderate speed during the operation mainly allows the remote pilot to:

Accepted Answer

reduce the kinetic energy and increase the available reaction time

Answer

exceed the maximum height limit

Answer

eliminate turbulence

Answer

dispense with the A2 certificate of competency

Question 19

An emergency landing should preferably be directed towards:

Accepted Answer

an area clear of people, vehicles and hazardous obstacles

Answer

the area that is most visible to the public

Answer

a busy footpath

Answer

the vertical directly above the remote pilot, without looking around

Question 20

Following an impact or a hard landing, the correct action is to:

Accepted Answer

Inspect the UAS before any further flight

Answer

Take off again immediately if the camera still works

Answer

Switch off the flight logs

Answer

Disregard the event if no public is present

Question 21

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

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
