Answer

only the commercial name of the UAS

Answer

only the number of photos expected

Answer

a general authorisation valid everywhere

Question 10

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

30 m.

Answer

5 m in all cases.

Answer

10 m, with no further condition.

Answer

150 m, as in A3.

Question 12

The choice of the take-off and landing site must, above all, make it possible to:

Accepted Answer

limit the exposure of uninvolved persons during the critical phases of flight

Answer

increase the speed during the approach

Answer

maximise proximity to the public

Answer

avoid keeping any safety distance

Question 13

A heavier UAS generally requires:

Accepted Answer

larger safety distances because of the potential kinetic energy of an impact

Answer

smaller distances because it is more stable

Answer

no additional check

Answer

flying over people as a matter of routine

Question 14

A flight near a busy road must be prepared so that:

Accepted Answer

a loss of control would not endanger the road users

Answer

the airflow from the vehicles can be used to advantage

Answer

a better mobile network connection is obtained

Answer

overflying the vehicles is made easier

Question 15

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 16

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 17

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 18

The fail-safe behaviour must be tested or checked before flight because it:

Accepted Answer

determines how the UAS behaves on loss of signal or a critical problem

Answer

indicates the local atmospheric pressure

Answer

guarantees calm wind conditions

Answer

replaces the operator's insurance

Question 19

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 20

The horizontal speed must be adapted when operating near people because:

Accepted Answer

it directly affects the distance covered during the remote pilot's reaction time

Answer

it has no influence at all on the kinetic energy of an impact

Answer

it replaces the requirement to keep the UAS within visual line of sight (VLOS)

Answer

it allows the flight to be carried out without any clear area below

Question 21

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 22

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