Strictly controlled or postponed if the safety distances and exposure cannot be managed

Answer

Treated the same as an empty area

Answer

Carried out only in sport mode

Answer

Carried out without informing anyone beforehand

Question 5

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

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

When the site does not allow the A2 safety distances to be maintained, the best decision is:

Accepted Answer

to change location, wait, or call off the operation

Answer

to proceed anyway, simply at a greater height

Answer

to fly closer in order to finish quickly

Answer

to ask uninvolved persons not to look at the UAS

Question 7

If uninvolved persons enter the intended operational volume, the remote pilot must:

Accepted Answer

adjust or abort the flight to re-establish a safe distance

Answer

continue unchanged, provided the battery is sufficient

Answer

descend over them in order to finish the mission faster

Answer

disable the automatic return-to-home function

Question 8

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 9

When the UAS is fitted with a device that limits the consequences of an impact, such as a parachute, the remote pilot must regard it as:

Accepted Answer

an additional aid that does not replace the required safety distances.

Answer

a means that permits flight over an assembly of people.

Answer

an automatic clearance to operate in a restricted geographical zone.

Answer

a device that makes any flight preparation unnecessary.

Question 10

If the density of people increases during the mission, what is the correct decision?

Accepted Answer

Reassess the ground risk and, if necessary, adapt or terminate the flight

Answer

Continue the mission, since the original assessment always remains valid

Answer

Reduce the safety distance only, to save time

Answer

Fly faster to finish before the crowd arrives

Question 11

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 12

A UAS-zone map or app should be used:

Accepted Answer

with up-to-date data and complemented by actual observation of the site

Answer

only once, when the drone is purchased

Answer

only after an incident has occurred

Answer

as a substitute for all A2 'open' subcategory rules

Question 13

Temporary ground marking can be used to:

Accepted Answer

mark the limits of the working area and prevent people from entering it

Answer

allow flight in a control zone (CTR) without any conditions

Answer

increase the transmitter power

Answer

permanently turn a public area into a prohibited zone

Question 14

A sound operational mitigation measure consists of:

Accepted Answer

establishing a buffer zone between the flight path and the uninvolved persons

Answer

disregarding nearby transport routes

Answer

reducing the preparation in order to lower stress

Answer

flying over uninvolved persons when the flight is short

Question 15

The ground risk buffer must be adapted primarily to:

Accepted Answer

the type of UAS, the height, the speed and the surrounding environment

Answer

the brand of the mobile phone in use

Answer

the resolution of the camera

Answer

the number of photos planned for the mission

Question 16

Strong wind increases the ground risk in A2 because it:

Accepted Answer

can drift the UAS towards people or lengthen the stopping distance

Answer

reduces the mass of the UAS

Answer

cancels the minimum safety distances

Answer

makes the low-speed mode mandatory in all cases

Question 17

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

Question 18

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 19

Why should the manufacturer's user manual of a class C2 UAS be consulted?

Accepted Answer

Because it states the operational limitations and the safety functions available

Answer

Because it lists the customs rules applicable to batteries

Answer

Because it gives the opening hours of aerodromes

Answer

Because it classifies all airspace

Question 20

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 21

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 22

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 23

An aerial photography or filming mission in the A2 subcategory should favour:

angles and distances that achieve the desired result without reducing the safety distances

Answer

the lowest possible overflight of people

Answer

constantly flying at maximum speed

Answer

switching off the warnings

Question 24

Before an A2 flight in a busy environment, the most effective operational measure is to:

select a clear area, plan a safe flight path and provide for an abort of the flight.

Answer

take off immediately in order to shorten the flight time.

Answer

switch off the geo-awareness warnings.

Answer

move closer to the people to keep better control of the UAS.

Question 25

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 26

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 27

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 28

Answer

only the focal length of the camera

Answer

the colour of the airframe
