measure the wind speed at ground level

Answer

replace direct visual observation of the UAS

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

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

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 8

Using a ground observer is useful when:

it allows flying without holding the A2 certificate of competency

Answer

it permits flying behind a building, out of sight

it removes the applicable airspace restrictions

Question 9

In the event of a loss of control near uninvolved persons, the priority must be to:

apply the planned emergency procedure and reduce the exposure of uninvolved persons

Answer

continue the mission in order to finish it quickly

Answer

gain altitude above the people

Answer

simply switch off the video recording

Question 10

Temporary ground marking can be used to:

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 11

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

Accepted Answer

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 12

Good communication with the client or the ground crew mainly serves to:

Accepted Answer

prevent unexpected movements within the controlled ground area

Answer

increase the maximum speed of the UAS

Answer

replace the remote pilot's competency requirement

Answer

permit flight over an assembly of people

Question 13

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 14

An automated waypoint flight must still be monitored because:

Accepted Answer

the actual environment may change and require manual intervention

Answer

it transfers responsibility to the software

Answer

it permits overflying uninvolved persons

Answer

it prohibits any interruption of the flight

Question 15

The emergency motor cut-off should only be used when:

Accepted Answer

it reduces the overall risk compared with continuing the flight

Answer

the video image is not stable enough

Answer

the remote pilot wants to save battery

Answer

the UAS is positioned over an assembly of people

Question 16

The low-speed mode of a class C2 UAS is useful because it:

Accepted Answer

reduces the maximum horizontal speed, and therefore the potential energy of an impact.

Answer

automatically increases the maximum take-off mass (MTOM).

Answer

allows flight beyond visual line of sight without an observer.

Answer

replaces the registration of the operator.

Question 17

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 18

What does clearly briefing the people present on site help to achieve?

Accepted Answer

It reduces unintended entries into the operational area

Answer

It permits overflight of an assembly of people

Answer

It overrides the required safety distances

Answer

It makes any weather assessment unnecessary

Question 19

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

Accepted Answer

the mass, the speed, the height and the available safety functions.

Answer

the colour of the navigation lights.

Answer

the transmit power of the radio link alone.

Answer

the number of satellites acquired at take-off.

Question 20

Before activating an automatic flight path, the remote pilot must verify:

Answer

fly faster when close to people

Question 27
