reducing the preparation in order to lower stress

Answer

flying over uninvolved persons when the flight is short

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 11

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 12

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 13

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 14

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 15

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 16

The presence of a prohibited or restricted zone should lead the remote pilot to:

Accepted Answer

comply with the published conditions, or refrain from flying if they cannot be met

Answer

simply fly lower without any further checks

Answer

switch off geo-awareness

Answer

rely only on an outdated screenshot

Question 17

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 18

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 19

In the A2 'open' subcategory, flying over a built-up area is acceptable only if:

Accepted Answer

the safety distances from uninvolved persons and the local restrictions are still respected

Answer

the drone records in high resolution

Answer

the operation lasts less than five minutes

Answer

the UAS is launched by hand

Question 20

The remote pilot must keep a battery reserve because:

Accepted Answer

a return or go-around may be needed to keep clear of uninvolved persons

Answer

the regulations always require a 90% charge at landing

Answer

the battery has no influence on the ground risk

Answer

it allows a tailwind to be ignored

Question 21

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

The UAS is left lying in the middle of a walkway

Answer

The aircraft is relaunched after any impact without a fresh check

Question 22

When assessing the ground risk, the factors to be taken into account include in particular:

the mass of the UAS, its speed and the density of people on the ground

Answer

the number of GNSS satellites alone

Answer

only the class of airspace

Answer

only the battery endurance

Question 23

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 24

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

keep monitoring the UAS, the people and the surrounding environment

Answer

let the camera decide the flight path

Answer

fly relying only on the screen

Answer

ignore external interruptions

Answer

exceed the maximum height limit

Answer

eliminate turbulence

Answer

dispense with the A2 certificate of competency

Question 27

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

Accepted Answer

that the waypoints keep clear of people, obstacles and sensitive areas

that the camera is pointed towards the sun

Answer

that the phone volume is set to maximum

Answer

that the UAS is no longer visible

Because a distraction can delay the remote pilot's reaction to uninvolved persons entering the area

Answer

Because it increases the capacity of the battery

Answer

Because it makes the wind negligible

Answer

Because it replaces the A2 'open' subcategory competency
