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 14

In the 'open' subcategory A2 with a class C2 UAS, the standard minimum horizontal distance to uninvolved persons is:

Accepted Answer

30 m.

Answer

5 m in all cases.

Answer

10 m, with no further condition.

Answer

150 m, as in A3.

Question 15

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 16

A secondary landing site should be selected:

Accepted Answer

before the flight and, where possible, located in a clear area free of uninvolved persons

Answer

only after a failure has already occurred

Answer

directly above a group of people

Answer

only when the UAS is a class C0 unmanned aircraft

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

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 19

A correctly set height limiter allows the remote pilot to:

Accepted Answer

stay within the applicable height limit and keep a consistent vertical safety margin

Answer

waive the horizontal safety distances required in A2

Answer

fly without keeping the UAS in direct visual line of sight

Answer

increase the maximum take-off mass that is allowed
