True

Question 15

It does not affect any system if the unmanned aerial vehicle only has limited or no access to GPS coverage. (T/F)

Answer 15

False

Question 16

In the event that the operation is performed by more than just the remote pilot, for example together with a sensor operator or observer, it is important that everyone can communicate uninterrupted with each other. (T/F)

Answer 22

True

Question 23

If you are surprised by strong winds, it is often a good idea to:
