In-Flight Emergencies

Deviations of regular control behavior can be provoked e.g. by other transmitters in
close proximity of the UAV. They can disturb the video signal (5.8 GHz frequency band),
the data link connection (2.4 GHz frequency band) and/or the GNSS module or other
system electronics.
In some cases malfunctions or electronic component failures can also lead to an
abnormal behavior of the UAV.
Situations, which may appear and how to react in these cases, are described in the
following section.
