9.4 Summary
Flying an UAS is not without risk. In order to gain a good understanding of risk factors, several special factors are discussed below.
9.1.1 Interference
Interference constitutes disruptions to the radio controls of GNSS of a UAS, whether deliberate or not, by other systems. In some cases, control signals may be disrupted by other signals sent simultaneously on the same frequency, e.g. by radio towers and transformers.
9.1.2 War risk
