What can terrain masking, equipment failures, and electromagnetic interference lead to in flight operations?

Terrain masking, equipment failures, and electromagnetic interference are all factors that can adversely affect the performance of Unmanned Aircraft Systems (UAS) during flight operations. When we discuss "loss of link," we are referring to the situation where the communication between the UAS and the ground control station becomes interrupted or completely lost.

Terrain masking occurs when the UAS is obscured by a physical obstacle, such as a hill or building, which can block or degrade the transmission of signals. Similarly, equipment failures can lead to a breakdown in communication components, making it difficult or impossible to maintain control over the UAS. Electromagnetic interference involves disruption caused by radio frequency signals from other devices, which can also interfere with the UAS's ability to receive commands or send telemetry data back to the operator.

In each of these scenarios, the UAS is at a high risk of losing the connection between the aircraft and the operator, compromising its control and potentially leading to unsafe situations during flight. Thus, understanding the implications of these issues is critical for ensuring safe and effective UAS operations.
