Identify one factor that can lead to loss of control of a UAS.

Signal interference or poor battery performance is indeed a significant factor that can lead to a loss of control of a UAS. Signal interference can occur due to various sources, including other electronic devices, physical obstacles, or environmental conditions that disrupt the communication link between the UAS and the pilot’s controller. This disruption can result in latency, loss of control, or even the inability to receive telemetry data from the UAS, affecting the pilot's situational awareness and decision-making.

Additionally, poor battery performance can lead to diminished power supply, ultimately affecting the UAS's ability to maintain altitude, maneuver, or even return to home safely. If the battery level drops too low, it may trigger emergency protocols or a loss of control altogether.

In contrast, high altitude navigation typically does not lead to loss of control as long as the UAS is within its operating parameters and the pilot is aware of airspace regulations. Established flight paths should enhance safety rather than compromise it, as they provide predictable operational patterns. Although firmware updates can introduce new features or improvements, they usually do not directly cause control loss unless there are specific bugs or failures, which would typically be resolved through testing prior to deployment.
