AC 107-2A's sample risk assessment identifies a hazard of 'loss of control link over people.' Which of the following is listed as a cause of this hazard?
Why: AC 107-2A Appendix A's sample risk assessment table lists the causes of a loss of control link as loss of power supply from the control station, the small UA going out of range, or signal interference from another device (such as Wi-Fi or Bluetooth).
Describes a required safety practice, not a hazard cause; a preflight briefing reduces risk rather than causing control-link loss.
Describes a routine, compliant altitude; flying below 400 feet AGL is not identified as a cause of control-link loss in the AC's example.
