What must a Remote PIC do if their control station loses communication with the sUAS?

When a Remote Pilot in Command (Remote PIC) encounters a loss of communication with the small Unmanned Aircraft System (sUAS), executing a return home protocol is the appropriate action to take. This protocol is designed as a safety feature to help ensure that the sUAS can autonomously navigate back to a predetermined location, typically the takeoff point, in the event of communication loss.

The importance of this protocol lies in its ability to minimize the risk of the sUAS wandering off-course or potentially causing harm to people or property in the airspace. It is a contingency measure that enhances safety by ensuring that the sUAS can be controlled through autonomous functions even if remote communication is interrupted.

Other actions, such as immediately landing the sUAS, can be less effective in preventing an uncontrolled flight. In some situations, an immediate landing may lead to hazards if the sUAS descends unpredictably. Waiting for re-establishment of communication might not be practical, especially if the loss of signal is prolonged, and the position of the sUAS may remain uncertain during that time. Notifying local law enforcement would not address the immediate safety concerns presented by the lost communication. Thus, executing a return home protocol is the most responsible
