Emergency Procedures

This section provides checklists and procedures for coping with emergencies that may arise during sUAS operations. Malfunctions are rare, especially if proper pre-flight inspections and maintenance are practiced. Weather emergencies may be minimized by careful flight planning and sound judgment; however, sUAS pilots should be ready to respond to rapidly changing weather conditions. Should an emergency arise, the guidelines in this section should be considered and applied as necessary to correct problems.

In case of interference or other communications issues, the GCS will alert with a lost connection annunciation. The following procedures should be followed if no RTL is observed.

If the sUAS loses signal from the radio link, the aircraft will go into RTL mode. In this mode, the following procedures should be followed.

Actions to be Performed
