Contingency planning in UAS operations includes a plan for what to do when communications are lost.

• A. Emergency landing script
• B. Maintenance contingency plan
• C. Redundancy checklist
• D. Lost communications flight plan

Answer: (D)

Contingency planning for a UAS includes a defined response when contact with the aircraft is lost. The best choice is a lost communications flight plan because it provides a preloaded set of instructions the drone will follow automatically if the link to the operator is broken. This plan specifies actions like continuing to a preplanned route, returning to home, or landing at a safe, designated location, along with the required altitude and timing. This ensures a predictable, safe outcome without needing immediate manual control. Other options address different safety aspects—an emergency landing script is a specific landing cue, a redundancy checklist focuses on hardware/software backups, and a maintenance contingency plan deals with upkeep and replacements—none directly establish the automatic actions the aircraft should take during a comms outage.
