In the absence of reliable information about visibility, what is the recommended action before operating a sUAS?

• A. Proceed with best judgement
• B. Rely on unverified information
• C. Delay operation until reliable information is available
• D. Fly at a reduced altitude regardless of visibility

Answer: (C)

When visibility information isn’t reliable, you must not fly. Safe sUAS operation depends on being able to see the aircraft and detect obstacles, other aircraft, and terrain. Without dependable visibility data, you can’t accurately judge risk or distance, so delaying the flight until trusted information becomes available is the prudent choice. Proceeding based on guesswork or unverified reports increases the chance of collisions or loss of the aircraft, and simply flying at a lower altitude does not remove the fundamental hazard of uncertain visibility. Waiting for reliable information ensures you can plan and execute a safe flight.
