In relation to UAS preflight operations, a "FRAT" is a _____.

• A. Flight risk analysis tool
• B. Flight readiness assessment tool
• C. Flight routine and timing
• D. Final route and terrain

Answer: (A)

During preflight UAS operations, you use a structured method to assess the mission’s risk: a Flight Risk Analysis Tool. This tool guides you to consider factors that could raise the chance of an incident—weather, airspace restrictions, terrain and visibility, time of day, pilot experience and training, aircraft maintenance status, battery and payload concerns, and what you’d do if something goes wrong. You evaluate each factor, assign a risk level, and then apply mitigations to bring the overall risk to an acceptable level. The aim is to identify hazards before takeoff and make a go/no-go decision based on a quantified risk picture. The other options describe readiness, routine and timing, or route and terrain specifics, which aren’t what FRAT specifically analyzes.
