When is it recommended to accomplish FMS programming?

• A. During the briefing
• B. Before the briefing
• C. After the briefing
• D. During the flight

Answer: (B)

FMS programming should be completed before the briefing because having the route, performance data, nav data, and other inputs loaded and verified ahead of time lets the crew review and discuss the plan without being tied up with data entry. This makes the briefing focused on validating the plan, weather, fuel, contingencies, and ATC clearances, rather than scrambling to input information. Doing the work during the briefing would split attention and hinder a smooth, safety-focused discussion. Doing it during the flight adds unnecessary workload and can violate sterile cockpit discipline during critical phases. Preparing the FMS beforehand keeps the briefing productive and the overall workflow safer and more efficient.
