Which factor can contribute to workload even with high automation?

• A. FMS programming and verification tasks.
• B. Reduced attention due to automation lowering workload.
• C. Less need for coordination.
• D. Automation eliminates errors.

Answer: (A)

Even with high automation, workload can stay and even rise because of the need to manage data entry and verification for the flight management system. FMS programming involves inputting the flight plan, performance targets (like speeds, altitudes, and fuel), routes, constraints, and wind/temperature data. This is meticulous work where small mistakes can ripple through the system, so thorough verification is essential—checking that the planned route, performance data, and fuel calculations match charts, weather information, and ATC clearances.

As changes occur before or during the flight, reprogramming or updating the FMS and its VNAV/flight path profiles becomes an ongoing task, demanding attention and cross-checking. This cognitive workload persists even when automation handles much of the flight path, because the data management, validation, and re-planning duties remain.

Other options would imply that automation reduces workload or eliminates errors, which isn’t accurate. While automation can reduce manual tasks, the process of programming and verifying the FMS introduces a substantial and continuous workload that must be managed to ensure safe, efficient operations.
