In which distance can the length of a stopway be included?

• A. In the take-off run available
• B. In the one engine failure case, take-off distance
• C. In the all engine take-off distance
• D. In the accelerate stop distance available

Answer: (D)

The length of a stopway can be included in the accelerate stop distance available, which is the correct answer. This dimension is specifically designed to provide an additional area of runway beyond the runway threshold to allow for a safe abort of takeoff if necessary. When calculating accelerate stop distance available, it encompasses the distance needed to reach the decision speed and then stop safely, factoring in the stopway. In contrast, the take-off run available and the one engine failure case distances are primarily concerned with the distances required for a full takeoff with limited considerations for stopping. The all engine take-off distance is also focused solely on the performance aspects during the takeoff phase under normal operational conditions, without accounting for stopping distances in the context of a stopway. Thus, the unique aspect of the accelerate stop distance available is its inclusion of the stopway, enhancing safety margins during a critical phase of flight.
