What type of speed is refusal distance associated with during a rejected takeoff?

Refusal distance is closely linked to stopping distance requirements during a rejected takeoff. This distance is critical as it represents the minimum distance required for the aircraft to safely stop on the runway after the decision to abort the takeoff has been made. It takes into account multiple factors, including aircraft weight, runway conditions, and braking performance.

Understanding refusal distance is vital for pilots because it directly influences their decision-making during takeoff. If a pilot determines that they are unable to stop safely within the available runway length due to exceeding the refusal distance, they will know that continuing the takeoff is not a safe option. This highlights the importance of assessing runway length and conditions before initiating a takeoff to ensure that the aircraft can safely stop should a rejection be necessary.
