When a stopway and/or clearway is available, what should the TOD not exceed when multiplied by a factor of 1.15?

The take-off distance available (TODA) is the total distance available for the aircraft to take off, which includes the runway length plus any stopway and/or clearway. In specific operations where a stopway or clearway is available, the TODA can be particularly relevant for determining operational limits. When the question refers to the take-off distance not exceeding the take-off run available (TORA) multiplied by a factor of 1.15, it implies that the aircraft's take-off run—represented by TODA—must be calculated with the understanding that additional distance from a stopway or clearway is beneficial. The utilization of that factor accounts for safety margins and variables in performance calculations. Using the value of TORA as a baseline, the multiplication by 1.15 means that the full potential of the take-off distance—including the extra safety provided by the stopway and clearway—can accommodate increased performance demands without endangering operational safety. Thus, it reinforces the principle that available distances during take-off have to include all relevant components of runway extension to maintain regulatory compliance and safety norms.
