What does TODA equal?

• A. TORA + stopway
• B. TORA + clearway
• C. ASDA + clearway
• D. ASDA + stopway

Answer: (B)

The term TODA, which stands for Takeoff Distance Available, is critical in understanding the available takeoff performance parameters for an aircraft. Specifically, TODA is defined as the length of the takeoff run available plus any additional distance provided by a clearway. A clearway is an area beyond the takeoff runway that is kept clear of obstacles, offering an additional margin for the aircraft to gain altitude and speed, thus enhancing safety during the takeoff phase. The presence of a clearway helps to provide an extended takeoff distance, making it essential in considering the total distance available for takeoff. In contrast, other options such as stopway are designed to provide a safety margin in case of an aborted takeoff or a situation where the aircraft cannot become airborne. Although stopways can be vital in assessing the total available distance for safe operation, they do not factor into the TODA calculation, which strictly relates to the available distance for takeoff using the additional area of the clearway. Therefore, the correct definition of TODA is indeed TORA plus clearway.
