When calculating TODA, what is the maximum limit in relation to TORA?

The maximum limit of TODA (Takeoff Distance Available) in relation to TORA (Takeoff Run Available) is indeed set at 1.5 times the length of TORA. This means that the total distance available for takeoff, which includes the takeoff run and the distance available to continue the climb after takeoff (in the event of an engine failure or similar scenario), cannot exceed 1.5 times the takeoff run available.

This regulation ensures a safe margin for aircraft performance during the critical phases of takeoff, helping to account for potential obstacles and ensuring that there is sufficient runway length available should an aircraft need to abort takeoff and come to a stop safely. Understanding this limit is crucial for pilots and flight planners to ensure compliance with safety standards and operational procedures.

The other options suggest different relationships that either do not reflect regulatory practices or imply that safety considerations are not being sufficiently prioritized, which could lead to unsafe operational scenarios.
