What is the maximum length a clearway should not exceed?

• A. 1/2 TORA
• B. 1/2 TODA
• C. 100 m
• D. 1/2 ASDA

Answer: (A)

The correct understanding regarding the maximum length a clearway should not exceed is that it should be half of the Takeoff Run Available (TORA). The clearway is an area beyond the runway that is free of obstacles and is intended to provide additional safety for aircraft during takeoff. By stipulating that the maximum length of the clearway should not exceed half of the TORA, regulations ensure that adequate length is maintained for safe takeoff operations, accounting for various factors such as aircraft performance and potential emergencies. This guideline emphasizes safety by ensuring that the clearway, while offering additional space, does not compromise the length of the TORA that is necessary for the aircraft to reach its required takeoff speed and safely become airborne. The clarity in this regulation also aids in consistent design and operational practices across different airports, allowing for predictable performance in takeoff scenarios.
