Which of the following statements regarding clearways is incorrect?

A clearway is an area beyond the runway that is designated for the safe deceleration of an aircraft in case of an engine failure during takeoff. The property of a clearway that makes the response correct is that there are no specific minimum width regulations imposed on this area, which aligns with the principles of aerodrome design and operational safety.

The width of a clearway can vary depending on the specific requirements of the aerodrome and is not rigidly defined, allowing aerodrome authorities some flexibility in its designation. This consideration is critical in ensuring operational safety while accommodating various types of aircraft operations.

In contrast, statements regarding a clearway involving its composition—such as being able to include land and water—or the prescribed gradient requirement illustrate the standard regulations surrounding clearways. Clearways must indeed maintain a gradient of 1.5% to ensure proper drainage and safety over the area. Furthermore, clearways are typically under the control and management of the aerodrome authority, which is crucial for operational oversight and compliance with safety regulations.
