What is the length range for Runway Safety Areas?

Runway Safety Areas (RSAs) are designed to enhance the safety of aircraft operations during takeoff and landing. The correct option indicates that the length range for RSAs is between 240 feet and 1,000 feet from the runway centerline. This range is established in accordance with regulations set by aviation authorities, which aim to provide a clear space for aircraft to use in the event of an overrun or excursion.

Moreover, the specified width of 240 feet to 1,000 feet allows for varying types of runways and land use around airports, ensuring that there is adequate space to minimize hazards associated with aircraft operations. This range reflects industry standards to maintain safety levels across different airport configurations while also considering surrounding terrain and obstacles.

Other ranges provided in the options do not align with the established guidelines and standards set forth by aviation authorities for RSAs, thus affirming that the correct answer encapsulates the essential safety requirements for modern runway operations.
