An area symmetrical about the extended runway centreline and adjacent to the end of the strip primarily intended to reduce the risk of damage to an aeroplane undershooting or overrunning the runway is the definition for:

• A. clearway
• B. stopway
• C. runway end safety area
• D. none of the above

Answer: (C)

The concept here is the buffer zone at the end of a runway designed to reduce damage if an aircraft undershoots or overruns. This area is the runway end safety area, placed beyond the end of the runway and symmetric about the extended centreline to provide a protective, obstacle‑free space right at the runway’s end. It acts as a safety cushion, helping to dissipate energy and reduce the severity of an overruns or undershoots.

A stopway is a paved area beyond the runway used to support an aircraft during an aborted takeoff, not primarily for landing safety. A clearway is an area beyond the runway kept clear for potential maximum takeoff distance, but it’s for climb performance during takeoff rather than protecting the landing end.
