What does RESA stand for in aviation terminology?

RESA stands for Runway End Safety Area. It is a defined area at the end of a runway that is designed to enhance safety by providing a buffer zone for aircraft that may overrun the runway. The purpose of this area is to reduce the risk of injury to occupants and damage to the aircraft in the event of an overrun incident.

The RESA aims to improve the overall safety of airport operations, especially during landing and takeoff when the potential for runaway incidents is higher. It is part of international airport standards and is critical in maintaining compliance with safety regulations in aviation.

In the context of the other terms, while they may seem plausible, they do not accurately represent the established definition within aviation. The emphasis on "End" in the correct answer highlights the specific location of the safety area as it pertains to the runway's termination point, which is crucial for understanding its safety application in air operations.
