What is the purpose of a runway stopway?

The purpose of a runway stopway is to provide a safe area for an aircraft in the event that it needs to stop during takeoff or landing. This area is typically situated beyond the end of the runway and is designed to support an aircraft that may not have sufficient stopping power due to various factors such as a rejected takeoff or emergency landing. The stopway is usually constructed of materials that can adequately support the weight of the aircraft, ensuring that pilots have a safe buffer in case their landing or takeoff is not executed as planned. This feature enhances safety measures at airports, as it reduces the risks associated with runway overruns and provides an additional layer of protection for aircraft operating in various conditions.
