ETOPS, an acronym for Extended-range Twin-engine Operational Performance Standards, refers to a set of regulations established by the International Civil Aviation Organization (ICAO) to ensure the safe and efficient operation of twin-engine aircraft on long-distance flights over remote areas, including oceans or deserts.
ETOPS certification is obtained by aircraft manufacturers for their twin-engine planes, indicating the aircraft's capability to reliably operate for extended periods of time on one engine in case of an engine failure. This certification depends on various factors, such as the aircraft's design, performance, maintenance, and crew training.
The ETOPS standards dictate the maximum time and distance an aircraft can be from an alternate airport on the planned route of flight. Typically, ETOPS certifications range from ETOPS-120 to ETOPS-330, indicating the allowed period of maximum diversion time in minutes, which can last from 120 minutes to 330 minutes.
ETOPS has significantly impacted the airline industry, allowing twin-engine aircraft to fly more efficient and direct routes across long distances, reducing fuel consumption and costs. This certification opened up new routes for airlines, providing increased connectivity between distant locations. This, in turn, has enhanced the development of long-haul operations with twin-engine aircraft, making it a vital component of global aviation.
