ETOPS180

ETOPS180 is a certification standard for aircraft and their operations, which stands for Extended-range Twin-engine Operational Performance Standards with a 180-minute diversion time. This standard is set by aviation regulatory bodies such as the Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) to ensure the safety and reliability of twin-engine aircraft during long-range flights.

The "180" in ETOPS180 refers to the maximum time, in minutes, that a twin-engine aircraft is allowed to fly from a suitable diversion airport. This means that the aircraft must be capable of reaching an alternate airport within 180 minutes in the event of an engine failure. The certification process involves rigorous testing and evaluation of the aircraft's systems, engines, and overall performance to ensure they meet the required safety standards.

ETOPS180 certification is crucial for airlines operating twin-engine aircraft on long-haul routes, as it provides a higher level of safety and operational flexibility. It allows these aircraft to fly routes that were traditionally reserved for four-engine planes, offering more direct flight paths and potentially reducing fuel consumption and flight times. The certification process also includes regular audits and reviews to ensure ongoing compliance with the standards.

Aircraft and airlines must meet specific criteria, including maintenance programs, crew training, and operational procedures, to achieve and maintain ETOPS180 certification. This standard has become increasingly important as twin-engine aircraft have become more common and capable of flying longer distances.
