What does the term "ETOPS" stand for?

The term "ETOPS" stands for Extended-range Twin-engine Operational Performance Standards. This designation is crucial in aviation as it refers to the criteria and regulations that allow twin-engine aircraft to fly routes that are more than 60 minutes away from an airport where they could safely land in the event of an engine failure. This standard was developed to provide safety and operational guidelines that aircraft must meet to ensure reliability during extended flights over oceans or remote areas.

Achieving ETOPS certification involves thorough analysis and compliance with specific performance metrics related to engine reliability, maintenance, and crew training, which ultimately enhances safety during long flights. Understanding ETOPS is vital for those involved in flight operations, as it informs planning and decision-making processes regarding route selection and aircraft dispatch.
