The Evolution of ETOPS Enabling Long-Haul Flights for Twin-Engine Jets - Regulatory Milestones - The Origins of ETOPS
The origins of ETOPS (Extended-range Twin-engine Operational Performance Standards) date back to the 1980s when the US Federal Aviation Administration (FAA) allowed Trans World Airlines (TWA) to fly their Boeing 767 aircraft from Boston to Paris.
This marked the beginning of ETOPS, which enabled twin-engine jets to fly long-haul flights.
Over the years, the FAA has increased the ETOPS rating, allowing for more flexibility in flight routes.
The development of ETOPS has been crucial in transforming twin-engine planes into efficient long-haul machines.
Today, ETOPS has become an essential aspect of commercial aviation, enabling twin-engine jets to fly long-haul flights over water or remote areas.
