Why small planes are rarely seen flying over the open ocean
In short: Flying over the ocean presents unique logistical risks. This video explains the ETOPS certification system that dictates which aircraft are permitted to fly long-haul routes over water and the specific safety requirements they must meet.
ETOPS, or Extended-range Twin-engine Operational Performance Standards, is the regulatory framework governing twin-engine aircraft on long-haul routes. Because a single engine failure over the ocean poses a critical risk, aircraft must be proven capable of flying a specific distance on one engine to reach an emergency landing site.
The certification depends on engine reliability, navigation precision, and the proximity of diversion airports. These regulations determine which aircraft, like large twin-engine jets, can fly transoceanic routes versus smaller planes that must stay closer to land.
