Commercial jets can fly for hours on a single engine
Modern aviation safety relies on a strict set of rules called ETOPS, which ensures that twin-engine planes are never more than three hours from a safe landing strip.
When a massive Airbus A310 cruises over the ocean, it carries a hidden insurance policy known as ETOPS. This protocol is the reason a pilot can lose an entire engine and still keep the aircraft aloft for up to 180 minutes. Instead of spiraling toward the water, the plane essentially becomes a highly efficient glider with a single power source, maintaining enough thrust to reach a pre-selected alternate airport like Ankara's Esenboğa in Turkey. These designated runways must be at least 2,800 meters long to ensure the heavy jet can stop safely even with reduced braking power.
