How Long Can an Aircraft Fly After Losing an Engine?

Modern airliners are designed with an impressive level of redundancy to ensure the safety of passengers and crew. This redundancy extends to the aircraft’s engines, allowing them to continue flying even if one engine fails.

Redundancy in Aircraft Engines

Aircraft engines are critical components that provide thrust to propel the aircraft through the air. Modern airliners typically have two or more engines to provide backup in case of an engine failure. These engines are designed with independent systems, including fuel tanks and control systems, to minimize the impact of a single engine failure.

Flight Duration with One Engine

The duration of flight after losing an engine depends on various factors, including the aircraft model, the weight of the aircraft, and the atmospheric conditions. However, many modern airliners are designed to fly for extended periods with only one engine operational.

For example, the Boeing 777, a popular long-haul airliner, is certified to fly for up to five hours with only one engine operating. This is due to its advanced design, which includes three engines and a sophisticated flight control system.

Maintaining Flight

When an engine fails, the aircraft’s systems automatically reconfigure to maintain flight. The remaining engines increase their power output to compensate for the lost thrust. The aircraft’s flight control systems adjust to maintain stability and controllability.

During this phase, the pilots will typically communicate with air traffic control to declare an emergency and divert to the nearest suitable airport for landing.

Landing with One Engine

Landing an aircraft with one engine requires special procedures and training for pilots. The pilots must carefully manage the remaining engine’s power and use flight control techniques to maintain stability and control.

Modern airliners are equipped with aerodynamic features and systems designed to enhance their handling characteristics during one-engine operations. These features ensure that the aircraft can land safely even with reduced thrust.

Conclusion

The ability of modern airliners to fly for extended periods with one engine is a testament to the remarkable safety and engineering advancements in aviation. Redundant systems and advanced flight control technologies allow aircraft to maintain flight even in the event of an engine failure, ensuring the safety of passengers and crew.
