What Happens If an Airplane Loses Both Engines?

The thought of an airplane losing its engine or engines mid-flight is frightening. Many people imagine the plane dropping from the sky. However, modern airplanes are designed with safety features to handle such situations. Pilots receive extensive training to manage engine failures, ensuring passenger safety even in rare emergencies. This article explores what happens when an airplane loses one or both engines, focusing on aircraft design, emergency procedures, and real-life examples that show how reliable modern aviation is.

Redundancy in Aircraft Design

Modern airplanes do not rely only on their engines to stay in the air. The wings create lift as the plane moves forward, allowing it to glide even if the engines stop working. This is the same principle that keeps gliders in the air. A commercial plane can glide for a long distance if an engine fails, giving pilots time to troubleshoot, restart the engine, or find a safe landing spot. At a cruising altitude of 36,000 feet, an airliner can glide for about 60 to 100 miles.

Most commercial airplanes have at least two engines, which work independently. If one engine stops, the other one can still provide enough power to keep the plane flying and reach a nearby airport. To ensure that twin-engine planes can safely fly long distances over oceans or remote areas, aviation authorities have ETOPS (Extended-range Twin-engine Operational Performance Standards). These rules ensure that a twin-engine aircraft can safely reach an alternate airport with one engine.

Aircraft are also designed with multiple backup systems. For example, if one hydraulic system stops working, other independent systems take over to control the flight.

To prevent accidents from engine failures, aircraft have safety features such as:

• Fan blade containment rings: These rings keep engine parts from flying out if a fan blade breaks.
• System segregation: Critical systems like hydraulic lines and electrical wiring are placed in different areas to reduce the chance of both being damaged.
• Fuel tank dry bays: Empty sections in the fuel tanks help prevent fires if debris penetrates the tank.

Advanced in-flight entertainment systems also play a role in emergencies. They help pilots communicate with passengers, provide real-time updates, and keep passengers calm.

In the future, aircraft safety may improve even further with technologies like automatic fuel tank switching, more accurate fuel sensors, and advanced warning systems that detect engine problems before they happen.

Probability of Engine Failure

Engine failures do happen, but they are very rare. The FAA estimates that a jet engine fails once every 375,000 flight hours, meaning a failure occurs about once every 43 years of continuous flying. The chance of both engines failing at the same time is even lower.

Some common causes of engine failure include:

• Mechanical issues: Wear and tear or manufacturing defects can cause failures, though regular maintenance reduces this risk.
• Bird strikes: Birds flying into an engine can cause serious damage.
• Foreign object debris (FOD): Debris from runways or taxiways can be sucked into the engine and cause damage.
• Fuel issues: Contaminated fuel or improper fueling can lead to engine problems.
• Extreme weather: Severe storms, turbulence, or hail can damage engines or cause them to shut down temporarily.
• Maintenance errors: Poor maintenance practices can increase the risk of failure.

Sometimes, both engines can fail at once due to environmental factors. For example, a flock of birds could be sucked into both engines, or contaminated fuel could affect them both. This means that the risk of dual engine failure is not just the square of a single engine failure probability but depends on external conditions as well.

Procedures for Engine Failure

Pilots are trained extensively to handle engine failures. Simulators help them practice and prepare for real-life emergencies. The key steps in an engine failure scenario include:

1. Maintain Aircraft Control: Pilots focus on keeping the aircraft stable by managing speed, altitude, and direction.
2. Find a Safe Landing Spot: Pilots quickly identify the nearest airport or safe area to land.
3. Troubleshoot the Problem: If there is enough time and altitude, pilots try to restart the engine by checking fuel levels, switching fuel tanks, or adjusting settings.
4. Communicate with Air Traffic Control: Pilots declare an emergency and work with air traffic controllers to find the best solution.
5. Prepare for Landing: If an engine restart is not possible, pilots prepare the plane and passengers for landing, following emergency checklists.

Takeoff Procedures:

• Before V1 Speed: If an engine fails before reaching V1 (decision speed), the takeoff is aborted.
• After V1 Speed: If an engine fails after reaching V1, takeoff continues. The pilot uses the rudder to maintain control and climbs at V2 (safe takeoff speed).

Safety Regulations and Training Requirements

Aviation authorities enforce strict regulations to ensure pilots are prepared for emergencies. These include:

• Aircraft design standards: Planes must meet safety requirements to ensure they can operate safely even if one or more engines fail.
• Pilot training: Pilots undergo extensive simulator training to handle engine failures and emergency landings.
• Maintenance procedures: Airlines must follow strict maintenance schedules to keep engines in top condition.

For example, after a 2018 Boeing 737 engine failure, the National Transportation Safety Board (NTSB) suggested improvements in engine design to further enhance safety. Crew Resource Management (CRM) also plays a key role in emergencies, ensuring pilots work together effectively in high-stress situations.

Real-Life Examples of Safe Landings After Engine Failures

There are many cases where pilots successfully landed planes after losing one or both engines. Some famous examples include:

• Air Canada Flight 143 (1983): This Boeing 767 ran out of fuel due to a metric conversion error. The pilots glided the plane for 17 minutes and landed safely on an old airstrip in Gimli, Manitoba.
• United Airlines Flight 232 (1989): A DC-10 lost all hydraulic systems after an engine failure. The pilots managed to crash-land in Sioux City, Iowa, and many passengers survived.
• Air Transat Flight 236 (2001): An Airbus A330 lost both engines over the Atlantic due to a fuel leak. The pilots glided for 75 miles and landed safely in the Azores.
• TACA Flight 110 (1988): A Boeing 737 lost both engines during a thunderstorm but safely landed on a grassy levee in New Orleans.

These cases highlight the skills of pilots and the ability of modern aircraft to handle engine failures safely.

Final Thoughts

While engine failures may sound alarming, they are rare and well-prepared for in modern aviation. Airplanes are designed with backup systems, and pilots undergo rigorous training to handle emergencies. Continuous improvements in aircraft design, training, and safety regulations make air travel one of the safest modes of transportation.

As experts often say, “Pilots don’t rise to the occasion; they sink to their highest level of training.” This underscores the importance of preparation in aviation safety. While technology plays a vital role, the experience and skills of pilots ultimately ensure passenger safety.

By understanding aircraft design, emergency procedures, and historical cases, we can appreciate the resilience of modern aviation and the professionals who keep air travel safe.
