Survival in the Skies: A Hypothetical Scenario of Complete Engine Failure on an Airbus A380

Imagine this: an Airbus A380, the largest commercial jetliner in service, is just 150 feet above the runway. Suddenly, all four engines have lost their thrust. The crew pulls off a remarkably survival-focused maneuver, drawing on their training and the lessons learned from real-life incidents such as Scandinavian Airlines Flight 751, where all two engines failed after takeoff despite the extreme improbability of such an occurrence.

The Unlikely Reality and Consequences

While it's almost impossible to lose all four engines on a modern jet, scenarios like these can teach valuable lessons. Let's dive into what happens if this were to occur in a worst-case scenario, including a detailed timeline of actions a pilot might take.

Understanding the Immediate Situation

The airplane is at a critical stage: at 150 feet above the ground, with a full gross takeoff weight and a passenger load along with cargo. The runway is likely already far too short to make a successful landing, given the speed the plane has already reached. The pilots are faced with a split-second decision to either attempt a dangerous emergency landing, or hope for the best and hope that there is suitable ground to come to a stop.

Pilot's Actions in the Event of Complete Engine Failure

Assuming the pilot is in command of an Airbus A380, here's what their initial steps might look like:

Timeline of Actions

0:00:00 - Apply takeoff power after cleared for takeoff 0:00:55 - Reach 100 knots (airspeed alive) 0:01:12 - Reach V1 - speed no longer to be aborted takeoff 0:01:25 - Reach V2 - safety speed 0:01:30 - Gear up command 0:01:32 - Reach 75 feet AGL (above ground level) 0:01:39 - Gear up 0:01:40 - Clear of runway 0:01:44 - Reach 150 feet AGL 0:01:45 - Engines go offline, climb stops

The plane has been airborne for about 20 seconds at this point. The pilot's priority is to fly the airplane, even if it means taking a nose-down attitude to avoid stalling the wings. Obstacles must be cleared and turns should be avoided unless absolutely necessary, as they will increase stall speed.

Preparing for Emergency Landing

The flight crew follows the plan, briefing on any critical obstacles that must be cleared during takeoff, and deciding on the landing area. The plane is positioned within 15 degrees of the centerline of its present heading, with around 24 seconds until impact, depending on the speed and altitude.

Key Actions

0:01:49 - Lower the nose to avoid stalling the wings 0:01:51 - First Officer (F/O) calls Mayday to the tower 0:01:52 - Reach 130 feet AGL 0:01:55 - Prepare for crash landing 0:01:57 - Reach 100 feet AGL 0:01:59 - F/O announces emergency to passengers and crew 0:02:00 - Reach 90 feet AGL

As the descent begins, the pilots will try to land the plane as safely as possible, facing the numerous challenges of a controlled emergency landing. Despite the extremes of this scenario, the cooperation and preparedness of the flight crew are critical to the survival of all aboard.

Lessons Learned

While the occurrence of such a scenario in real-life is exceedingly rare, the training and protocols derived from incidents like the Scandinavian Airlines Flight 751 and the British Airways Flight 09 illustrate the importance of thorough preparation and firm discipline in the face of extreme circumstances. Pilots and crew must be ready to handle unexpected situations with the trained instinct necessary to ensure passenger safety.

Conclusion

The Airbus A380 and similar large aircraft are designed with a multitude of safety features and protocols to minimize the risk of such scenarios, but the rare occurrence highlights the critical importance of thorough training and readiness. Pilots and crew must be prepared for the worst, and the lessons learned from such rare events can save lives.
