Is It Possible to Put a Parachute on the Outside of an Airliner to Prevent It from Crashing?

The idea of putting a parachute on the outside of an airliner to prevent it from crashing might seem appealing, but it raises numerous practical challenges. This article explores why such a concept is unlikely to be adopted, considering the size, weight, and operational requirements of commercial airplanes.

The Technical Challenges of Using Parachutes on Airliners

One of the primary reasons why parachutes cannot be used on airliners is due to their sheer size and weight. Airliners are massive, and a parachute large enough to slow down their descent would be exceedingly large and heavy. This would significantly impact the fuel efficiency and range of the aircraft. Additionally, the parachute would need to open quickly to be effective, but the high airspeed of airliners makes this difficult to achieve. This could lead to insufficient deceleration, potentially making a crash more likely.

Examples from Private Aircraft

Some small private aircraft do have emergency parachute systems, known as "parachute canopies" or "emergency parachute systems." One such example is the Cirrus Aircraft, which includes a parachute system for the pilot and front seat passenger. However, these systems are intended for specific emergency scenarios, not for the entire aircraft.

“The first time I got in a Cirrus, my instructor reached up to the overhead to arm the parachute mechanism by pulling a pin holding the lever in place. I said, 'Dick, you can put that pin back in. I am NOT popping that chute.’”

These systems are designed for single-piloted planes and provide an additional layer of safety in the event of a total loss of power or other critical failures. However, applying such systems to commercial airliners would be far more complex and impractical due to the scale and weight involved.

Weight and Cost Considerations

Adding a parachute system to an airliner would introduce unnecessary weight and cost. Commercial aircraft are already designed to be as light and efficient as possible. The material, deployment mechanism, and pilot training associated with such a system would add significant expenses. Moreover, the parachute would likely only be used in extremely rare and specific circumstances, making the investment impractical.

Aviation Design and Safety Considerations

Most airplane crashes are not due to complete loss of power or other catastrophic failures that a parachute could address. Instead, they often occur during non-runway landings or due to other issues. Modern airliners are designed with a range of safety features, including redundancy in power systems, automatic descent protections, and gliding capabilities. These features significantly reduce the likelihood and severity of a crash even without such an extreme measure as external parachutes.

In the case of a pilot deliberately deploying a parachute (such as in the previous anecdote), the aircraft would be badly damaged. Survivability is not guaranteed, especially with the added complication of handling a severely damaged aircraft.

Conclusion

While the idea of using a parachute to prevent airliner crashes is intriguing, it is impractical due to the scale of the aircraft, weight constraints, and operational challenges. Current aviation technology offers a range of safety measures that are better suited to ensuring the safety of passengers and crew. For now, relying on established safety protocols and rigorous pilot training remains the most effective approach.
