Can we build an aircraft that is nearly crash-proof and stall-free?
Many wonders if it’s possible to develop an aircraft that is entirely crash-proof and stall-free. Just like unsinkable ocean liners or uncrashable cars, the reality is that everything still carries some degree of risk.
However, it is entirely feasible to design and build an aircraft with an exceptionally high level of reliability and safety through meticulous engineering, rigorous testing, and stringent regulations.
When Airbus introduced the fly-by-wire A320 plane, it was initially hailed as nearly ‘uncrashable’ due to its alpha-floor protection system. This system automatically commands the plane to full power if it detects the aircraft is dangerously close to stalling.
Unlike a car, when an aircraft stalls, the engine doesn’t stop; it’s a result of disrupted airflow over the wing, leading to a loss of lift and potentially dropping off the skies unless corrective action is taken.
Despite the stall warning system and built-in redundancies, including backup systems, no safety measure can be considered entirely foolproof. An example of this is the Airbus A330 crash during a test flight on June 30, 1994, where human errors played a major part in it. In fact, approximately 80 percent of airplane accidents can be traced back to human errors.
One potential solution to mitigate human errors is the introduction of pilotless planes. However, a 2017 global survey revealed that most people would be hesitant to board a plane without a pilot, even if it meant cheaper airfare.
Another research focuses on developing large parachutes that can be attached to aircraft, allowing them to land safely in the event of total engine failures.
Notably, this concept has been relatively successful in small planes employing the Cirrus Airframe Parachute System. However, adapting such a system to larger and faster commercial airliners presents significant practical challenges.
Some experts suggest an alternative approach, where the aircraft is divided into smaller sections, each equipped with a mega parachute. These sections could be capsules located between the cockpit and the tail, housing passenger seating areas and having the ability to detach from the fuselage in an emergency.
Though viable solutions exist, their widespread implementation is hindered by the substantial costs associated with developing and constructing such advanced aircraft and parachute systems. Although these ideas may seem fanciful, they hold the potential to significantly enhance passenger and crew safety if perfected.
While creating a completely crash-proof and stall-free aircraft may remain an elusive dream, ongoing advancements in technology and safety measures do currently offer a very high level of aviation safety to the travelling public.
Have a safe flight everyone!
