When we think about a mistake in the case of retail, entertainment or any other industry that affects us every day, we realize that its effects are acceptable and reversible. Did you ever get the wrong e-commerce order? What are the worst consequences of such a situation? Let’s be honest, you will just order this product from another supplier. Maybe you won’t be content with this unpleasant situation but for sure it’s something you can fix and still continue with your daily activities. 

Now think about the airline industry. What if there is a miscalculation in the flight control system? Error in the operation of the engine control system? Or perhaps improper operation of the emergency system, which is designed to respond to crisis situations? As you can guess, the consequences can be much more serious. 

That’s why one of the main characteristics of aviation software is reliability.

Why is reliability so important in aviation software?

Aviation and aerospace are industries where safety is non-negotiable. Any glitch or failure in the software can have catastrophic consequences. Navigation, communication, engine control, automation – every aspect of flight is intricately tied to software. Reliability ensures that these systems function as intended, minimizing the risk of accidents and guaranteeing the safety of passengers and crew.

Modern aircraft rely on intricate software algorithms to navigate through complex airspace, optimize routes and execute precision landings. The reliability of these systems is crucial, as any glitch or error could have severe consequences. Reliable software ensures that aircraft can follow planned routes accurately, respond promptly to air traffic control instructions and navigate through adverse weather conditions, contributing significantly to the overall safety of air travel.

Preventative maintenance, as another example, is a key to ensuring the continued airworthiness of aircraft. Software-driven maintenance and diagnostic systems play a pivotal role in monitoring the health of aircraft components, predicting potential issues and scheduling timely maintenance activities. The reliability of these software systems is paramount to avoid unexpected failures and minimize downtime. 

The aviation and aerospace industries are also always at the forefront of technological innovation. New challenges, advancements and requirements constantly emerge. Reliable software is designed with adaptability in mind, allowing for seamless integration of updates, patches and new functionalities. This ensures that aircraft and spacecraft can evolve with the industry.

What if the aviation software fails?

The devastating crash of a Lion Air Boeing 737 Max 8 in the Java Sea in 2018 highlighted the alarming reality that even seemingly minor software code defects can lead to catastrophic consequences. The incident, resulting in the tragic loss of all 189 passengers and crew, was attributed to a glitch in the aircraft’s flight-control software, underscoring the profound impact of software reliability on aviation safety.

Following the crash, investigators identified a crucial issue with the plane’s sensor readings, essential for the proper functioning of the flight-control system. The Federal Aviation Administration (FAA) swiftly issued an emergency notice to operators of Boeing 737 Max 8 and 9 planes, acknowledging that inaccurate sensor data could pose a significant risk of losing control and potentially result in a catastrophic crash. 

This incident once again emphasizes the crucial notion that software plays a fundamental role in safeguarding the lives and safety of individuals, particularly in air travel. The aviation industry, with its intricate systems and dependence on software, serves as a poignant reminder that technological advancement must be coupled with rigorous testing, oversight and continuous improvement to uphold the highest standards of safety and reliability.

Securing the aviation ecosystem

The significance of software in ensuring the safety, efficiency and overall success of air travel can’t be overstated. Among the various attributes that define the effectiveness of aviation software, reliability emerges as the linchpin. From navigation and flight control to maintenance, communication and passenger management, reliable software is the fundament of a robust and secure aviation ecosystem. As the industry continues to evolve, maintaining and enhancing the reliability of aviation software is a top priority to safeguard air travel.

Reflecting on your last air travel experience, did you ever wonder how reliable aviation software contributed to the ease of your journey?
