The most dangerous stage of air travel – the aircraft taxiing

January 30, 2024
Statistical data shows that air travel is the safest means of transportation. According to the International Air Transport Association (IATA), in 2022, 32.2 million flights were operated, and out of this large number, only 39 flights ended in accidents. Most aircraft accidents occur during take-off and landing, where the aircraft is the closest to the ground.

According to statistical research by Boeing, 16% of fatal accidents occur during the take-off and initial climb, while 29% occur during the phase of landing. During these moments, the aircraft's speed and altitude are at their lowest, more manoeuvres are performed, and there are more other aircrafts in the space.

Incident at the Japanese airport

This month in Tokyo, a Japanese Airlines aircraft collided with a Japanese Coast Guard plane while taxiing. The passenger plane skidded, and members of the coastal guard service in the other aircraft, which was flying to assist those affected by an earthquake, lost their lives.

According to Vincas Snirpunas, an expert in aviation and lecturer at Vilnius Gediminas Technical University's Antanas Gustaitis' Aviation Institute (AGAI), it is still difficult to talk about the exact cause of the accident, but it could be presumed what may have influenced this accident.

"Aircraft collided due to poor coordination of the taxiing-takeoff route. Taxiing is the most dangerous stage, requiring maximum vigilance from the crew, flight commanders, and ground services," says the aviation expert. "First of all, we must thank and commend the crew of the Japanese airline, who managed to control the passengers and save all 376 lives. When an aircraft experiences an accident – colliding with another aircraft on the taxiing route – the crew did not panic and correctly, following the instructions, executed the passenger evacuation."

According to the aviation expert, the most complex and dangerous stage of the flight is the aircraft taxiing, requiring maximum vigilance from the crew, flight commanders, and ground services. Of course, the technical condition of the aircraft must also be suitable for safe taxiing.

The accident raises important questions

According to Vincas Snirpunas, an expert at VILNIUS TECH, aviation companies currently use procedures and methods that help evaluate the risk of each airline's flight:

"All organizations involved in aviation that are directly involved with flights have implemented Safety Management Systems (SMS), which allow identifying or modelling situations very close to an incident or accident. If such situations are identified, the organization must take preventive action to reduce flight risk, thereby reducing the likelihood of an accident to zero."

However, the incident in Japan, according to V. Snirpunas, raises many questions: "Why didn't the aircraft stop but rolled onto the takeoff-landing route? Why didn't the border guard aircraft hear that the other aircraft was descending into the same route? Why didn't the taxiing aircraft notice that the other aircraft was on the route? Why didn't the flight commanders notice that two aircraft were on the same route at the same time? All these questions, I believe, will be answered by a detailed investigation of the accident."

Although statistically air travel remains the safest way to travel, aircraft accidents often cause great fears. In the event of an accident, it is important to check safety systems and communication between airport units not only in the affected country but also for airports worldwide.

Based on probabilities, IATA calculated that a person would have to fly once a day for 25,214 years to experience at least one life-threatening incident.

From car enthusiast to well-paid engineer: Dominykas turned his passion into a career
From car enthusiast to well-paid engineer: Dominykas turned his passion into a career
A lifelong fascination with cars, a desire to understand how complex systems work, and a curiosity to find better engineering solutions led Dominykas Eičinas to study Automotive Engineering at VILNIUS TECH. After completing both his bachelor's and master's degrees, he now works as a vehicle engineer and enjoys the fact that his passion has become a well-paid profession. Asked why he chose to study Automotive Engineering after graduating from school, Dominykas says the decision was inspired by his childhood interest in technology. [caption id="attachment_122203" align="alignnone" width="2560"] Dominykas Eičinas[/caption] "My father competes in karting races, so from an early age I was fascinated by cars. I built them out of LEGO, constantly taking things apart and putting them back together. I still remember that when I was about ten years old, I built an independent car suspension from LEGO pieces. It was surprisingly realistic, complete with driveshafts and a differential. Looking back, I think that was probably the moment my engineering mindset began to develop," recalls the VILNIUS TECH alumnus. Dominykas admits that not every STEM subject came easily to him at school. Physics was not his strongest subject, and mathematics also required considerable effort. However, that did not prevent him from successfully enrolling in the Automotive Engineering programme. "The most important thing is the willingness to learn and to work consistently. Results come with dedication and effort," he says. The best part: seeing ideas become reality During his studies, the most memorable experience for Dominykas was the practical coursework and designing with SolidWorks. Although he had first encountered the software at school, it was only at university that he truly discovered its full potential. "At first, it seemed incredibly complicated, but our lecturers explained how to use it during classes. That's when I realised it was a creative tool—you can design almost anything you can imagine. What impressed me even more was the moment when a vehicle model (or any other design) created on a computer became a real product," he says. [caption id="attachment_122207" align="alignnone" width="2560"] Faculty of Transport Engineering[/caption] He also enjoyed laboratory work, where students could observe changes in vehicle parameters, perform measurements, and analyse real engineering data. A Master's degree as a competitive advantage After completing his bachelor's degree, Dominykas decided to continue with a master's programme. His decision was driven not only by a desire to deepen his professional knowledge but also by the goal of becoming more competitive in the labour market. He began actively looking for a job a few months before graduation and received an offer quite quickly. Today, he works as a vehicle engineer at a company specialising in van conversions and the design of customised vehicles. Together with his colleagues, he develops a wide range of minibuses—from school and intercity transport to premium business-class vehicles. "Every project is different. Clients' needs are constantly changing, so no two working days are ever the same. We are always looking for new solutions, discussing ideas as a team, and creating custom projects," he explains. Demand for engineers continues to grow According to Dominykas, Automotive Engineering graduates have little difficulty finding employment, and even those without previous work experience can expect a competitive salary. [caption id="attachment_122205" align="alignnone" width="2560"] Faculty of Transport Engineering[/caption] "I believe the demand for transport engineers will only continue to grow. This profession opens up many career opportunities, and the knowledge you gain allows you to work not only in the transport sector but across many areas of engineering. Automotive Engineering graduates are sought after in vehicle design, manufacturing, component development, product engineering, and many other engineering companies. And if you manage to turn your hobby into your profession, as I did, every working day becomes enjoyable," he says. A passion for virtual motorsport Even after work, Dominykas never strays far from cars. For many years, he has been passionate about virtual motorsport. "My father races karts, so cars have always been an important part of our family. I even have a photo of myself at around four years old, gripping the steering wheel of a racing simulator in front of a computer screen, already 'racing'. Real-life motorsport requires a huge financial investment, while virtual racing allows me to experience much of the same excitement at a fraction of the cost," he says. While studying at VILNIUS TECH, he and several like-minded students founded the university's virtual racing team, Automotive Engineers by VILNIUS TECH University. "The team was established in 2022 and competes in various virtual motorsport championships. Since then, we've reached the podium several times and have even won a number of races. It's great to see that the project is still going strong and that new students continue to join the team," he says. Dreaming of the world's leading automotive brands Even while finishing school, Dominykas dreamed of working for one of Germany's major automotive manufacturers. That ambition was one of the reasons he chose to study in English at VILNIUS TECH. Although working for companies such as Volkswagen, BMW, or Porsche remains a future goal, he has not given up on that dream. "For now, I'm very happy in Lithuania. Life sometimes has a way of leading you down the right path. We'll see what the future brings," he says.
