David Ziegler, who led the Aviation and Defense industry at Dassault Systèmes, announced his views and suggestions on the new norm.


According to Ziegler, airlines and airports that are back in operation can effectively simulate airflow and virus spread in the aircraft cabin. It can also redesign and test security procedures by working on a virtual model.

As the world strives to overcome the COVID-19 outbreak, the aviation industry will play a vital role in terms of economic recovery. There is a lot to do in this industry. The International Air Transport Association (IATA) predicts that the total number of passengers in 2020 will be 2019% lower than 48. According to an IATA survey, 40% of those who recently got on the plane say they will wait at least six months after the virus has been taken under control before getting back on board. It will be very important to gain the trust of these passengers. However, the industry already has a strong experience in preventing disease spread; therefore, airlines, airports and aircraft manufacturers already have strict security protocols.

Optimizing air quality

Airports, airlines and aircraft manufacturers pay attention to air quality not only to ensure the comfort of passengers, but also to prevent the spread of toxic substances and microbes. For example, air flow, pressure, temperature and quality are constantly monitored in AIRBUS aircraft cabinets and all of the air is renewed every three minutes. Thanks to high efficiency air particle filters (HEPA), air quality reaches standards in hospital operating rooms; so 99,99% of even particles as small as microscopic bacteria and viruses are removed.

To prevent the spread of the disease

Air transportation is one of the key points to prevent an emerging pandemic threat. For this reason, organizations such as IATA, the International Civil Aviation Organization and the World Health Organization are collaborating to develop regulations and best practices for industry workers to prevent the spread of the disease. For example, disinfecting aircraft cabinets is part of the routine cleaning scheme and disinfections are carried out in a row to minimize risks. Additional teams are working at the airports that provide cleaning of touch screens, handrails and other frequently used areas. Many airports also scan passengers to make sure people with fever or symptoms do not board the plane.

Measure models for safe activity

Digital airflow simulations; It can be used by airlines and airports in virtual probability scenarios to measure the effectiveness of measures such as social distance, wearing a mask or changing the flow of passengers to combat virus spread. These technologies have recently been used in air flow and virus propagation simulations, together with China's Middle-South Architectural Design Institute, to combat the spread of Covid-19 at Wuhan Hospital.

Airlines and airports that are operating again may take a similar approach to the safety of staff and passengers. Airlines can effectively simulate airflow and virus spread in the aircraft cabin, and can redesign and test security procedures by working on a virtual model. In addition, they can create high-quality videos that demonstrate how the procedures work, effectively communicate with all stakeholders and increase passenger confidence.

Airports can use the same technology to create simulation models to help them optimize the flow of passengers and test the effectiveness of safety measures and procedures. By testing their plans first in a virtual copy of the airport, they can optimize resources and minimize problems. They can also create videos that show employees and passengers that the environment is safe.

In the “new normal” following the pandemic, passenger safety must be established at every stage, from design to departure and flight. Thanks to the joint efforts of companies in the aviation ecosystem, such an end-to-end approach is already being implemented.
