The article will explore and collect information about the possible accidents with the Airbus 220-300 aircraft, which is the new and largest aircraft that can be serviced at Riga airport. Previously, such a large plane had not been serviced at Riga Airport, so the article will gather technical information about the characteristics of the Airbus 220-300 compared to previous model planes. As part of the work, passenger evacuation modelling will be carried out with the help of the Pathfinder program, which will be used for emergency simulation. The results of the study may be used to implement further improvements, as well as to ensure more efficient firefighting team work in emergencies in the Riga Airport liability area, as well as other airports serving the Airbus 220-300 aircraft. Reaching the aim will provide an opportunity to look at different variations in the evacuation of people depending on the composition of passengers, behaviour and location of escape exits.
