A sustentabilidade é uma prioridade crescente na indústria da aviação, que busca continuamente maneiras de reduzir seu impacto ambiental enquanto melhora a eficiência operacional. Por este motivo e devido ao crescente aumento na procura, a aviação comercial enfrenta desafios constantes para melhorar a eficiência e reduzir custos. As etapas necessárias para garantir a chegada e realizar nova partida de um avião são crucias à economia e fluxo dos aeroportos, nomeadamente o desembarque e embarque. É fundamental que haja cada vez mais otimização de cada uma dessas etapas para proporcionar uma melhoria. O desembarque de um avião eficiente é decisivo para as companhias áreas, causando impacto direto na satisfação dos clientes e na lucratividade. Assim, o avião está disponível mais rapidamente para ser preparado para a realização
de uma nova rota. O principal objetivo desta dissertação passa por analisar diferentes estratégias de desembarque e identificar quais são as mais eficazes para reduzir o tempo total necessário para que todos os
passageiros abandonem a aeronave. Para alcançar o objetivo proposto, recorreu-se ao software Pathfinder no qual se desenvolveu um modelo de simulação de evacuação de um Airbus A320. No layout estudado, estavam disponíveis 156 lugares para passageiros, sendo 24 destinados à Business Class. Foram estudadas cinco diferentes estratégias, sendo que para cada uma delas foram testados dois cenários: a utilização de uma só porta e de duas portas. O estudo realizado, através de modelos de simulação, permitiu identificar que a utilização de duas portas em simultâneo é favorável à eficiência do desembarque. O desembarque completamente aleatório do Airbus A320 com 156 passageiros com a utilização de uma porta demora 380,1
segundos, enquanto a utilização de duas portas reduz esse tempo para 179,7 segundos. A aplicação de estratégias mais organizadas, demostram que o desembarque poderá ser realizado num menor tempo. A estratégia que melhor resultado apresenta é a estratégia 4, Center to Window in group, com um tempo necessário de 148,7 segundos com utilização de 2 portas, o que se traduz num ganho de 17% em relação ao desembarque aleatório.
Sustainability is a growing priority in the aviation industry, which is constantly seeking ways to reduce its environmental impact while improving operational efficiency. For this reason and with the increasing demand, commercial aviation faces constant challenges to improve efficiency and reduce costs. The steps required to ensure the arrival and departure of an aircraft are crucial to the economy and flow of airports, namely disembarking and boarding. It is essential that there is an increasing optimization of each of these steps to provide an improvement. The efficient disembarking of an aircraft is crucial for airlines, having a direct impact on customer satisfaction and profitability. Thus, the aircraft is available more quickly to be prepared for a new route. The main objective of this dissertation is to analyse different disembarking strategies and identify which are most effective in reducing the total time required for all passengers to leave the aircraft. To achieve the proposed objective, the Pathfinder software was used to develop a simulation model for the evacuation of an Airbus A320. The layout studied had 156 seats available for passengers, 24 of which were for Business Class. Five different strategies were studied, and two scenarios were tested for each of them: the use of a single door and two doors. The study carried out, using simulation models, identified that the use of two doors simultaneously is favourable to the efficiency of disembarkation. The completely random disembarkation of the Airbus A320 with 156 passengers using one door takes 380.1 seconds, while using two doors reduces this time to 179.7 seconds. The application of more organised strategies shows that disembarkation can be carried out in less time. The strategy that presented the best result is strategy 4, Center to Window in group, with a time required of 148.7 seconds using two doors, which translates into a gain of 17% compared to random disembarkation.
