Air transportation networks play important roles in human mobility. In this paper, from the perspective of multilayer network mechanism, the dynamics of the Chinese air transportation network are extensively investigated. A multilayer-based passengers re-scheduling model is introduced, and a multilayer cooperation (MC) approach is proposed to improve the efficiency of network traffic under random failures. We use two metrics: the success rate and the extra transfer number, to evaluate the efficiency of re-scheduling. It is found that a higher success rate of passengers re-scheduling can be obtained by MC, and MC is stronger for resisting the instability of the capacity of links. Furthermore, the explosion of the number of extra transfer can be well restrained by MC. Our work will highlight a better understanding of the dynamics and robustness of the Chinese air transportation network.

Resumo: A crise sanitária ocasionada pela Covid-19 tem demonstrado que o novo coronavírus não acomete apenas as vias mais distantes do pulmão humano, mas também os fluxos da economia mundializada. Neste artigo analisamos as consequências do novo coronavírus na rede de transporte aéreo no primeiro semestre de 2020 a partir de uma abordagem multiescalar. Os procedimentos metodológicos basearam-se em coleta de dados do fluxo de transporte aéreo e de informações referentes a casos de Covid-19 em localidades selecionadas. As principais bases de dados utilizadas foram a Agência Nacional de Aviação Civil (ANAC), a International Civil Aviation Organization (ICAO), a Organização Mundial da Saúde (OMS) e relatórios de concessionárias de aeroportos. A análise leva a refletir sobre a dependência das corporações, especialmente de grandes companhias aéreas, às ações do Estado e revela um sistema de espoliação (e de pilhagem) ainda mais agressivo e articulado em tempos de crise como essa ocasionada e/ou agravada pela Covid-19. Palavras-chave: Covid-19. Transporte aéreo. Fluidez. Crise econômica. Through the flows and the scales: Covid-19 and its implications for the air transportation network in the 1st semester of 2020Abstract: The health crisis caused by Covid-19 has shown that the new coronavirus affects not only the most distant pathways of the human lung but also the flows of the globalized economy. In this paper, we analyze the consequences of the new coronavirus on the air transportation network in the 1st semester of 2020 in a multiscale approach. The methodological procedures were based on the gathering of air transportation flow data and information related to Covid-19 cases in selected locations. The main databases were the National Civil Aviation Agency (ANAC), the International Civil Aviation Organization (ICAO), the World Health Organization (WHO), and reports from highway and airport concessionaires. The analysis leads to reflect on the dependence of corporations, especially large airlines, on the actions of the State and reveals a system of exploitation (and looting) even more aggressive and articulated in times of crisis such as that caused and/or aggravated by COVID -19.Keywords: Covid-19.

Entre flujos y escalas: Covid-19 y sus implicaciones en la red de transporte aéreo en el primer semestre de 2020Resumen: La crisis sanitaria derivada de la Covid-19 ha demostrado que el nuevo coronavirus no solo afecta a las vías más distantes del pulmón humano, sino también a los flujos de la economía globalizada. En este artículo analizamos las consecuencias del nuevo coronavirus en la red de transporte aéreo en el primer semestre de 2020 desde un enfoque multiescalar. Los procedimientos metodológicos se basaron en la recopilación de datos de flujo de transporte aéreo y de información relacionada con los casos de Covid-19 en ubicaciones seleccionadas. Las principales bases de datos utilizadas fueron la Agencia Nacional de Aviación Civil de Brasil (ANAC), la International Civil Aviation Organization (ICAO), la Organización Mundial de la Salud (OMS) y los informes de las concesionarias de aeropuertos. El análisis lleva a reflexionar sobre la dependencia de las corporaciones, especialmente las grandes aerolíneas, a las acciones del Estado y revela un sistema de saqueo aún más agresivo y articulado en tiempos de crisis como esta provocada y/o agravada por el nuevo coronavirus.Palabras clave: Covid-19. Transporte aéreo. Fluidez. Crisis económica.
