Um estudo comparativo dos aeroportos de Natal (NAT/SBSG) e São Paulo (GRU/SBGR) como hub internacional EUR-SAM : análise de custo e eficiência de capital aplicado em frota

Abstract

Given the strategic geographical location of the city of Natal / RN for aviation, this work paper presents a comparative analysis of fleet capital expenditure and efficiency between the Governador Aluízio Alves International Airport (NAT/SBSG) and the Guarulhos International Airport (GRU/SBGR), in the context of an EUR-SAM hub (Europe - South America). The study is based on the comparison between NAT/SBSG and Guarulhos International Airport, which is currently the international hub of Brazil. For this study, the cycle times of aircraft departing or landing at these Brazilian airports were analyzed for ten European destinations - Lisbon, Madrid, Barcelona, London, Paris, Amsterdam, Frankfurt, Zurich, Milan and Rome. The cycle is completed each time the aircraft returns to its original airport. This analysis was performed because cycle times over 24 hours mean that for a daily flight demand for each of these destinations, it would take more than one aircraft, which can significantly increase fleet capital costs. In addition to the cycle time, the optimum range of the aircraft used in these flights was also analyzed, since flights operated in distances within the optimum range can carry their maximum load and thus increase the efficiency of the capital applied in fleet. For both analyses, NAT/SBSG is more advantageous, since 100% of its cycle times are less than 24 hours, while for GRU/SBGR, only 20% are. In addition, 75% of flights analyzed from or to GRU/SBGR are out of the optimum range of the aircraft, while 50% of NAT/SBSG origin or destination flights are flying out of the aircraft's optimum range.
