Adaptation of the LTO test to the local airports infrastructure

Abstract

The paper focuses on emission of harmful exhaust gas compounds from aircraft engines and draws on its impact on human health and life. Air transport, as the most dynamically developing branch of transport, has a very strong impact on the human environment. The paper discusses the methodology for assessing emission of harmful exhaust compounds from airports and mainly focuses on universal and widely used Landing and Take-off (LTO) test. The theoretical part of this paper also outlines global research activities which rely on modeling airport emissions. The research part includes the infrastructural analysis of the aerodrome movement area in Warsaw Chopin Airport, located in Polish capital city. The infrastructure analysis presented in the paper attends to estimate the actual taxiing time in chosen airport. The method used in the research relies on scenario modes which attribute to airplanes specific routes directly from the aircraft stand to the runway and after landing from the runway to the aircraft stand. Adopted scenarios describe the specific route of the aircraft, including used taxiways, curves and calculate its lengths. The infrastructural analysis leads to LTO testing in two options. The first LTO test is based on actual taxiing time, whereas the second one uses only standard certified taxiing time. The research highlights significant differences in the total emission which actually result from aircraft taxiing time.
