Résumé / Abstract

Aircraft noise and air pollution are considered to be one of the most significant environmental concerns on the local community of modern cities, affecting people living in particular near airports. Previous researches suggested that people living around airports are a high risk group, vulnerable to the effects of aircraft operations. This is supported by evidence that aircraft noise and pollution exposure have also been associated with reduced psychological well-being, lower self-reported quality of life and higher levels of self-reported stress. Aircraft noise and pollution exposure seem to be associated with anxiety, depression and psychological morbidity. The objective of this contribution is to implement an optimization model generating optimal flight paths minimizing noise levels, fuel consumption and air pollution during aircraft operations. It is obviously fitting with technological developments in progress on aircraft engines and fuselages. Operational and safety constraints have been considered and their limits satisfied. Features of applied numerical methods using AMPL programming language and KNITRO solver, have been carried out and tested. We have solved a nonlinear and a non convex optimal control problem governed by an ordinary differential equations system (ODE). A continuous descent has been found as an optimized flight path reducing noise, fuel consumption, and therefore the pollutant emissions. Keys-words: air pollution, noise abatement, aircraft, constraints, procedures, optimal control, flight paths.
