The Transport Aircraft Minimum Pollution Climb Schedule

Today ACARE ses the targets that drastically lower transport aircraft air pollution. Airline must find the strategy to satisfy a new pollution standard with the present aircraft performances and new flight techniques. The paper sets the analysis of airline direct operating cost increase in a climb flight phase, under the pollution reduction criterion. Presented analysis defines airline strategy, based on real aircraft performance and real environmental pollution constraints. In this investigation, obtained theoretical model of the optimal climb speed schedule with altitude is presented; under the criterion of minimum climb total cost and minimum climb pollution. Optimal climb speed schedule is controlled by CI. In this paper is proposed a new operative parameter PI for pollution minimization. The final result of paper is an operative climb schedule for PI and CI. This obtained climb schedule can be applied in any transport aircraft equipped with primary flight instruments: altimeter, air speed indicator and Mach meter, but also in modern turbofan transport aircrafts equipped with FMS.
