A means to reduce noise during approach is to increase the glideslope angle. The steeper the glidepath, the worse aircraft can reduce their speed to landing speed. Pilots configure the aircraft earlier or even use spoilers with deteriorating effects on noise. The aim of this work is to analyse the most influencing factors on the ability of aircraft to fly steeper approaches.
