This paper describes a method to investigate the benefits of a new high-lift system with continuously moving slats and flaps. The approach is evaluated, where a typical airliner decelerates during descent. The slat/flap setting is configured stepwise after the maximum allowable speed of the next slat/flap configuration is reached. Thus, most of the time the aircraft does not fly in its aerodynamic optimal configuration. The new system automatically adapts the slat/flap setting based on the airspeed and aircraft mass and enables the aircraft to fly with the aerodynamic optimal configuration. The performance is analysed using a flight simulation of a typical mid-range airliner and under variation of the conditions for a standard approach procedure. The assessment tool CoFA (Continuous Flap Assessment), developed in the project Con.Move, is capable of analysing performance benefits of continuous slat/flap settings. This paper describes and demonstrates the method by showing the influences of continuously moving slats and flaps on flight path, duration of the approach and fuel consumption for five different control laws for the extension of the slats/flaps using the tool CoFA. It gives an overview of the simulation environment and the developed functions of the tool, describes the approach procedure, and shows the resulting flight path for the different control laws.
