Method to evaluate takeoff distance for nose-gear light aircrafts

The process of takeoff distance estimation for nose-gear light aircrafts involves several parameters such as aircraft total weight, runway type, engine power, aircraft geometry, aircraft aerodynamic characteristics, among others. This work demonstrates a method to evaluate the takeoff distance through monitoring the force system acting on the aircraft during the takeoff run. The numerical approach considers discrete time steps. Details of the implementation and limitations of the method are presented. Through this procedure it is possible to easily vary the basic aircraft configuration, allowing fast analysis of many different configurations to select the best for a particular performance.
