In this paper we introduce a new point mass model with reduced complexity. The adventage of this model is its usefulness for analytical investigations. The difference between this model and the usual one concerns mainly two points. The first is that we do not care about the angle of attack, which is the input parameter for the calculation of the lift via the lift coefficients. So these coefficients are not involved. Drag coefficients are involved. We use a quadratic drag law. The second point is that we do not use the bank angle but the bank angle rate as a control function. This has a remarkable consequence: at any time the state of aircraft is independent of the choise of the controls at this instant. This is not the case in the usual model: the bank angle determines the normal vector of the flight path. There are some more technical assumptions and simplifications to be described later.
