A method suitable for dealing with extended longitudinal manoeuvres is outlined, based on a step-by-step integration process It is shown how the necessary calculation is carried out on a digital computer, using a programme consisting of two parts A general part is applicable to any manoeuvre, and a special part idealises the pilot's action in performing the particular manoeuvre under consideration Using two illustrative examples, it is demonstrated how the method can be used to deal with problems which usually come under the heading of performance, but nevertheless involve handling qualities Some numerical results aid in the illustration
