Summary

The climb performance of a turbo-jet transport aircraft is considered, using the concept of the energy height. The analytical formulae used in evaluating the time needed, distance covered and fuel consumed during climb under various conditions are developed. It is concluded that the application of this energy approach method to the climb performance estimation of a turbojet transport aircraft will prove satisfactory from the points of view both of the accuracy of the results and of saving some of the considerable time needed for the climb calculation by the conventional method. A numerical example is given to illustrate the usefulness, applicability and flexibility of this method.
