GUIDANCE TECHNIQUES FOR NEAR OPTIMAL LATERAL ESCAPE MANEUVERS IN THE PRESENCE OF WINDSHEAR

This study treats three 'missing' aspects of previous research on escape guidance strategies during microburst encounters. First, the performance of three longitudinal guidance laws in combination with one single lateral guidance law is evaluated when more than one microburst core is present. Altitude guidance proves to be the most robust and gives the most promising results, provided the reference altitude to which the aircraft is controlled, is selected properly. Second, attempts are made in this study to develop a logic that adjusts the reference altitude during the escape maneuver; these results are not always satisfactory. Third, the three degrees of freedom (DOF) model is extended to a full six DOF model in order to investigate the effects of inertia and windspeed variations over the aircraft's size on performance and controllability. Some recommendations for future research are presented.
