Abstract

In an emergency situation with total loss of thrust the pilot is forced to perform an emergency landing under difficult conditions. The potential energy of the aircrafts altitude can be converted into kinetic energy to move a certain distance over ground. In the best case this enables the aircraft to reach a suitable landing field at a proper altitude and direction. In a previous paper we presented a fast and non-iterativ algorithm to calculate glide pathes to a moving target in the wind frame. In this paper we discuss the necessity of precise wind prediction and extend the algorithm to be robust towards misestimation of wind force or wind direction. Furthermore, we consider a selection strategy in case that more than one valid glide path is feasible. Here, the strategy selects the trajectory that offers an alternative path as least as possible and is also robust against of the wind misestimation.
