Aircraft Emergency Landing Site Selection: A Hierarchical Approach

In this paper we propose our approach to emergency landing site selection for an ultralight aircraft. We describe the emergency landing use case motivating our work and show related research. Thereafter we explain why we had chosen a hierarchical approach consisting of a simple high-level information based landing site preselection and emergency classification followed by a lower-level information based emergency runway ranking using Bayesian Networks. Furthermore, we explain the inputs used for the high- and low-level selection and the assumptions we make, as well as the structure of our Bayesian Networks. Finally, we discuss first results of our approach and give an overview of possible future improvements and future work.
