Abstract

Vehicle impairment is one of the primary contributing factors that lead to Loss of Control. Preventing such events requires a comprehensive understanding of the aircraft behaviour under the impaired conditions. Performance and stability aspects of the impaired aircraft are normally addressed individually in previous studies. Constrained bifurcation analysis and continuation has been used in this paper, with the advantage that both performance and stability can be assessed simultaneously. Moreover, the results provide insight into the analysis of safe landing capability and the effectiveness of initiatives aimed at enhancing survivability. A modified numerical procedure is outlined and computational examples of a large transport aircraft under impaired condition are presented.
