Abstract:
For the VTOL aircraft mission profiles, terminal phases are considered the most crucial and convoluted due to the interrelated aspects involved in transition from level flight into vertical motion. Flight safety is the trivial, yet essential requisite that should be satisfied during all flight phases. This paper aims to present a comprehensive model for determining a safe distance for urban VTOL air taxies during the landing phase through predicting possible conflictions and reducing this possibility by performing a conflict resolution maneuver while maintaining the flight safety requirements.The safe distance during landing is calculated based on a Monte-Carlo simulation which employs the dynamic model of the aircraft. This simulation also provides us with the conflict resolution maneuver. This maneuver is designed using a non-cooperative approach and is able to solve the problem in a 3D environment. Finally, the calculated distance and proposed maneuver are reported as the results of this simulation and output of our model
