The objective of this thesis is to analyze the operational requirements of aircraft during the runway exiting maneuvers and the economic feasibility of high-speed runway exits. The motion of the aircraft is simulated by a computer program based on the appropriate equations of motion and steering inputs. The economic analysis of high-speed runway exits is based on a life cycle cost approach. Historical data of airline operating costs are also used in the cost estimations. The results show that high-speed runway exits are operationally feasible and economically profitable. The results are also presented graphically to show the effect of various steering commands on the vehicle turning maneuvering requirements and the effect of different economic parameters to the evaluation of high-speed exit utilizations. / Master of Science
