Abstract

A system and method for providing an aircraft turnaround schedule are disclosed. In one embodiment, a time taken for each aircraft turnaround activity is obtained from touchdown to takeoff of an aircraft from an aircraft on-board system by a ground station system. Further, the aircraft turnaround schedule is computed based on the obtained time taken for each aircraft turnaround activity using a dynamic buffer management approach by the ground station system.
