Aircraft approach operations

(2009 - ongoing)


Its not just the arrival sequence that matters

At busy airports, the landing capacity of a runway is often insufficient for the demand and, except at very quiet times, it is rare for approaching aircraft to be able to fly straight in to land. It is more common to apply intelligent re-sequencing to aircraft, perhaps slowing some down and speeding others up in order to attain a better landing sequence. At busier times aircraft may even need to circle in stacks awaiting their turn to land. At these times, it is vital to maintain a good landing rate at the runway. The landing sequence is important, but the physical constraints implied by the stacks and the flight paths cannot be ignored. This project, funded by EPSRC and NATS, through the Smith Institute for Industrial Mathematics and System Engineering, considers the real approach operations problems as well as the effects of the landing sequences upon the ground resources at the airport, intelligently linking the ground and air operations.
