Aircraft approach operations

(2009 - ongoing)


It's 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 ... (more info)





Departure sequencing @ LHR

(2003 - 2007)


Helping runway controllers to get low delay schedules that reduce delays and pollution

London Heathrow is one of the busiest airports in the world and has more international passengers than any other airport. Scheduling arrivals and departures from the two runways are complex problems, but ones which are solved manually by runway controllers in the control towers ... (more info)





Integrating airport operations @ MAN/ZRH

(2009 - ongoing)


Towards holistic airport operations management to improve performance



This research (supported by EPSRC, and both Manchester and Zurich airports) involves students and researchers at four Universities in the UK: Nottingham, Lincoln, Loughborough and Liverpool. The main driver for this research is to decrease any detrimental effects of airport operations upon the environment. A number of airport operations problems are being considered ... (more info)





Optimising stand operations

(2009 - ongoing)


Increasing predictability to increase system performance

Modern airports are complex environments, where many different operations are performed in parallel. Many resource allocation problems occur at the stands and this project, funded by EPSRC and NATS, considers some of these ... (more info)





Robust airline scheduling

(2003 - 2009)


Obtaining fundamental insights in the robustness of airline schedules, underpinning the development of future scheduling models

The ASAP research group has worked in close collaboration with Air France-KLM to investigate new approaches to build more robust schedules. The approach implements minor changes in existing schedules that are unlikely to influence profitability but which help to improve robustness and reduce passenger delays ... (more info)





TSAT Generation

(2007 - ongoing)


Absorbing any excess necessary delay at the stands at busy times

Reducing delay at the runway is good for passengers, airlines and the environment, but the throughput of the runway is limited, so queues can accumulate at times no matter how good the scheduling is. To further reduce the environmental impact at the airport another ASAP project, again funded by NATS and EPSRC, considers the advantages of holding aircraft on the stands, before their engines are started, rather than at the runway ...
