A flight may be late departing or arriving from an airport because of the delays that occurred earlier on that day. From a small amount of initial delay, it can propagate and compromise on-time performance of the overall operations of the same aircraft. It can propagate on the next legs and compromise other flights as well which causes disruption in the network. A lot of research has been done in the area of flight delay propagation and many models were created to help airlines and operators reduce that very same effect. The Time Based Separation (TBS) project has brought new methods for separation of arrivals by time instead of distance. It’s a promising method for reducing flight delays. In this paper, by collecting flight records data from the Central Office for Delay Analysis in EUROCONTROL, we’ve observed a significant decrease in delays in case of strong headwinds, which proves the very point of TBS’s effectiveness in optimizing runway throughput and network operations. The dataset consisted of around 60’000 flights at London Heathrow airport. By using that data, a few analyses are executed which show us the overall effect on the network. |
