Research On The Design Of End-Around Taxiway Of Civil Airport

End-Around Taxiway(EAT) is a new kind of taxiway used in airport with closely paralleled runways, and has an important value on avoiding or reducing aircrafts crossing the runway, as well as improving airport runway capacity and operational safety levels. The obstacle limitation surfaces of ICAO Annex 14, flight procedure limitation surfaces of ICAO DOC 8168 PANS-OPS(Air Navigation Services-aircraft Operations) and airport electromagnetic environment for EAT design requirements are studied in detail, giving the design methods of EAT and visual screen. Specific procedures and steps of end-around taxiway design are demonstrated combined with the actual situation of a large airport in southwest China, including necessity argument of EAT construction, design model determination, entrance forms selection, location and configuration determination, visual screen design and so on. EAT operation process is modeled and analyzed with the goal of minimizing time and EAT operation strategies are stated, which are crossing the runway immediately, waiting to cross the runway and using the end-around taxiway. Taxiing with EAT and using operation strategy could reduce overall taxiing time significantly compared with situations without EAT. Generally, with the improvement of peak hour flights and proportion of flight departures, the probability of using and dependence on EAT will increase.Using model analysis optimization method, EAT operation strategy of the airport mentioned above is decided and analyzed, proving the effectiveness of EAT and its operation optimization strategy. The software EAT-RDS is developed and provides a practical and convenient tool for air traffic controllers commanding taxiing in airports with end-around taxiways.
