摘要

Air traffic flow management (ATFM) initiatives are applied when the projected demand exceeds the capacity of an airport or sector. Aircraft can be delayed before their departure at the origin airport (ground delay) or after they are airborne (controlled enroute delays). The remaining delay is absorbed by path stretching (vectoring) and/or speed control. Since such "uncontrolled" airborne delays are expensive in terms of fuel burn and cause high air traffic controller workload, ATFM tries to minimize the amount of vectoring while maintaining maximum throughput. Japan has been running a ground delay program since 1994, but to further optimize traffic flow management, controlled enroute delays (CFDT) will be introduced in 2020. This study evaluates the potential effect of CFDT on air traffic flow into Tokyo International Airport (Haneda Airport), the busiest airport in Japan. In particulate, we develop a numerical simulation considering flight time prediction uncertainties and CFDT compliance rate (crew acceptance rate) and evaluate the ground, CFDT and airborne delay and for each set of control parameters. Preliminary results show that CFDT decreases ground holding delay and contributes to more equity in delay distribution, but uncertainties involved in daily operations might make it difficult to collect sufficient data to prove this effect.
