1. IP21 SIMULATION RESULT BY DARP FOR KSFO/KLAX (IPACG/40) ENRI

2. Background  DARP trial which has been carried out since August 22, 2013 brings some benefits.  At IPACG 38 and 39, ANA reported outcome from DARP trial of the arrival flight from PHNL/KLAX to RJTT/RJAA.  However, the number of flight applies DARP is not so many.  ENRI simulated the situation which almost flight tries DARP in the future for eastbound traffic.

15. Conclusion  DARP makes many benefits.  at 150E: larger benefit, but sometimes traffic concentration occurs. → low altitude  at 160E: smaller benefit, ATC operation is good.  Some flights assigned low altitude.  DARP from UPR  DARP from TRK  when: same Gatefix and closely location TRK & UPR
