RNAVによる到着・出発機の航法精度の評価

抄録

The evaluation trials for navigation and arrival/departure procedures using the RNAV(Area Navigation) function of FMS(Flight Management System), which is an onboard system of aircraft, were carried out in Japan. Lateral navigation accuracy for the aircraft which flew on the newly established arrival or departure routes for the trials was estimated on the basis of ASR(Airport Surveillance Radar) data. The result of the analysis on the trajectory of one hundred thirty-eight flights shows that all aircraft flew on every segment of the routes including curved route portions with a lateral deviation value of less than 1.0NM.
