2. Content Introduction The Criterion for EOSID RNP1’s EOSID Conclusions

3. Introduction CAAC ’s PBN Roadmap – Near term(2009-2012) 30% airports have the ability of PBN operations – Medium term (2013-2016) All transport airports have the ability of PBN operations – long term (2017-2025) Present situation –Total airports 196 –RNAV 23 –RNP APCH 59 –RNP AR 15

6. Criterion for EOSID Conventional Procedure RNP AR procedures

7. Conventional Protection Area 45° 900m 900+0.25D’ D’ D 900+0.125D 90m 12.5% 900m Initial protection area of departure Procedure turning protection area Departure Splay Area EU-OPS Heading change<15°  600m Heading change>15°  900m

8. RNP AR Protection Area 90m 12.5% 2xRNP RF leg protection area 2xRNP RNP-AR 0.3  1111m

9. RNP1 EOSID Protection Area Fly-over Fly-by Procedure turning area constructing model Out boundary not constant RNP 1  1111m

10. RNP1 EOSID Turning Area Constructing Fly-over waypoint –The earliest turning point =-ATT –The latest turning point= ATT+c Fly-by waypoint –The earliest turning point =-ATT+ R*tan(A/2) –The latest turning point= ATT+c- R*tan(A/2) ATT=0.8*XTT

11. RNP1 EOSID Wind Model Key point: Turning area changed by the wind factor Wind: ICAO wind: 30kt RNP1 reference Doc 9905 Consider the worse wind condition

15. EOSID Validation Simulator Validation –B737-700(22k) – Max weight, max temperature – Max weight, max temperature, max crosswind. – Min weight, min temperature, max crosswind. – Min weight, min temperature, max headwind. – Max weight, min temperature, max tailwind Flight Validation

17. Conclusions No specification or advisory circular about the RNP 1 on EOSID in China New wind model and RNP APCH turning construction model Simulator and flight validation prove the effectiveness
