2 2 Fundamentals of PBN (RNAV / RNP)

3 Fundamentals of PBN (RNAV / RNP) 3 Kinds of Navigation Conventional ü Route consists of Navigation Radio Station (VOR, DME, NDB, ILS and etc) PBN (Performance Based Navigation) ü RNAV or RNP ü Route consists of waypoints, which are independent from Navigation Radio Station

4 Fundamentals of PBN (RNAV / RNP) 4 Conventional vs. PBN

5 Fundamentals of PBN (RNAV / RNP) 5 RNAV defined in PBN RNP (Required Navigation Perf) Onboard perf. monitoring and alerting system required RNAV (Area Navigation) Onboard perf. monitoring and alerting system NOT required En-Route Terminal Approach En-Route Terminal RNP4 RNP2 RNP1 RNP APCH RNP AR APCH RNAV10 RNAV5 RNAV2 RNAV1

6 Fundamentals of PBN (RNAV / RNP) 6 1 RNAV defined in PBN RNP Terminal RNP 1 En-Route Approach RNP 2 RNP 4 RNP APCH RNP AR APCH RNAV RNAV 1 RNAV 2 RNAV 5 RNAV 10 N/A

7 Fundamentals of PBN (RNAV / RNP) 7 What is RNP XX / RNAV XX XX NM XX NM For RNP APCH, XX = 0.3 NM For RNP AR APCH, XX 0.3 NM

8 Fundamentals of PBN (RNAV / RNP) 8 What is Onboard perf. monitoring and alerting system For example: ANP: 95% Navigation Accuracy In of case FMS GPS Position. signal XTK Error: Deviation from the invalid... intended route FMS Position The ANP increases and exceeds the RNP, then Message(Alert) is shown in cockpit. True Position

9 Fundamentals of PBN (RNAV / RNP) 9 Conventional vs. PBN (Odate Noshiro) From Tokyo RNP AR Approach OdateNoshiro Airport Circling Approach

10 Fundamentals of PBN (RNAV / RNP) 10 Conventional vs. PBN (Saga) Saga Airport Yanagawa City

11 Fundamentals of PBN (RNAV / RNP) 11 Summary of PBN l Improves Flight Efficiency ü Shortest route results in less CO2 emission and shorten flight time l Improves Flying Rate ü Instrument approach for runways without navaids, which allows to land with worse weather conditions l Improves Air Traffic Control ü Separations between aircrafts can be reduced, which results in increment of flights

12 12 Fundamentals of GLS (GBAS Landing System)

13 Fundamentals of GLS (GBAS Landing System) 13 Fundamentals of GBAS Kinds of Approach 13 Non-Precision Precision VOR LOC / LDA ILS (LOC, G/S) Circling RNAV / RNP RNP AR GLS (GBAS)

14 Fundamentals of GLS (GBAS Landing System) 14 ILS (LOC, G/S) Localizer Glide Slope GLS (GBAS) GPS GBAS

15 Fundamentals of GLS (GBAS Landing System) 15 ILS (LOC, G/S) GLS (GBAS) SPD IKN/335 DME 6.8 ILS LOC A/P G/S SPD G34B/335 RW34R 6.8 GLS LOC A/P G/S L IN L IN GS185 TAS o / WA2A z 0.8 NM GS185 TAS o / WA2A z 0.8 NM TERR 6 TERR TFC A KBFI TFC A KBFI ADF L SEL HDG MAG GPS ADF R PWT ADF L SEL HDG MAG GPS ADF R PWT

16 Fundamentals of GLS (GBAS Landing System) Fundamentals of GBAS RNP to xls (ILS vs. GLS) l CAT-III vs. CAT-I ü Currently, GLS is only available for CAT-I (DH 200ft, 550m RVR) while ILS is available for CAT-III (DH=0ft, 50m RVR 175m) ü In future, CAT-III GLS will be available l Flexible Final Approach ü Final approach course for GLS can be shorten than one for ILS, which contributes to establishment of flexible approach course with RNP

17 Fundamentals of GLS (GBAS Landing System) 17 Fundamentals of GBAS RNP to xls (RNP AR vs. GLS) l Non-Precision vs. Precision ü RNP AR approach is non-precision approach, and can t be used for bad weather conditions such as CAT-I(-II,-III) ü GLS is precision approach, and autoland is available l No special training required for xls ü RNP AR approach requires special authorization, which needs flight crew training with simulator every year. On the other hand, GLS doesn t require additional simulator training 17

18 glide slope Fundamentals of GLS (GBAS Landing System) 18 Summary of GLS l Similar to ILS ü Flight crew procedures and cockpit indications are almost identical to ILS l Waiting for CAT-II/III Operation ü CAT-I is available, but hope to implement CAT-II/III operation in near future l Improves Flying Rate ü Runways, that can t equip ILS, may be able to equip GLS, which improves possibility of landing in bad weather conditions
