3 1.ADS/CPDLC ATC SYSTEM ATS Datalink Central Reporting Agency
4 Oceanic Sector with Electric Strips and CPDLC Display at Tokyo ACC 1. ATS Datalink and its usage
5 Oceanic Traffic Situation Display used at Tokyo ACC
6 ADS Position Displayed on ATC Screen Tokyo ACCs Oceanic System 1. About ATS Datalink
7 2. FIT CRA and RASMAG
8 Whats FIT ? FIT Structure IPACG/ISPACG FIT (FANS Interoperability Team) Report 2. FANS Interoperability Team CRA (Central Reporting Agency) U.S. and Japan provide CRAs for FIT.
9 RASMAG Regional Airspace Safety Monitoring Advisory Group / APANPIRG RASMAG is a group responsible for airspace safety monitoring in Asia/Pacific airspace regarding; ATS DATALINK Monitoring RVSM Monitoring RNP Monitoring
10 Who are stakeholders ? FIT is the datalink specialists work group of ISPACG & IPACG Representatives of all these parties below participate in this activity: Air Traffic Service Providers Aircraft Operators Aircraft and Avionics Manufacturers Datalink Service Providers(DSP) ATC Systems Manufacturers States Regulatory Authorities International Organizations 2. FANS Interoperability Team
11 What are FIT responsibilities ? The FIT(FANS Interoperability Team) oversees the monitoring process to ensure the ATS datalink system continues to meet its performance, safety, and interoperability requirements and that operations and procedures are working as planned. FIT is responsible to: review Problem Reports and determines resolution develop interim operational procedures monitor progress of problem resolution prepare summary of problems assess system performance authorize and coordinate for system testing 2. FANS Interoperability Team
12 Whats CRA ? CRA: Central Reporting Agency is an organization tasked with the regular dissemination of de-identified information on: statistical performance data based on Periodic Status Reports prepared by ATS providers, and Problem Reports sent from stakeholders and their processing status & rectification progress 3. CRA Activities
13 ATS Datalink Central Reporting Agency 3. Example of Problem Reports Problem Reports 3. Example of Problem Reports Problem Reports
14 An Example of Problem Reports Improper CPDLC Position Report FMS Database includes non-ATC waypoints and provides pilots with these information. A Pilot downlinked CPDLC Position Report for Non-ATC Waypoint. When repeated, it increases pilots and controllers workload and communication load. Operators were requested to educate pilots to send ATC Compulsory Reporting Point only.
15 An Example of ADS Problem Reports Emergency Reports from Non-Emergency Aircraft When a pilot operates EMERGENCY SELECT ON or EMG Button, ADS EMG Mode is engaged and the avionics downlinks emergency messages. ATC System receives it and display the aircraft identification with EMG Tag on ATC screen. However, actually the aircraft was not in emergency. Supposed to be pilot s mishandling of ADS. Manufacturer took a remedial action.
16 Weather Example : WX Deviation with Heading Mode Planned Route NEXT WAY POINT 21NM Actual Flight Path Flight Direction and Position Displayed on ATC Screen Abnormal aircraft positions and flight directions may be displayed for an aircraft on ATC screen, when the pilot selects Heading Mode for weather deviation, instead of FMS Offset. Heading Select
17 VHF Coverage Fringe Area VHF Coverage Satellite Coverage Space DSP sends MAF (Message Assurance Failure) to ATC Center ATC uplinked a message to aircraft Aircraft downlinked acknowledge, but failed, because of out of VHF coverage. VHF ? SATCOM ??... No acknowledge from aircraft
18 Central Reporting Agency Activities Central Reporting Agency Activities 4. Operational Performance Performance 4. Operational Performance Performance
19 Nature of Traffic in Tokyo FIR Average Number of Traffic in Tokyo Oceanic Airspace (September 2003) 442 aircraft per day Average Number of Successful CPDLC Connections (September 2003) 127 aircraft per day CPDLC Connection shares about 29 %, and about 50 % for North Pacific.
20 Trend of Number of Successful CPDLC Connections Mar Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug Sep Oct 2003 Number per Day Monthly Average / March 2002 – October 2003
21 System Performance Analysis CRA analyzes System Performance based on monthly statistical reports sent from ATS providers. It includes statistical data of : - Delay time for Round Trips - Delay time for Downlinks - Number of lost messages - Unavailability of systems - Connection success and failure 3. Activities of CRA
22 CPDLC System Performance No. of MSG 95Percentile 99Percentile Trip Time (h:mm:ss) CPDLC Downlink 95 & 99 Percentile, 9/2002 – 8/2003
23 CPDLC System Performance CPDLC Uplink 95 & 99 Percentile, 9/2002 – 8/ Jan Feb Mar Apr May Jun Jul Aug No. of MSG 95Percentile 99Percentile Trip Time (h:mm:ss)
24 ADS System Performance ADS Uplink Message Success Rate 9/2002 – 8/2003 Number of Uplink Messages / Month
25 Website Web-site is available for any participants who sign the confidentiality agreement. CRA provides lessons learned experienced by other pilots and controllers on CPDLC/ADS operation. It includes useful information for pilots & controllers and system engineers. 3. Activities of CRA
26 Address of JCABs CRA Please send your Problem Report to: For Website: But to be accessible to Problem Reports or Performance data, you are requested to sign Confidentiality Agreement 3. Activities of CRA
