System Features CMU-900 Controller Pilot Context Data Link Management AOC Communications (CM) (CPDLC) Application Application Service Element (ASE) Dialog Service Airtel FastByte COPP ULS FastByte COSP AOC/AVLC COTP Satcom HF VHF Convergence Airtel AOC AOC AOC IDRP CLNP Function AAR Mobile SNDCF v8208 AOA SN-Map Satcom HFDR VDL VME/LME Mode A AVLC ARINC 750 Interface VDL Mode 2

  5. System Deployment • VDL Mode 2 testing performed in parallel with ATN development and test • Extensive lab testing of CMU/VDR/GTS • Rockwell Collins Sabreliner and Cessna aircraft • Flight testing against ground stations

  6. System Deployment • Airborne ATN Router (AAR) and Upper Layer System (ULS) • Airtel updates to support VDL and CMU environment • Airtel host testing • Integration of ATN and CMU software in simulator • X.25 Over TCP/IP (XOT) • Allowed End - End and ATN testing without VDL • ATN performed very well

  7. System Deployment • ATN port to CMU • Full end-to-end lab testing

  8. System Deployment • On-aircraft testing • Eurocontrol BAC1-11 • American Airlines 767 • PETAL Certification • Additional Interoperability testing has been performed with FAA and STNA/DGAC

  9. Lessons • ATN testing, integration, and operation better than planned • Test, Test, Test • Extensive lab testing from box level to end-to-end • On-aircraft ground and flight testing • Data capture • Team Coordination

  10. Next Steps • FAA Build 1 updates (2002) • Enhanced HMI alerting for ATN and CPDLC connections • Timer changes • PER Encoding (ATN PDR) • FAA Build 1A updates (2003) • Forward field of view ATC display • Essential level CMU
