7. AIDC/OLDI CPDLC/ADS CPDLC/ADS Radar/Flight Plan RDP/FDP Operational Implementation of CNS/ATM • Datalink (FANS-1/A) is no more at Trial stage but Operational • Need fully integrated Datalink with Radar and Flight Plan inputs • Stand alone Datalink Gateways do not meet full CNS/ATM benefits

8. AFTN, ICAO OLDI, AIDC MET ACARS ATN Radar 1 Radar 2 ... MMI MMI FDP RDP ADS/CPDLC Controller work stations …... Operational Configuration Dual LANs Training Configuration MMI Air Traffic Simulator Controller positions Pilot Positions Simulator Supervisor Positions Airsys ATM integrated CNS/ATM solution Use of Datalink not as a “nice-to-have gadget” but as an integratedtool to perform efficient Air Traffic Management

9. ADS used as an inter-active surveillance tool: Integration with FDP Integration with RDP for transition between Radar & non-Radar environment Use of next + N Waypoint information CPDLC used as an Air/Ground communication device, but also as an integrated Air Traffic Management tool: Integration with FDP to facilitate Flight Plan updates CPDLC link management Preparation of default values for the CPDLC messages Automatic Message posting (e.g. AIDC/OLDI/SYSCO) : For Coordination and Transfer of Control with Adjacent Centers What does integrated datalink mean?

10. No separate dedicated display for ADS and Radar all source of information (Radar, ADS, FP) available in a coherent display unique track displayed per aircraft (display priority Radar/ADS/FP) specific symbology to identify data source For Periodic contracts a specific offline adaptable contract is set to avoid frequent reporting during radar coupling. ADS integration with Radar

11. ADS/FDP Integration for safety alerts (1/3) ATCC flight plan route RAM corridor Positions received in ADS reports Aircraft trajectory RAM alert RAM Periodic contract • Route Adherence Monitoring - RAM • Comparison of reported position with the FDP Flight Plan Route

12. ADS/FDP Integration for safety alerts (2/3) CLAM alert CLAM Periodic contract CFL Altitudes received in ADS reports CLAM altitude tolerance Aircraft altitude evolution • Cleared flight Level Adherence Monitoring - CLAM • Comparison of current reported altitude with the CFL

13. ADS/FDP Integration for safety alerts (3/3) ARCW corridor ATCC flight plan route Aircraft predicted route received in ADS report ARCW alert ARCW Periodic contract • Aircraft Route Conformance Warning (ARCW = FLIPCY) • Monitors if the aircraft route follows the FDP Flight Plan Route

14. CPDLC - FDP integration Re-Route Example Load cleared route into FMS New route to pilot based on new wind data Request clearance expressed in lat/longs by CPDLC WILCO Airline AOC • Eurocat: • Visualise route proposed • Edit/revise • Eurocat : • FDP update • New route displayed • on the MMI • Conflict probe • Transmit clearance in lat/long New wind data

16. Co-existence of the 2 networks The ACARS network and FANS-1/A systems areexpected (to continue) to provide dependableservice for many years 2010 2020 2000 ACARS ATN ATN systems will need to be implemented earlier for high density airspace For at least Oceanic / non-radar airspace

17.

19. IDLS supports ATC datalink services on top of the comm. protocols IDLS implements the a/g comm. standards for your ATM platform IDLS uses standard ground communication protocols ASTERIX, ADEXP, TCP/IP, TP4, UDP/IP, X.25, ASN.1, … IDLS modular approach allows : Customisation for any type of ATM platform (En-route ATC, Tower, AIS, …) and AOC platform, Only those communication stacks required for the target operational environment need to be provided IDLS can be integrated with any type of ATM and AOC platform IDLS Features

20. Operational Benefits : Access to all kind of datalink equipped aircraft (FANS-1/A, ACARS623, ATN, ADS-B, ..) in the controlled airspace IDLS is field proven for FANS and ATN interoperability Respecting Airline and ATC investments in any air/ground communication technology Technical Benefits : IDLS allows ATN introduction in ACARS ATC centres with minor modifications IDLS enables a clear system architecture, allowing growth-potential to your ATM/AOC system and any new ATM/AOC datalink services IDLS dynamically selects the best air/ground communication link for each ATM/AOC service The data link server benefits

21. Airsys ATM provides today integrated CNS/ATM solutions based on ACARS and ground ATC systems, helping to get maximum benefit of air/ground datalink. Airsys ATM accommodates the transition from ACARS to ATN with … The IDLS, being the ATC Centre air/ground communication interface: supporting multiple air/ground communications respecting so ATC and Airlines investments enabling a clear and optimum ATC architecture … all being available and demonstrated right now ...
