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

What does integrated datalink mean?

•

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

ADS integration with Radar

•

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/FDP Integration for safety alerts (2/3)

Cleared flight Level Adherence Monitoring - CLAM

Comparison of current reported altitude with the CFL

ACARS

The ACARS network and FANS-1/A systems are expected (to continue) to provide dependable service for many years

2000 2010 2020 ATN ATN systems will need to be implemented earlier for high density airspace

Co-existence of the 2 networks

For at least Oceanic / non-radar airspace

IDLS Features

•

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

19

The data link server benefits

•

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

20

Thomfans

Conclusions

•

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 ...
