l The key to success is air/ground cooperation : n At standardisation level : ICAO ATNP, EUROCONTROL ODIAC OR and Design Teams, RTCA/EUROCAE WG 53, etc. n At development and validation level, thru air/ground integration programmes ä Collaboration with End users, Aircraft manufacturers, Avionics suppliers & communication service providers ä Example : EOLIA / Pro. ATN : ñ Cooperative demo at Le Bourget, June 1999 THOMFANS 11/21/2020 A 131 2104971/1 PPT Airsys ATM’s air/ground data link approach
l Validation of the products is done by different steps : n System development and unitary testing n Factory integration with the realistic tools : aircraft simulating tools, communication networks, radars n Integration with “adjacent” sites : ATC site & Simulator Aircraft n ATC site vs. Simulator aircraft / real aircraft ä FANS 1/A, EOLIA-Pro. ATN, DADI (Mode S) l For the ATN products, a special test bed is being created by the CAERAF project, to test air and ground Routers and End Systems THOMFANS 11/21/2020 A 131 2104971/1 PPT Validation approach

l ATC is faced with different a/g data communication means : FANS, ATN, STDMA, Mode S specific services l Different in functionality, integrity, performance, … some of them are already existing, whereas others may be complementary --> Opportunity l The (co-)existence of different air/ground networks cannot be neglected. Therefore, the integrated data link server has been embedded in Airsys ATM’s strategy. This strategy builds on the FANS 1/A - ATN Dual Stack approach THOMFANS 11/21/2020 A 131 2104971/1 PPT Data link introduction The difficulty -> opportunity -> strategy

l Minimises impact of data link introduction in ATC system, as the server takes care of part of the End User Application functionality, e. g. n managing the necessary Logon procedures n controlling the outstanding messages n acting as Aircraft Information Server for the ATC site l Optimises the air/ground data link medium to be used, taking advantage of the equipage of the aircraft l It offers a transparent interface. Any type of air/ground data communication means can be supported, whilst kept to the maximum extent transparent to the controller / ATC system l It can be connected to any type of ATC system 11/21/2020 A 131 2104971/1 PPT The data link server benefits THOMFANS

Conclusions A 131 2104971/1 PPT 11/21/2020 l Airsys ATM sees data link as a prime feature for new ATC/ATM systems. Hence its high involvement in R&D, Validation and Exploitation l The existence of different technologies cannot be ignored, … moreover one should take advantage of this l The integrated data link server enables a right introduction and seamless usage of multiple data links THOMFANS
