Where do Data Link Services fit in future ATM ?

Future of CNS and avionics – Communication

A/G Data Comm vs A/G SWIM services

Air-ground data comm services (e.g. B2)

are crucial for Trajectory Based Operations

CPDLC and ADS-C to ensure air-ground

synchronisation of aircraft business trajectory

Note: G/G SWIM is similarly a key enabler

Now is the time to ensure a consistent design of A/G Data Comm and A/G SWIM services

avoiding duplication and secure complementarity between contributing technologies

Emerging A/G SWIM services

(e.g. weather…) will address different needs/objectives

to be favoured for non safety critical information exchange in the short-term (cost optimization & flexibility)

• Advanced integration of CPDLC and ADS-C

with critical cockpit systems (e.g. FMS, TCAS,

RMP…) is the core added value of Data Comm

Crucial to secure strict air-ground interoperability,

relying on unambiguous and predefined message

formats and stringent certification requirements

CPDLC & ADS-C to support advanced cockpit integration

• Need for flexibility to accommodate potential evolutions in operational needs

- Use predefined CPDLC messages for instructions requiring cockpit integration, but

leverage on Free Text flexibility for others when needed

- Leverage on avionics modularity to limit impacts on complex systems (e.g. FMS)

• Harmonization of data link services is required

to ensure procedural consistency and avoid

operational fragmentation

Huge work already accomplished, still ongoing

and PBCS (Doc 9869) setting the performance based

framework

rial

A set of global and technology-independent

standards is available for operational services

Shall be the basis to pursue on the same path

especially confirming (or not) the need for

DRNP and IM services (more validation required)

• Harmonized deployment of underlying technologies to

avoid highly complex aircraft design and disproportionate costs

Unsuccessful efforts to align regional visions

(e.g. Europe / US) especially to clarify transition strategies

Network, i.e. when and how to transition from ACARS and/or

OSI to IPS (addressing cybersecurity risks and business case),

grandfathering of existing fleet

Links, i.e. VDL2 lifetime and transition to new terrestrial link

(LDACS?), introduction of new SATCOM links such as SBB or

Certus, need for AeroMACS …

Worldwide Data Link harmonization is a MUST 2/2

Aircraft cannot support a proliferation of technologies onboard

Need for a global technology deployment and decommissioning roadmap

globally endorsed by ICAO regions

• Initial Trajectory Information Sharing is a key building block of SESAR ATM Master Plan
