A Global Approach

        - ICAO framework
        - EUROCAE/RTCA

Spectrum availability is also critical

Separating the Issues

Supporting Avionics

Physical Data link

‘Data com’ networking

‘Data com’ Services

VDL/2 transition to Future L band etc...

(FANS) , ATN/OSI transition to ATN/IPS

CPDLC, DCL, D-TAXI, i4D, etc ...

Retrofit and forward fit issues 

(FMS, Display, etc)

Deployment

Budget, mandates, timescales

It is important to separate out the ‘layers’ of issues in the question of Datacom.

The first level of harmonisation is a consistently defined set of services – including supporting trajectory operations. This is being done in the RTCA SC 214/EUROCAE WG-78

Operational Needs and the Datacom services

Reduce routine tasks and voice communication

Enable Initial 4D Trajectory Ops + additional services

Full 4D Business / Mission Trajectory

CPDLC:
        - ACL: ATC Clearance and Information service
        - AMC: ATC Microphone Check service

Supported by:

DLIC: Data Link Communications Initiation

ACM: ATC Communications Management
        - (European Datacom Mandate)

CPDLC Including:

D-TAXI: Data Link Taxi Service

CPDLC services supporting i4D

Enhanced position reporting providing future waypoints with time in seconds supported by ADS-C EPP (Extended Projected Profile)

Dynamic RNP and further applications currently being finalized

(Current scope of WG78/SC214)

Advanced ATM Services to be defined (Part of the work of SESAR in Europe)

+ Taking a fresh view of the requirements from a stakeholder needs perspective.

Technology  and Requirements

Technology development is a long term action (but must be expedited)

Operational Requirements not able to provide all of the detailed elements required for technology development

Requires an iterative approach with initial technical developments based on initial and early view of customers upcoming operational requirements

Possible FY17 Milestone

4D Trajectories (4DTrajectory DataLink (4DTRAD)), Dynamic  Required Navigation Performance (DRNP), Advanced Interval Management and D-TAXI.  

This version (V3) of the services roadmap addresses several items in the existing graphic:
          - Although the DCL Tower service was instituted during S1P1, it extends over the life of the program, so should be acknowledged as Tower Service for S1P1 and beyond.
          - Likewise for S1P2 EnRoute services, as a whole which will become the major part of S2 early on.
          - Avionics in S2 will be both B2 and FANS for quite a while.
          - The Baseline 2 ground system cannot be implemented as depicted in 2020 as the underlying standards are only being published in 2020, so we moved the implementation of the B2 ground system to 2025 to allow for the ground system to be built and aircraft to be equipped .
          - S2 consists of Baseline 2 services, so it was renamed from advanced services for more clarity.
          - S2 (B2) services include 4DTRAD which is the key NextGen Data Comm service enabling 4D Trajectories, and was missing from the existing graphic.
          - Advanced Interval Management is shown as generic; replacing the phrase “AIM – Arrival, Approach, Cruise, and Departure (AACD)” which might mislead readers into thinking that the Data Comm Program is implementing services in the TRACON in Segment 2.
          - AIM PTM was deleted as being an oceanic service so far - and anyway, there is no plan to modify ATOP to accommodate B2 and PTM.
