Path I – Implementation of the DLS Transitional Solution

In accordance to the DLS Recovery Plan, SDM is coordinating and supporting Path I CEF Transport Calls 2016 proposed projects implementing both the Ground and Airborne requirements of the DLS Transitional solution in order to meet the Regulation (EU) 2009/29 deadlines.

On the ground domain, the multi-stakeholder project 2016_161_AF6 is working on the synchronized implementation of Model B or Model C with Multifrequency networks.

The project started in February 2017 (before the awarding decision) and is currently working on the Air-Ground and Ground-Ground Networks design. With regard to the airborne domain, 5 implementation projects have been submitted, with the aim of upgrading existing data link avionics for DLS to “Best-in- Class (BIC)”.

According to its mandate, the SDM has continuously guided, supported and synchronised the activities of the project in full coordination with all the involved implementing partners; moreover the SDM is monitoring the status of the implementation of the DLS transitional solution according to existing monitoring mechanisms already in place for the Deployment Programme.

 

Path II – Preparatory activities towards the Target solution

Complementing the results that will be achieved through Path I implementation, a Path II multi-stakeholder project was submitted. The project scope is to support SDM in its role of DLS implementation project manager for the definition of the activities necessary to reach the implementation of the target solution (Model D), ensuring a common reliable and agreed framework.

According to the EC mandate and the ELSA recommendations, the SDM in close cooperation with the Path II project (started in March, before the awarding decision), is performing the following activities:

  1. Requirements collection and Service Areas definition
  • Status Update: the SDM, taking into account the main elements for the deployment of the ELSA study findings and the related proposed scenarios included in the Path II project deliverable, has performed a detailed analysis from which a proposal for the Service Areas definition will be derived. The related draft “Service Areas proposal” has been elaborated by SDM and submitted to Stakeholders Consultation Platform and SDM Cooperative Arrangements (CA) for consultation on 26th May 2017. This first round of consultation will lead to a subsequent consolidation of the SDM Service Areas Proposal expected by the end of July. In this document, the SDM proposes a two steps approach: a first step, consisting in the Model D implementation through two Service Areas, and a final one, consisting in the Model D implementation through a single Service Area at European level.
  1. European technical architecture definition
  • Status update: taking into account the main results highlighted by Path II project related deliverable and starting from the Service Areas defined in the previous task, the SDM is defining the DLS technical architecture at Service Area and European Level.
  1. Elaboration of a Business Case for the target solution
    • Status update: following the Path II – KOM on the Business case held in London on 13th and 14th June 2017, the SDM has started to perform preliminary activities for the evaluation of costs and benefits brought by Model D implementation.
  2. Transitional activities towards target solution:
    • Status update: the SDM will identify the future steps and activities for the transition from the models deployed at Country/Region level towards the target solution throughout Europe.
  3. Ensuring consistency of activities related to DLS Governance definition:
    • Status update: the SDM is in charge of monitoring the DLS Governance establishment (in order to ensure its consistency with the DLS strategy), which is under Path II stakeholders’ responsibility (whose KOM has been held in Langen on 6th April 2017) and currently running.

Building on the outcomes from the Path II project, SDM is developing and consulting a proposal to DG MOVE on [items 1 to 4 above] to be delivered by end of September 2017. Subject to stakeholders’ buy-in and robustness, DG MOVE may decide to use this proposal (or part of it) as guidance for the DLS priority into the next CEF Transport Call.

 

Complementary activities

According to the DLS Recovery Plan and the EC mandates, a set of complementary activities are expected to be carried out by NM, EASA, and EUROCAE in order to ensure a synchronised and coordinated DLS implementation throughout Europe. To facilitate their execution, the SDM has enhanced the cooperation among the different involved Bodies, through the organisation of transversal meetings and the definition of a joint action plan, with the aim of addressing the main issues pointed out in their specific mandates.

Specifically, the following topics are in the process of being addressed by EASA, in cooperation with SDM, EUROCAE, NM and other stakeholders as applicable:

  • – Short-term review of Regulation (EC) No 29/2009 on DLS, that evaluates the criteria for exemption (automatic and per type) and potentially amendment to the existing decisions on exemptions. It also addresses various other topics including the latest ICAO amendments relevant for DLS, provisions for non-AOC traffic operators. A focused consultation on DLS exemptions has been organized with various stakeholders;
  • – Launch of the RMT.0524 (clarification on the BIC avionics, implementation of Model D and end-to-end certification) with an expected NPA by the third quarter of 2018 and an opinion by the end of Q2 2019;
  • – Identification of possible gaps in terms of applicable standards to ensure IoP between airborne and ground systems including a proper way to implement multi-frequency. Furthermore, EASA will develop guidelines in support to NSAs for an harmonized approach for fulfill in a proper way the requirements of IR 552/2004 (for example DoV production)
  • With respect to best in class it is acknowledged that a revision of the ED-92C addressing the ELSA report, would be too late to be pragmatically implemented by 2020. Therefore, as the risks (in terms of a possible minimum gap between ED-92B + best in class upgraded avionics and ED-92C reflecting formally ELSA outcomes) are acknowledged by the airspace users, SDM current campaign of upgrading the avionics units to BIC (compliant with ED-92B) is continuing. EASA will review the BIC as part of the RMT.0524 and assess the need to upgrade the minimum certification standards to reflect the future revision to ED-92C in work with EUROCAE.

According to its mandate, the Network Manager, in cooperation with SDM, has performed the following actions:

  • – Establishment of the DPMF, replacing the former Central Reporting Office (CRO) that was providing datalink support so far; the DPMF aims at reinforcing DLS monitoring campaigns and collecting the required data to meet the EC demand for the regular publication of the DLS Key Network Performance Indicators;
  • Cooperation with all involved actors for the performance data gathering;
  • Provision of network data analysis to support the regulatory processes related to the “Best-in- class” avionics;
  • – Analysis and focus on the DLS Real Time Monitoring

Furthermore, in terms of cooperation with EUROCAE, it is worth highlighting that ED-92 is used in the baseline for the certification of the avionics systems and a dedicated EUROCAE working group WG-92 has been setup to essentially maintain the current ED-92B version up to date and synchronised with VDL standard. Specifically, the following activities have been carried out so far by EUROCAE:

  • – Review of WG-92 Terms of Reference, together with the establishment of a concrete roadmap for a progressive updating of ED-92 standard;
  • Collection and resolution of the issues arisen by VDL Mode 2 implementers taking as reference ED-92B;
  • – Impact analysis on ED-92 deriving from other VDL standards update (i.e. ICAO, ARINC …).

 

Upcoming DLS Workshop

In November it will be a year since the European Commission (EC) has organised a worskhop on the state of play on DLS. This year, the EC will update all stakeholders again by organising a new workshop on DLS in autumn in Brussels. The workshop will be on the 17th of November. A detailed programme will come soon.
