technical issues
Technical Issues

CPDLC (5)

showstopper: Error / enhancement in ASN.1

No LINK backwards compatibility for [route clearance] parameter

ACM (2)

Document differences between normal and abrupt CPDLC connection termination (End vs. Abort)

No latency check on downlink system messages (e.g. DM99 CDA)

DCL (8)

Inconsistency SPR / IOP

Messages in DCL requests (a/c type, prefered level, departure frequency…)

ADS-C (7)

showstopper: single or multiple RTA ?

Emergency status in ADS-C contract reject message ?

Level defined twice in ADS-C report

Fixname replaced by Waypoint Identifier in ADS-C report

« Lateral Type » values, EPP parameter optional/mandatory attributes not consistent with SPR

SNOWTAM (1)

ASN.1 definition of SNOWTAM report (close)

ITP (1)

Alignment with ED122 Change 1 proposal

PICS (1)

Errors detected in CPDLC PICS

documentation management issues
Documentation Management Issues
  • Traceability
    • SC-214 INTEROP Requirements to ED110B/DO280B IRs
    • SC-214 FANS Accommodatrion Requirements to ED-154/DO-306 Requirements
    • Question to Plenary: confirm the need for such traceability.
  • Document Naming
    • Names required for SC-214/WG-78 documents (e.g. « PU-40 » before ED-154 publication)
  • Document Versions
    • Several version conventions for SPR (letter), INTEROP documents (major/minor release) – Decide on way and document in José’s WP.
  • Document Configuration Control
    • Wide distribution of defects and defect resolutions
    • Need for a formal Configuration Process
      • Comment matrix is not sufficient
      • Formal PDR (Proposed Defect Report)
    • Need for establishing a CCB before validation starts
    • Need for a dedicated mailing list and/or a PDR data base (e.g. bugzilla)
validation process 2010 s 214 issues
Validation Process (2010) – S-214 Issues
  • Need to define a Validation Plan with Validation Objectives covering all documents (SPR, IOP, Tech Specs)
      • Functional Validation Objectives (VO)
      • Technical Validation Objectives (TO)
      • Document/Specification Validation Objecftives (SO)
  • Need to define Validation means and Validation level
    • Paper Review
    • Implementation of Prototypes by 1 or more than 2 independant initiatives
  • Consolidate a Validation Report
    • From validation reports sent by validation initiatives
    • Validation Coverage Analysis
    • Validation Assessment and Statement
week output
Week output
  • No separate INTEROP meeting – Common working sessions with the SPR SG. Issues and resolution are the one reported by SPR SG.
  • 32 new comments have been raised. Editors have clear instructions how to handle these comments. Should be done by January. No showstopper for INTEROP.
  • The DCL issues for FANS accommodation have been addressed in the DCL session and are closed.
  • CPDLC PICS are up to date.
  • Material for CPDLC is now stable.
  • Work remains to be done is to align the INTEROP doc with the decisions taken this week on ADS-C
