1 B1 Backwards Compatibility CSG October 2012, Long Beach, CA, USA F. Picard, EGIS AVIA

2  CSG Actions from P15  P15-5 : Should B1 BC requiremens moved into a separate standard ?  P15-6 : CSG to provide a table(s) to correlate each possible operational configuration with the applicable Interoperability document sections(s). (This may include updating the “red/blue/green” diagram).  P15-7 : How does the CPDLC ASN.1 reflect the BC requirements ?  A CSG review of INTEROP Part 3 is required  Only 7 comments received P-15 Maastricht June 12

3  BC material can be moved easily in a separate document, annex or stay in PU-20  2 sections have to move into PU-20 Part 1 (Introduction)  Identification of DL Systems  FANS 1/A  ED-100A / DO-258A  B1  ED-110B / DO-280B  IMP B1  European SES DL Implementing Rule  Identification of DL Configurations Action P15-5

12 P15-7: ASN.1 B1B1 B2B2  Solution #1: One single ASN.1 Module in PU-20  including all B1 and B2 messages  Used partially by B2 only systems  Each implementor extract the relevant part  Solution #2: Two ASN.1 Modules in PU-20  One B2 only ASN.1 PU-20 used by B2 only systems  One B1 + B2 in Acc. used by B2 systems accommodating B1 IMP  Consistency issue B1B1 B2B2 B2B2

13  Rules for accommodating REPORT REQUEST from the ground when the datalink REPORT is not supported by the B1 A/C:  The ground sends a REPORT REQUEST  The Pilot responds by WILCO and the dialogue is “technically” closed  When conditions are met, the flight crew will provide the REPORT using voice  Is acceptable to initiate a dialogue via Datalink and to provide the requested “Data” via Voice?
