Dear IPS participant:

Honeywell has prepared the strawman for Supplement 1 to ARINC 858 Part 1, IPS System Technical Requirements, and the strawman for ARINC 858 Part 2, IPS Gateway Air-Ground Interoperability, based on responses to action items and the conclusions of the December 7-9, 2021 meeting. See message from Mike Olive below.

This material will be discussed in detail at the upcoming IPS Subcommittee meeting to be held January 25-27, 2022 (Tue, Weds, Thurs) online.

Your comments in writing before January 25 are greatly appreciated.

Best regards,
Paul
