1. En-route Working Group 22 Aug 2013

2. End-to-end Service descriptions • Transfer of Comm / Initial Contact • Key issues discussed in detail • Areas for further definition identified • Route Modifications • Excellent material from Harris, Lockheed, and FAA En-Route team • Key route clearance uplink issues identified • In time to work solutions aircraft test benches, within DCIT, and FAA design teams\ • We are on track for Use Case synching by end-Feb • Awaiting next Use Cases, but we are at that level within DCIT • Detailed messaging scenarios, over and above Use Cases will be worked jointly over the next few months per targets

3. Solution for Plenary Approval • If the result of the AFN Response (FN_RESP) message or the AFN Complete (FN_COMP) message is negative or not received ERAM will: • If a message assurance (MAS) fail ground message is received to NDA – Ground will retry one time • If negative or no FN_RESP – Ground system will retry one time • If negative or no FN_COMP - Ground system will ignore • If AFN Forwarding is unsuccessful - upon receipt by the aircraft of a Contact TOC and response from the flight crew or voice handoff to the new ATS service provider the existing NAS CPDLC will be termination. • If process fails aircrew is to use standard GOLD CPLDC re-logon procedures with the new ATS system provider • In the TOC/IC End-to-End • Any objections?

4. 2014 En-Route Risk Reduction Demo • Gregg outlined the current planning and process for the 2014 En-Route Risk Reduction Demo • Cooperation with aircraft operators and Flight Deck WG to establish information on areas such as trials constraints, goals and participation potential • Aim is to define the En-Route Risk Reduction Demo so that Program decisions can be made
