  2. 4DTRAD Progress Report Day 1: position papers agreements • Changes to ADS-C EPP • Note to fields gross mass and predicted gross mass at TOD added • Field O added with notes: • o) Min/max speed schedule (optional capability) Note: The above data would be used by the ground system to assist in providing a solution to compute ETAmin/max. Either min/max speed schedule or min/max ETAs downlink must be made mandatory after the validation process. • Field P added with notes: • p) trajectory intent status data (optional capability)

  3. 4DTRAD Progress Report Day 1: position papers agreements • New contract definition • ETA min/max (Provides Minimum and Maximum estimated times of arrival at the requested waypoint) (optional capability) • a) Maximal estimated time of arrival • b) Minimal estimated time of arrival Note: The above data would be used by the ground system to assist in providing a solution to compute ETAmin/max. Either min/max speed schedule or min/max ETAs downlink must be made mandatory after the validation process. • We keep the ANEX C in the document • All changes coordinated with ADS-C group.

  4. 4DTRAD Progress Report Day 2: comments resolution • Closed 31 (document changed) including all showstopers • Working 5 (document to be changed) • Deferred 1 (validation discussion) • Rockwell Colins: necessity of vertical waypoint types in EPP needs to be analysed as part of the validation as it will be difficult to support those with some low-end FMS products. • Rejected 1 • Open 87 (mainly editorial) • Work required after the meeting
