Agenda

• Update on “Then As filed”• Flight Deck Flow - Initial DCL• Sample Clearances• Review of DCIT #12 Discussion Items



Then As Filed

• Definition has been completed• At P-30, DCL will be made available for

request to the aircraft by an indication of a of ATC Comm Established message to the flight crew.

• If any revisions come through after the initial DCL, a UM79 or UM83 as appropriate will be sent to the aircraft.



Then As Filed

• Maintain Current Flight Deck Procedures for FMS pre-flight.

• When the Filed ATC Flight Plan “A” equals the DCL Clearance “C”, then the DCL Then As Filed clearance will be sent to the aircraft – It is incumbent that the

ARINC 702 Load matches the Filed Flt Plan

New Discussion Items• DCL Departure Procedure naming

– Departure Procedures using “RNAV SID” on the UM169 Free Text • Is this necessary? CLARE2.EIC RNAV SID OR CLARE2.EIC

– Recommendation…• Commas between each name e.g., CLARE2,SWB,RNAV,SID

– Recommendation… Remove the Free Text “RNAV DP/SID”

• DCL ALT information – Downstream Reroutes– Inclusion of Initial ALT on revised downstream clearances – UM83 e.g., Re-Stating

previously cleared information• Repeat initial cleared altitude with any trajectory change/reroute?

– Where is the initial DCL, How to ID the right clearance, is setting it in the ALT window enough?

– Recommendation… No need to repeat Maintain ALT for UM83/Downstream clearances.

• Enroute ATC Comm– Auto Session Establishment

• Typically for those areas where DCL ground service is not in use– DCL aircraft will maintain their ATC Comm connection and will be handed off to enroute

automatically• Adaptable parameter similar to the DCL termination action using Time

– Open discussion on ATN/FANS session initiations – ATOP/B1– Recommendations…(Start Point for Discussion) DM Time + X minutes to ensure session

establishment occurs at an altitude greater than 3000 AGL - local adaptation.
