Data Communications Program 2 Federal Aviation Administration January 12, 2012 Agenda Update on “Then As filed” Flight Deck Flow - Initial DCL Sample Clearances Review of DCIT #12 Discussion Items

Data Communications Program 3 Federal Aviation Administration January 12, 2012 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.

Data Communications Program 4 Federal Aviation Administration January 12, 2012 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

Data Communications Program 5 Federal Aviation Administration January 12, 2012 Flight Deck Flow - DCL Flight Crew Arrives at the Aircraft Requested AOC RTE Data, PERF Data, T/O Data and Wind Data is Sent to the aircraft and Loaded into the FMS – After Loading – FMS “RTE COPY” is selected if available Initiates Normal Pre-Flight Align the IRU’s /ADIRU and Initialize the FMS LOGON Received - KMEM – Aircraft on participation list Complete Normal Aircraft Pre-Flight ATC Comm Established Flight Crew Selects ATC Function Key or Menu select KEY - CPDLC Select “CLEARANCE” Request and “SEND” DCL Request Received - Approved DCL sent to the aircraft ATC Message ATC 30 Minutes prior to P Time Flt Plan correlation, DCL Approved and pending Flight Deck ATC Function AOC Function LOGON TO KMEM

Data Communications Program 9 Federal Aviation Administration January 12, 2012 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.
