Data Communications DCIT Update Flight Deck Working Group Presented to: DCIT #12 Plenary By: Andy Fry, Thane Inc. Date: January 12, 2012 Federal Aviation Administration Agenda • • • • Update on “Then As filed” Flight Deck Flow - Initial DCL Sample Clearances Review of DCIT #12 Discussion Items Data Communications Program January 12, 2012 Federal Aviation Administration 2 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 January 12, 2012 Federal Aviation Administration 3 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 January 12, 2012 Federal Aviation Administration 4 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 TO KMEM LOGON Received - KMEM – Aircraft on participation list Complete Normal Aircraft Pre-Flight 30 Minutes prior to P Time Flt Plan correlation, DCL Approved and pending •ATC ATC Comm Established Select “CLEARANCE” Request and “SEND” AOC Function Flight Deck ATC Function Data Communications Program January 12, 2012 ATC Message DCL Request Received Approved DCL sent to the aircraft •Flight Crew Selects ATC Function Key or Menu select KEY - CPDLC Federal Aviation Administration 5 “Then As Filed” – MCDU 2 1 0 5 z Flight Crew Displays the ATC DCL Message C L E A C L A R MA I N E X P D E P .

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.
