  1. EWR DCL Trial UpdateCapt Gregg KastmanMD-11 Flt Trng Sup

  2. EWR DCL Flight Trials • MD-11: 27 flights conducted • Initial clnc (success rate 20/27, 74%): • 17 CAF, 1 UM79, 2 UM80s • 7 problems • Revised clnc after taxi (success rate 8/9, 89%): • 4 UM79s, 4 UM80s • 1 problem

  3. EWR DCL Flight Trials B-767: 2 flights conducted Initial clnc (success rate 100%): 1 CAF, 1 UM79 No revised route clnc after taxi Several 767 flights planned for October

  4. Summary of Problems FMC error (wrong tail # in AFN logon): 1 flight Resolution: Emphasize proper tail # for entry Automation update? Filing errors (local coding, modify FRC DCL): 3+ flights Resolution: Additional training provided to NY ARTCC, EWR Tower

  5. Summary of Problems DTAP reconstitution: 1 flight Resolution: Improve clock sync Notify AOCs for possible re-file DSP VHF radio frequency conflict: 1 flight Resolution: Frequency deconfliction Confirm EO applied to acft datalink equipment

  6. Summary of Problems Errors yet to be resolved: 3 flights AFN LOGON “REJECTED” (z-date 15 Aug) Clnc requested, “STANDBY” received (z-date 7 Aug, 21 Aug)

  7. General Observations • DCL Trials continue to be value-added • Uncovered pitfalls early on for: • ARTCC & Tower procedures • FMC handling of various messages • Flight Deck logon / message handling • DTAP hardware/software Suggestion: Continue Trial expansion. More airlines and more airports will each bring forward unique issues to consider.

  8. General Observations • Flight crew confusion on “DCL” terminology • Despite specific CPDLC instructions, they immediately think same as ACARS procedures internationally (Hong Kong, Narita, Cologne, Paris, Mexico City, etc.) • May be confusing for other international operators Suggestion: Create a distinct term for CPDLC DCL

  9. ACARS DCL in Cologne, Germany

  10. ACARS DCL in Paris, France

  11. General Observations • ATC hesitant to use DTAP during taxi • Most altitude/freq changes during taxi still via voice Suggestion: Continued practice; more participating aircraft should help make it habit for controllers

  12. General Observations • Although CAF is good for trial count, the ROUTE CLEARANCE makes DCL standout from PDC. • We need to continue testing UM79 / UM80s to identify: • Potential FMC problems (partial loads, joining STARs) • Potential printer issues • Potential flight deck human factors issues

  13. General Observations • Need to expand CPDLC UM capability: • Must have capability to join a STAR at any point • Even more critical for dynamic enroute ops • Should provide planned runway in DCL • Impacts how a SID is programmed in FMC • Provides CPDLC option to ATC for rwy change during taxi • If Oceanic controller can assign appr/rwy for TA, Clnc Del should be able to predict dept rwy • Should be able to print all messages • Invaluable comparison tool especially for legacy aircraft
