Tailored Arrivals Ops Monitoring Tag-Up

Approved for release to non-U.S. persons. Export Management Log #ARL-07-DWS109


Objective of health monitoring
Objective of health monitoring

  • Ensure that the trials systems and procedures are meeting trials aims

  • Ensure that changes in usage levels are quickly understood, as a means of capturing lessons and potential problems

  • Ensure that problems are identified and resolved quickly

  • Ensure that resolutions meet the intended purpose, and do not create new problems

  • Give visibility to operational parties, and trials management, on how their contribution is working for them and the trials

  • This is not the same as

    • Benefits tracking

    • Officially reported statistics

    • These two items need more time to create and approve


Monitoring package starting trials 2007
Monitoring package (starting trials: 2007)

  • 4-7 Dec (hoping we don’t need 7 Dec … will decide on 6 Dec)

    • Greg Saccone / Kevin Elmer: quick stats on previous day UAL74 & UAL870

    • Ops around the room: NCT, ZOA, UAL

    • Proposed date / time: 12:30 PM PST

  • 10 & 17 Dec (both Mondays),12:30 PM PST

    • Weekly telecons , same format but more flights!

  • 22 Dec – 7 Jan: ad hoc ADS-C sampling; no noise sampling

  • 7 Jan: reconvene weekly telecons, 12:30 PM PST

    • Drop to bi-weekly as soon as verified running smoothly

  • Attendees (Ops Authorities and Trials Authority are mandatory)

    • UAL (Rick Shay or delegate)

    • FAA (Rich Lanier or delegate)

    • Oakland Center (Ed Wilson or delegate)

    • NCT (Rick Cote or Patty Daniel)

    • Boeing (Rob Mead or delegate)

    • The entire team has been invited

      • 35% full TAs

      • 65% partial TAs

  • Observations

    • Total request numbers up from last period

Around the room
Around the room

  • UAL: NTR

  • ANZ: would like to see more full Tailored Arrivals (seeing <25% right now, e.g. 3 of 14 the last week)

    • Rich L. reports: NASA has just initiated analysis to see if they can find trends in the partial vs. full Tailored Arrivals, to see if they can identify potential causes

  • ZOA:

    • Encoding issue encountered 29 April, resulted in discontinuation of TA clearances

    • Fix identified and tested against Boeing Test Benches 1 May

    • TA clearances to restart Tuesday, 6 May

      • Until 6 May, controllers will “unable” request, appending e.g. “will restart Tuesday”

  • NCT: NTR

  • JAL: still a few weeks away from starting

    • "Datalink Handbook" explaining TA procedure is done

    • "Operations New " explain general concept of TA is in draft.

    • Rob will communicate start-up date when available

  • Noise: still no noise complaints; benefits analysis from Kevin in progress


Implementation of agreed changes

  • Procedure Baseline is “TA_procedure SFO_v9b.doc”

  • Today’s changes, plus the following changes already promulgated via e-note

    • Being fully implemented in ANZ and UAL FMB updates, 1st/2nd week Jan

    • Crews will request the TA once at least 45 minutes prior to oceanic exit.

    • More standard speed management by crews

      • Crews will use 280-300kts

      • 180 knots from FAF – marker

    • Use of speed restrictions by Oakland Center, to improve full TA possibility

      • If possible, at least 10 min prior to TOD, the Oakland Center radar controller will issue an “Expect descent speed of 280 knots” advisory

      • Controller will later instruct this speed using phraseology “Descend via the uplinked route clearance ALPHA at 280 knots”


Summary of health monitoring format

  • Completed in the Ops Management telecons

  • Quick and up-to-date stats

    • Basically, last week’s stat’s, thru Friday, available on a Tuesday

  • Ops around the room

    • Ops leads report/drive discussions; minimal non-ops input

    • Gauge operational health of the system

    • Advise problems for joint resolution (near-term and more permanent fixes)

  • Review of implementation date(s) for previously agreed problem resolutions

  • Op Leads from each organization are mandatory participants

    • For TAs, everyone was welcome unless it caused problems (it never did)

  • Meeting records should go out the day of the telecon


Health monitoring statistics for dcl
Health monitoring statistics for DCL?

  • Number of eligible flights

  • Proportion of eligible flights that logged-on

  • Proportion of eligible flights that requested a DCL

  • Proportion of eligible flights that received an initial DCL clearance, and what type of initial clearance was received

  • Proportion of eligible flights that received one or more revised DCLs, and what type of revisions they were

  • Proportion of flights that wilco’d, unabled, or standby’d clearances

  • Round trip times (clearance to wilco)

  • Number of logged-on flights that received a DCL via voice instead of datalink
