### FSM Changes for ETMS Overview

Miro briefed the group on the upcoming changes to FSM. Topics discussed
included:

-   Adaptive Compression

```{=html}
<!-- -->
```
-   GDP Process enhancements

-   GS defaults

-   Flight List enhancements

-   Airline coloring

-   Earliest AZ

-   Remove Data table

-   Bar Graph enhancements

-   Clear All alerts

-   Last code supporting C++ removed

-   Java 1.5 upgrade

Miro also briefed on pending ETMS 8.4 items:

-   Pop-up factor by hour

-   Disassociate AAR and Program Rate

-   Color schemes

-   Enhance Bar Graph adaptation

-   Open Data Set

-   Enhanced Windows Management

-   New Query Manager

-   Dynamic AFIX/DFIX coloring

-   Expand Pref sets to include FSM

Pat stated that unified GDP will not be in ETMS 8.4 but it is on the
wish list. It may make build 3 of TFMM (spring 2009). Some changes to
FSM after the 8.4 deployment are possible if they are germane only to
FSM.

### Training

Pat stated that the CDM Stakeholder Group (CSG) is favorable to training
and they want it to be of high quality. The CDM/GDPE will work with
Subject Matter Experts (SME) to develop the material; an FAA Lead is
needed. Jo D. would like the CDM public to have about 3 paragraphs
describing the GAAP and Snowbird processes. A refresher to the upcoming
season is welcomed. Pat will talk with DTO Doug Molin. There are no
other short/long term issues.

  -----------------------------------------------------------------------------

### Rolling GS

Pat would like to re-train DCC personnel in reference to moving into a
GDP from a GS. The NY airports are the hardest to convince. He has seen
the concept and it works and is predictable to end of the event. Towers
have a hard time keeping up with the GI messages for GSs, especially if
there are revisions. Pat has kept decisions at the NTMO/STMC level for
deciding when to remove the GS, based on a 40 minute lead time. Pat will
try to have any issues worked out by next severe weather season. Jim
Strouth stated that we could entertain feedback at the System Review
next month. Jo D. would like to see a breakout session there to discuss
delay process management. Charlie M. also agreed that we need to have
open discussions as to what the procedures should be.

All members discussed the issue of GS verses low-rate-GDP and the
predictability. There is a problem convincing some TMCs to start taking
aircraft before the AAR goes up. Pat will start to train TMSs and field
(maybe) during the winter. He is not sure how it will be handled yet.
Mike B. stated that Exempt Flights use to be able to take off and then
hold. Has GDPE considered revising the Exempt Flights, to take some
delay holding en route and some on the ground? Pat suggested that users
should make their statements on the SPTs with more authority. There are
no easy solutions to changing training and procedures, but pressure from
users will help accomplish this.

### AFP Usage

The group discussed how to use AFPs. DCC has 35 tactical AFPs that they
could put in at any time. They used FCAs that overly AFPs just to gather
data; some things didn't show up in HITLs. The AFPs will go to all NSST
positions. Rick O. said the first AFP that goes in overrides a later
one, unless it is told not to. Rick D. said that we need some new ideas
to deal with the number of Control Times (CT) issued to the towers. The
number of aircraft is the same; the number of CTs is the same, but
distributions of CTs vary due to the AFP. The Slot Credit Substitutions
decreased with AFPs.

In regards to future development of AFP, the GDPE will assume
responsibility only for the technical and automation aspects of AFP. The
FET will continue to work on procedural issues but the two teams will
meet periodically to work together on issues that overlap the two
workgroups.

### Data Quality Report Card

We need to take another look at the report card idea. We have a report
card for users, but not for FAA and ETMS. Rick O. stated that the report
card is formulated but is not disseminated.

### Advisories

Tammy stated that ADVZYs have inconsistent formats. Pat said that one
type is manual and the other is automated. ADVZYs for GSs are not
consistent and have strange terminology. Pat agreed that we could use a
template; sometimes "ZDC on internal GS" would be a manual ADVZY -- not
through FSM. In relation to ADVZYs not being machine readable, Dennis
stated that the lack of ability to capture cancelled flights is a big
issue on an AFP day. Rick D. also said that we need to be of one voice
in bringing our needs to CDM. We should have tested AFPs ahead of time
to give warning to ATC coordinators. Pat said that DCC is moving away
from ad hoc AFPs to tactical AFPs -- they will be able to see ahead of
time what issues may arise. Rick wants to find out what issues there may
be to getting a GAAP AFP.

### Future Issues for Consideration

Pat gave homework to the members for their consideration to future
enhancements to FSM. The items are:

1.  Unified GDP

2.  Training for delay management process

3.  CT updates to towers

4.  Modeling AFPs s/GDPs

    a.  The interaction between the two programs

    b.  Impacts

    c.  Purging

    d.  GS

5.  Data Quality Report Card

### Compression to Last CTA

Miro brief members on this topic so everyone knows how it works (see
link at beginning of document for more details). Based on logs and
comments, there is a need to re-evaluate the 'Compress to Last CTA'
logic currently implemented in FSM. The goal is to remind everyone how
this is implemented and determine if any change in software or
procedures is desired/needed based on changes in the operating
environment since original implementation. Topics discussed included:

-   GDP compression (within RBS++)

-   Pure compression

-   SI -- limited flexibility

-   Grover-Jack programs extended end to end

-   Less valuable slots issued in program extension

-   Current procedures and proposed new procedures

-   Options -- software, no software, other considerations

-   The Effects

### ETMS 8.3 Enhancements

Ken H. briefed the body on the upcoming changes to ETMS.

-   After this release, the goal is to freeze any changes to the Hub
    site to pave the way for TFM modernization

-   Starting with spring 2007, ETMS 8.4, there will be no enhancements

    -   Possible exceptions are receiving flight plans from FSS and
        receiving data from Euro Control.

    -   TSD/WSD/CCSD enhancements are allowed

-   GDP-related enhancements include:

    -   Adaptive compression (will not be enabled until impact on CTs
        has been assessed)

    -   New unsolicited messages

    -   GDP length reduction and GS scope reduction

-   FCA/Reroute-related enhancements

-   User pref-sets

-   Improve ETMS historical routes

-   There will probably be a ETMS 8.3+ around March 2007

### FCA, AFP, CT, Slots

The group discussed the use of slots, CTs, and how to let the tower
release aircraft based on what's in the queue. If a flight pushes back,
it might not take the slot of another higher priority flight that hasn't
pushed back yet. Having out-times and surface data would help determine
what slots are needed and how they move around. Use CDM message to
identify flights in a taxi status and freeze their EDCT. Pat stated that
we need to keep CT an issue in the loop for analysis. We could use SMEs
from ATL and/or ORD to come in and discuss -- Ken will write
requirements for developing a "tiger team" to discuss terminal
automation and more (ramp people). There is no way to keep track of how
much worse AFPs and CTs are making it for users. They can be impacted by
more than one program. We need more discussion on CTs and EDCTs with 30
minute parameters.

Ken H. stated that FCAs are created early in the morning and when a
flight routes out of the FCA, it looses its slot. A cancelled flight is
kept in the database. Pat asked if it's possible to cancel a flight but
retain the slot. Ken could consider cancelled flights along with real
flights when seeing where it crosses the FCA. You could set up FCA/AFP
23 hours in advance or a never ending one. Ken and Miro will set up a
test string to analyze. Ken will write up a summary. The members held
open discussions and brain stormed on route-outs, cancelled flights,
slots, and slots without EDCTs.

### Visit by CDM Leads and AJR-4

The work group was visited by Jim Ries, Lorne Cass, and Mike Gough. They
discussed the recent deployment of AFP and its impact and issues and
that the AFP work group will hand-off development responsibility to the
GDPE work group. Today, there are no clear answers to the problems but
we know we need to research tactical AFPs, multiple CTs, and new SOP for
AFP. They have gathered data from ATL and will look at CT messages. In
regards to Jo D's question about AFP training issues, Jim stated that
they will work with the Program Office to assemble a technical team to
handle CT issues. POET, FSA-PA will go web-based soon for the morning
briefs.

Bill C. suggested that we lay out a diagram of how things work to aid in
the resolution of the issues.

### Next 

The group plans to conduct a telcon on September 29 at 2pm, number to be
distributed at a later date. The next meeting is planned for November 14
at 1pm to 5pm and November 15, 7am to 1pm.
