## Diversion Recovery Page

- This page shows the flights that are currently considered to be diversion recovery flights.
- This page is currently on the DataGate so it can be evaluated by the FAA and airlines.
- This page will when ready be moved to the ATCSCC web page so that everyone can see it.
- Features
- Diversion recovery flights currently identified in two ways.
- DVRSN in field 11.
- Automatic algorithm in ETMS.
- User can enter comments and a priority.
- User can sort on any of the seven fields and print.

## Issues

- Why is it so frequently the case that a flight is flagged as a diversion recovery by the ETMS diversion detection algorithm but DVRSN is not in field 11?
- Should flights only be fed to this page if they have DVRSN in field 11?  That is, should the diversion detection algorithm be turned off?

## Partial List of Planned Enhancements

- A command that allows a user to add a flight.
- Passwording to be required of anyone who wants to add a flight or enter a comment.
- Time stamping of comments and TCA acknowledgements.
- Fields to be re-ordered to match the order in an ETMS list request (ACID, TYPE, ORIG, ETD, DEST, ETA, ACENTR) and the DCENTR field to be dropped.
- Should ETE be added?
- What should be added or changed?

## Integrated Terminal Weather System

- The operational ITWS is to be deployed starting in 2001.
- Volpe will be providing a feed of the digital ITWS data to air carriers.
- Lincoln Labs will write software that will allow ITWS images to be displayed on a web site.  Volpe will host this web site.
- The prototype ITWS and TCWF displays will remain on the CDM DataGate as long as they are available.  They will be turned off when ITWS goes operational.
- TCWF is not currently planned to be in the operational ITWS that is deployed.
- It is time for carriers to discuss what they want on the web site.

## Planned Work on Flow-Constrained Areas

- Phase 1(November 2000, ready for testing): Capabilities for the TSD User
- FAA user can define an FCA
- Area (shown by clicking)
- Upper and lower altitude
- Direction of movement
- Speed of movement
- Start and end time.
- FAA user can see what flights intersect an FCA.
- Phase 2 (November 2000): Airline user can see what flights intersect an FCA defined by the FAA

## Feed of CTAS Data from DFW

- NASA is providing a feed of CTAS data from DFW.  This feed will include:
- Projected runway.
- Estimated touchdown time.
- Status
- System requirements document and interface control document are available to the airlines.
- Software by Volpe and NASA is written and is partially tested.
- The pacing item is that system testing cannot start until CTAS 5.5.3 is fielded; this will happen at the earliest in August.
- After testing is completed, the feed will be turned on.
- An air carrier needs to sign a MOA with the FAA to get the data.
- Carriers need to make sure that they have the needed bandwidth.

## Daily Download

- No recent activity.
- Work needs to get started again.

## SMA/ARTS Data

- Current TRACONs from which twenty-second position updates are available.
- Philadelphia
- Detroit
- Dallas
- Chicago
- New York
- Minneapolis (new in May)
- St. Louis (new in May)
- Atlanta (new in May)
- 30 June 2000: SMA/ARTS data to be provided in the TZ format used in the ASDI feed for Dallas, Chicago, and New York.

## Do You Have Enough Bandwidth?

- Changes in the pipeline that require bandwidth.
- One-minute TZs in the ASDI feed.  (Late2000-early 2001??)
- RVR (2001).
- CTAS from DFW (2000).
- ITWS (2001-2002).
- Common Constraint Situation Display (2000).
- Consult with your vendor to determine if you have enough bandwidth.

## RVR

- 8 June 2000: Telcon held with twelve airlines on RVR.
- 14 June 2000: Revised versions of the RVR System Requirements Document and Interface Control document distributed to airlines.
- January 2001: RVR data available from BOS and MEM.
- Spring 2001: RVR data available from roughly 45 airports.
- The RVR data will be available to the airlines in two forms.
- A digital stream of data.
- Tables and graphs on the DataGate.

## Revisions to the Digital Feed

- The feed will be available on three ports with three different update rates:
- 60 seconds.
- 10(?) seconds.
- 2 seconds.
- On the port with an update rate of two seconds, a client will have the option of getting:
- All data.
- Data only when there is a change.
- There should be an easy way for a client to indicate that it wants the RVR data from all airports.
- All of the revisions were made to the baseline documents.

## User Interface Constraints for the Web Site

- Airlines should be able to display a table of current RVR data for an airport and/or graphs of RVR data for the last hour at selected runways.
- Airlines should be able to display any mix of tables and graphs without wasting screen space or bandwidth.
- Display must allow for different size monitors being used at a variety of resolutions.  This means that the user should be able to control the amount of screen that is devoted to, e.g., the table of RVR data for an airport.
- The web environment has limitations.
- Use of bandwidth should be minimized.

## Sequence of RVR Screens

- When a user clicks on the RVR link for the first time in a session, a series of screens appears.
- Disclaimer: What you can use the data for.  “The data provided on this screen shall only be used for flight planning purposes.  The RVR data obtained form ATC is the official RVR.”
- Instructions: How to interpret the data.
- RVR Options: These control what the main RVR screen looks like and how it behaves.
- Main RVR Screen: This displays the requested RVR data.

## Notes

- The user can distribute tables and graphs among the cells in any way.  However, a particular cell holds:
- One table showing RVR data for an airport or
- Any number of graphs for a particular airport.
- The cells will be vertically resizable but not horizontally resizable.  To resize a cell, drag its boundary.
- If more data is requested than will fit in a cell, only part will be displayed, and a scroll bar will be shown.  If the user wants to see all the data, then the size of the cell should be resized.
- Tables do not take much bandwidth, but graphs do.

## Issues

- How often should a table update?  Suggestion: Once every five minutes.
- Should there be a “Toggle Screen Layout” button on the main RVR page to get rid of the items at the top of the page, i.e., the title, buttons, and color-coding?  That is, should one be able to toggle between pages with and without the items at the top?
- Should the restriction be imposed that only one graph can go in each cell?  Suggestion: No.
- What colors should represent touchdown, mid-point, and rollout?
- How should a table update if no data is currently available?  Suggestion: Show a blank for the interval where no data is available, but continue to show the valid data from the last hour.
