## Reroute Advisory Tool

## Project Goals

- The Reroute Advisory Team was formed with the goal of improving the clarity and usefulness of reroute advisories issued by the Air Traffic Control System Command Center.
- Among the activities of this team was to investigate how a list of flights affected by a reroute could be appended to an advisory. This was identified as a high priority enhancement since it would go a long way toward removing ambiguity both for NAS users and FAA field personnel.

## Project Goals

- Provide a list of aircraft to be considered for reroutes, attached to an Advisory for ATCSCC reroutes. This allows system users and facilities common situational awareness for a reroute.
- The flight list will be provided to system users and FAA facilities to accurately depict what flights are included in a reroute. This creates the opportunity for system users to participate in the pre-departure phase of the reroute process.
- Develop the capability to parse flight specific, route specific information. This is a necessary first step towards the development of further automation tools.
- Reduce the amount of advisories received by Users and FAA facilities by tailoring the addressing in Autosend. This will allow for advisories to be parsed to facilities only included in the reroute for the advisory issued. This will be developed in the Summer and implemented in Fall of 2003.

## RAT RESPONDER

- The RAT responder has not yet been developed.
- The team is exploring possibilities for incorporating
- technology to allow for industry response to reroutes.
- This would be similar to substitutions that are currently
- In use for Ground Delay Programs.

## Procedures

- FAA facilities are responsible to ensure flights are on the required reroute prior to leaving their area of responsibility.
- System Users will be asked to explore the possibility of taking responsibility for rerouting their flights prior to departure. Currently, 45 minutes prior to aircraft push-back from the gate is being discussed as a cutoff point for them. After this point, the FAA would assume responsibility for the reroute.
- This allows for system users to depart from the gate with full authorization for the flight to be able to accept the reroute. It would also allow for better ETMS data for the FAA facilities, letting them examine demand for routes and sector volumes in a more timely manner.

## Schedule

- Begin testing sample format messages with FAA field facilities.
-     in mid December, 2002.
- Testing will be necessary 3 days per week. Monday, Wednesday and Friday.  0800-1600 EST will be identified testing periods.
-     This schedule will begin December, 2002 and be completed.
-     by February 30th, 2002.
- Solicit feedback from FAA facilities for the following categories:
- 		1. Accuracy of data received in the RAT flight list.
- 		2. Format of the received advisory and RAT flight list.
- 		3. Content of the advisory and RAT flight list.
- 		4. Usefulness of the RAT flight list in your operations.
- 		5**.**** **Collaboration and understanding of your needs and
-                limitations.

## Schedule

- Deploy the initial operational version of RAT in ETMS 7.*6.       *This will occur in spring 2003.
- Use RAT to send flight list advisories with Transcon Playbook    reroutes. The initial implementation will be for Transcon reroutes that have at least 1 hour of lead time prior to commencement of the reroute. This allows for users to participate in the process of route planning.
- Expand the use of RAT throughout the Summer to include all
-     Playbook reroutes.
