## Problem Identification

**Coordination and communication of gateway reservation information**
**Need for latest Gateway Reservation List (GRL)**
**DOTS+ Track Advisory (TA) employs cumbersome, text-message interface for air carrier users**
**Concerns that GRL is not updated**
**Users have limited insight into TA decision process**
**GRL must be repeatedly requested to check for updates**
**Air carrier users perceive that TA is inhibiting their ability to depart at desired time**
**Users have limited information on gateway availability changes once flights depart**
**ATCSCC (FAA Command Center) manually assigns departure times to Towers for ZAN tracks**
**Forecasts for significant increase in oceanic traffic**

**Notes:**
Track Advisory (TA) is a computer based program that is designed to assign altitude and time for oceanic departure release for aircraft on specific oceanic tracks based on airline preferences. It is accessed by airline operators and FAA facilities outside the oceanic Traffic Management Units (TMUs) by an AFTN/NADIN II command-line interface. Track Advisory assigns each flight a time and altitude at the oceanic gateway fix.  Based on the gateway fix time, the flight is also assigned a departure time. These times are listed in the Gateway Reservation List (GRL) which is sent to users.

## Proposed Solution

**DOTS Plus Online**
**user-friendly, online interface to DOTS+ Track Advisory**
**secure web server front-end**
**early demonstration of System-Wide Information Management (SWIM) concepts**
**DOTS Plus Online (like TA) will primarily be used to coordinate gateway times/altitudes in the pre-departure phase**

## Benefit  Awareness

**DOTS Plus Online will improve coordination and communication between various TA users**
**Air carrier users**
**Improved interface – more likely to update information**
**Updated GRL automatically displayed**
**Additional gateway information**
**Estimated gateway times updated based on actual departure times**
**Departure information**
**Automatically sent to Center TMU, reducing ATCSCC workload**

## Operational Concept

**Capabilities in 2004 Prototype**
**Web-based interface**
**Secured sign-on procedures**
**Templates and saved gateway requests**
**Format and logic checks**
**Real-time updated Gateway Reservation list**
**Customized Gateway Reservation list**
**Acid**
**Requested Departure time**
**Requested Gateway Time**
**Assigned Track/ Crossing Fix (Gateway)**
**Departure airport**
**Arrival Airport**
**Assigned Departure Time**
**Assigned Gateway Time**
**Assigned Altitude**
**Assigned Track**
**Metrics/Archive of latest state of information**

**Additional Capabilities**
**Slot availability (pre-departure)**
**DOTS+ Online/ETMS interface**
**Departure time information forwarded to Domestic TMU**
**ETMS Departure time forwarded to DOTS+ Online**
**Additional columns in GRL for users to view **
**Requested Altitude**
**Requested Track**
**Actual Departure Time**
**Estimated gateway time. **
**Update estimated gateway time based on actual departure time (no change to reservation, but shows how close flight is expected to make reservation)**
**Capability for user to update estimated gateway time**
**Remarks (local to user) **

**Basic DOTS+ Online based on capabilities in 2004 prototype plus some additional capabilities**

## Implementation Plan

**Target: Operational demonstration for ZAN operations in first quarter FY08**
**April 2007:  Requirements definition completed.  Internally coordinated (FAA ATCSCC, ZOA and ZNY TMUs)**
**April 2007: Coordinated with NavCanada**
**July 2007:  Coordinate with Airspace Users**
**In Progress**
**prototype development**
**review and evaluation**

## Open Discussion

**General - How do airspace users currently use Track Advisory?**
**Single or multiple dispatchers send in their Gateway request**
**Gateway reservation is complied with in planning and/or shared with pilot**
**User Messaging Requirements**
**Would you call other users and the TMU or would you prefer e-mail or chat capability**
**Options:  E-mail, Chat, Forum**
**Track Information Page - Is there additional information that would be useful to airspace users?**

## Open Discussion (Continued)

**Gateway Reservation Request Capability**
**General feedback on process**
**How entries are validated**
**Gateway Reservation List**
**What information is not useful**
**Any other information that may be useful**
**Filter - Do you want to see all tracks and all flights or just specific tracks and own flights only?**
**Sort - Do you want different sorts?  How many?**

## Open Discussion (Concluded)

**Graphical Display**
**Feedback**
**What “estimated GW time” should be shown, and is this a window **
**GRL Modify**
**Feedback on modifying gateway request capability**
**Are you able to determine when slots are available?**
