8. Current State: NAS Operations
Flight information received by combination of airline schedule data & filed flight plans
Information is supplemented by departure and arrival messages, position reports etc.
Information usually not updated until after the fact, creates a lack of awareness throughout the system, resulting in trajectories which are not always current
Airspace User is unsure of the actual departure and arrival time which negatively impact gate assignments, passenger connections, crew and aircraft rotations
Airspace User, airport and ATC planning is negatively affected due to lack of accurate position reports and times
ATC
Is monitoring aircraft track
Has latest arrival time
Has updated TMI which may be causing delays
Does not have immediate access to airline filed delays
AOC
May not have current track
Is not provided with updated arrival times
Must file delays manually with DLA message
Is not alerted to holding, metering, fix balancing or in trail restrictions.
Arrival
The intent of this slide is to help drive engaged discussion to identify the range of considerations in the current state
We want to be sure we capture the hottest issues to the community for the written use case, and reference for future exchanges
Landing / Taxiing In
September 7, 2018

9. Problem Statement Present State
Aircraft departs on Time
ATC is receiving live updates on aircraft while AOC experiences a delay in obtaining current information
Updated arrival times are continually created based on factors affecting flight
Aircraft arrives per time predicted by ATC
Departure
En route
Arrival
ATC Perspective
Aircraft departs on Time
AOC receives delayed information from ATC and may not be aware of updated arrival times
Aircraft arrives later than planned
AOC works to reallocate ground resources to handle late aircraft
Backup on taxiway due to unplanned congestion in non movement area causes delay on ground
Departure
En route
Goal is to have engaged discussion around the problem to determine root cause
Want to engage the producer to help reflect a common understanding of the problem we’re seeking to solve

10. New Reality Based on New Information Service
Future State
Aircraft pushes back
AOC receives notification of aircraft pushback
AOC receives updated surface movement, surveillance data and estimated departure time
AOC receives departure time
AOC receives continuously updated schedule route and aircraft position data
Delay information, route, speed, altitude changes are communicated as they happen.
Changes to SAA activity are communicated in real time.
International flight data available
AUs will have clear picture of flow programs (metering, fix balancing, MIT, etc.) impacting arrival time
AOC is able to reallocate ground resources as needed based on accurate flight information
Airport staff are able to better plan for identified delays
Surface congestion is minimized
Departure
En route
Arrival
Slide intended to show what happens with getting access to data
What does ATC/AOC operations look like, generally, with access to this new data
Slide shows how the information service, with all the data elements, is now available and what the implications are
It may be of value to coordinate this slide with a producer

11. Future State: Future NAS Operations
Once flight pushes, information continually shared so all users have same updated data
Airline schedules & flight plan information will be continuously updated via SWIM with current schedule, route and aircraft position data and sent to ATC / airports
Collaboration with ATC will be improved because Airspace Users, Airport and ANSP all have the same accurate picture to manage resources
As changes occur during flight (e.g., route changes, speed and altitude changes, SAA, etc.), updates continue to be shared with Airspace Users & airports
Airspace Users planning for gate usage, fleet management, crew resources is improved with precise arrival data
Airport planning will improve with current operations picture for traffic using airport
Slide intended to show what happens with getting access to data, as it pertains to the specific operation we’re talking about
This describes the operation in the future, now with access to data

12. Benefits of Improved Flight Data
Improved Flight Data and Sharing of information with stakeholders will allow Airspace Users and airports to know precisely when aircraft will depart and arrive. This enables:
Improved decision making concerning aircraft fuel efficiency
Improved diversion management
Improved gate management
Improved flight crew management
Improved ground crew management
Improved delay management
Improved fleet management
Improved customer experience
Improved TFM system performance
Improved airport effectiveness
This slide is intended to identify the anticipated benefits associated with our understanding of the solution
Goal is to identify some way to validate the magnitude of the improvement seen with the benefit
Intent of this slide is to validate these and identify whether there are additional benefits not identified here

13. Many Objectives, One Mission: Flight Information Data Driven Real-time Decisions & Post-Ops Analysis
Air Traffic Control:
Responsible for safe and efficient use of airspace, maximizing airspace use and runway efficiency
Success is defined by maximum use of runways and airspace, effective strategic planning, and minimal use of tactical interventions that add delay to flights
Airline Flight Ops:
Responsible for ensuring regulatory compliance, ensuring on-time operations, managing gate and crew resources, maintaining flight schedules, fleet management, and applying the airline business model
Success is defined by predictable on-time operations, adherence to schedules, effective gate, crew, and fleet management. End result is a positive customer experience.
Airports:
Provide a safe environment for flight and surface operations, provide ramp control, ensure airport resources are available (runways, taxiways, ramps) at times that meet Airspace Users and ATC requirements.
This identifies the metrics and initiatives they identified for us during the first meeting, that could be addressed this solution
I want them to see how we’re linking what’s important to them to what we’re providing them with the data sets

Data Service
A service which provides access to source data
Business Service

17. TFMS-Flight, STDDS-SMES/TAIS, SFDPS-Flight/General Flight Data
Flight Data is comprised of data from a variety of systems but the main source of input data is En Route Automation Modernization (ERAM). TFMS, SMES, TAIS, TFDM and TBFM have a consolidated view of the entire system and adds value to that information. The resulting output is an accurate reflection of the state of the NAS in terms of traffic flow management. Flight Data is sent as it is updated, when there is a commanded change, or when there is a computed change.
Message Name
Description
Track Information
Track Information messages are used to provide a position update for the identified flight. In cases where the track position causes a route re-conformance (trajectory modeling) additional route data is provided. The messages are transmitted as received by TFMS on a cyclic basis.
Flight Plan Amend Information
The flight Plan Amendment message provides revised flight plan data as the result of a flight plan being successfully amended.
Arrival Information
Arrival Information Message is used to provide arrival date and time information for all eligible arriving flights.
Departure Information
The Departure information messages is transmitted for all eligible initially activated flight plans.
Flight Plan Information
The Flight Plan Information Message is used to provide flight plan data for all eligible flight plans.
Flight Plan Cancellation
Flight Plan Cancellation messages are used to provide cancellation data for all eligible flight plans when a cancel message is received from the Host/ERAM or IADE interface or an operator action associated with the schedule database that causes previously Schedule Activated flights inserted into the NCSM to be canceled.
Boundary Crossing Update
Boundary Crossing Update is used to provide TFMM with current flight plan information on active eligible flights that are inbound from one ARTCC to another ARTCC facility.
Oceanic Report
Oceanic Report Type provides flight information for transoceanic flights and is generated when an Oceanic Position Report is received via NADIN.
Special Activities Airspace
The SAA message provides schedules and status of SAA activity
General Information
A general information message is used to communicate a free-form text message and remarks.
Hold Status Information
The Hold Status Information message provides hold information (holding fix, and estimated fix departure time for definite-duration holds) on all active aircraft
STARS data
STARS status sent periodically (nominally every 60 seconds) and upon change of any published fields
