Collaborative Air Traffic Management
Collaborative Air Traffic Management involves National Airspace System (NAS) operators and FAA traffic managers, along with advanced automation, in managing daily airspace and airport capacity issues such as congestion, special activity airspace and weather. Updated automation will deliver routine information digitally.

Task Force: Integrated Integrated Air Traffic Management (ATM)
Collaborative Trajectory Options Program
This increment provides flight planners with information about congestion along their intended routes and allows the system to accept user preferences as part of constraint resolution. This is a two-way exchange that gives the flight planner the choice of delaying a flight or choosing alternate routes. The initial phase of Collaborative Trajectory Options Program is limited to the period before a flight plan is filed.
Task Force: Improve Collaborative Air Traffic Management (CATM) Automation to Negotiate User-Preferred and Alternative Trajectories (7b, 8 and 46) and Integrated System-Wide Approach (CDM/TFM/ATC) (47)
Route Availability Planning
Assessment of weather impact on departure routes and associated flights will be provided to tower traffic management coordinators and supervisors to improve departure operations.
This increment will be implemented via the Route Availability Planning Tool capability. This capability, coupled with Automatic Dependent Surveillance�Broadcast In, will be available to supervisory personnel and/or traffic management coordinators in Traffic Flow Management System (TFMS)-equipped towers.
Task Force: Integrated ATM and Data Communications
Execution of Flow Strategies
This capability is the means by which TFMS-generated reroutes are defined and transmitted via System Wide Information Management, making the reroute information available to air traffic control facility automation tools. This capability makes reroute information available for processing, but depends upon changes in the ERAM program to deliver the change to the appropriate sectors.
Delivery of Pre-Departure Reroutes to Controllers
This increment will give ERAM additional capabilities to receive amended routes pre-departure and provide updated flight data to the tower. ERAM will also display the protected route segment data to the en route controllers to make them aware of any constraints it affects.
Task Force: Improve CATM Automation to Negotiate User-Preferred Routes and Alternate Trajectories (7b, 8 and 46) and Digital Air Traffic Control Communications for Revised Departure Clearances, Reroutes and Routine Communications (39)
Collaborative Airspace Constraint Resolution
This increment recommends reroutes for flight-specific TMIs. An automated decision support tool models and proposes reroute solutions for pre-departure and airborne flights. It uses enhanced congestion prediction capabilities enabled by the integration of weather forecast data with existing and enhanced TFMS rerouting capabilities. Collaborative Airspace Constraint Resolution will allow NAS customers whose flights are predicted to encounter en route congestion due to weather (or other constraints) to submit inputs for constraint resolution.
