Topic 1: Data Acquisition and Dissemination–Air Traffic Control
Team
- Weather
- Most reliable source/ More accurate forecast
- Needs to be verified, e.g. planned for, never arrived (pilots/controllers)
- Longer forecast for planning (meteorologists)
- Traffic Situation Display (TSD) weather is valuable
- Volume
- TSD graphics useful
- Need to know reroutes to effectively manage resources
- Earlier warning (Traffic Management Unit–TMU)
- Complexity
- Information from controllers and pilots (current situation)
- Information from TMU (future time)
- Strategic plan
- Reasons for plan - big picture
- Need good way to communicate
- Need to be able to make controller understand
- Everyone should have the same information
- Availability of reroutes easier to get into computer
- Ability to display reroute plan, rationale and impact to controllers
Topic 2: Automation and Procedures–Air Traffic Control Team
- Tool that combines volume and complexity and gives indication (of
change/problem)
- More accurate Monitor Alert Parameter (MAP) numbers
- Means of expressing complexity in MAPs
- Need to explore methods to:
- Capture complexity numbers
- Validate MAP numbers
- Trial planner
- Reroutes overload sector, if so, then test moving traffic in affected
sector (off-loading)
- Shared information tool with:
- Information Distribution System (IDS), version 4/5 capabilities
- Weather information
- Miles-in-trail (MIT) information
- Approach plate information
- Real-time
- Highlight when something has changed
- Better weather display on Main Display Monitor (MDM)
- Procedures
- Need to consult with operational supervisor to verify constraints
in area. Get info from area before making rerouting plan. ("Keep
sup in the loop").
- Share planned reroutes based on future weather well in advance
- Operational supervisor can adjust area configuration/resources
or initiate traffic flow management (TFM) restrictions based on
area knowledge
- Procedure to issue reroute
- Sector with control of aircraft will read reroute to aircraft
(until controller/pilot data link communications [CPDLC])
- Automatic amendment to Host
Topic 3: Practical Application in Real-Time–Air Traffic Control
Team
- Identify weather problem
- Controller
- Relay accurate real-time weather-related information to operational
supervisor
- Operational supervisor/controller-in-charge (OS/CIS)
- Inform TMU
- Resolve small problems
- Initial reaction and solution to problem (short-term, tactical)
- TMU - facility-wide weather problem identification
- Air Traffic Control System Command Center (ATCSCC) - system-wide
weather problem identification
- Airlines
- Share information with ATCSCC to anticipate problems
- Pilots - Tell controller of intention
- Design reroutes
- Controller
- Provide feedback on what will/won't work in sector
- Take care of initial problems (e.g., deviations)
- Operational supervisor
- Pass controller information to TMU
- Collaborate with adjacent areas/ inform TMU
- Take care of small (now) problems
- Suggest reroutes
- TMU
- Take care of bigger (future) problems
- Plan bigger reroutes and share information. Involve affected
areas before implementing
- ATCSCC
- Coordinate when more than one facility involved
- Sometimes needs to exercise authority to implement route with
system impact
- Focal point for national implementation
- Airlines
- Keep FAA informed of routes required by Federal Aviation Regulations
- Share plans - information on cancellations/ substitutions
etc. most important priorities (to the degree it impacts weather/
reroute planning)
- Determine reroute capacity
- Controller
- Provide operational supervisor with information on what traffic
can be accommodated
- Keep operational supervisor updated (in general)
- Operational supervisor
- Based on controller input and TMU input on plan, determine
sector capacity
- Configure sectors, utilize resources and implement TFM initiatives
to maximize sector efficiency
- TMU
- Use automation tools (w/ accurate information) to determine
capacity
- Determine if reroute capacity is adequate for need
- ATCSCC - Mediate plans between adjacent facilities
- Assign specific flights to reroutes (depends on size of problem)
- Controller - work on aircraft in sector
- Operational supervisor
- Collaborate with adjacent area for aircraft in area
- Monitor impact/Make adjustments
- TMU
- Use tools available and make assignments
- Monitor weather
- Make changes
- ATCSCC - Collaborate with airlines
- Airlines - Collaborate with ATCSCC
- Implement reroute strategy
- Controller
- Reroute active affected flights; Scan Proposed flights for
compliance
- Operational supervisor
- Disseminate information to Controller
- Monitor Flow/ feedback to TMU
- Apply additional restrictions if necessary
- TMU
- Send reroutes to affected facilities
- Adjust reroutes as weather moves
- Evaluate feedback from operational supervisor
- Adjust restrictions as necessary
- ATCSCC - Act as liaison between facilities & airlines
- Airlines - File right routing
- Collaboration not needed/possible when:
- Unexpected weather develops suddenly; need to stop traffic
- Need to react to unsafe or time-critical situation
- Important areas for next step research
- Valid volume and complexity numbers (revised Monitor Alert platform)
- Weather forecast accuracy
- Reroute planning tools (research and deployment)
- More TSD capacity - more windows in areas slows system
- Common platform
- More shared automation allowing "information on demand"
