Objective: Proactive Management of the NAS without Over Control
❖ Distribute volume then reduce volume prior to route closure
❖ Anticipate airspace use and coordination – TRANSCON, CAN Routes, VACAPEs, etc.
❖ GDPs (variable rates) & Structured Routes verse AFPs/GDPs & Structured Routes
❖ Timely decision making and implementation
❖ Triggers driving action
❖ Exit Strategies
❖ Common Situational Awareness
Build on improvements
❖ Advanced Planning
❖ Departure Coordinator(s)
❖ ZNY anticipated Route telcon
Note: It is acknowledged that the impacts of COVID-19 to the aviation industry has been significant in 2020 & 2021. Traffic volume has been at
unprecedentedly low levels and will most likely not completely recover this SWAP season. However, even at lower than normal traffic levels,
these techniques can be utilized to maximize the throughput of the New York airports.

Focus Item –Special Emphasis, Advanced PlanningAdvanced Planning – Planning team will update the plan at ATCSCC D-1 eve update, mid update, D0 initial. Facility commitment to print/display plan
Trigger(s): N/A
Responsible Facility: ATCSCC / Facilities
Process/Considerations/Action

Planner is responsible for initiating discussion with facilities 2 hours prior to impacts.
TMI Planning will include analysis of arrival demand reduction to manage forecast departure route impacts and surface congestion
potential impacts. Facilities are encouraged to think strategically when discussing the arrival demand considering turn times, departure
bank impacts from convective impacts to departure routes, and potential surface constraint issues.

Focus Item – Route Closing / Opening Process
10
Process/Considerations/Action:
As weather constraints are anticipated to impact a route(s):
Use Weather Products – Short term forecast.
➢ NWS Gate Guide, CIWS, RAPT, etc.
Distribute volume then reduce volume using appropriate TMIs
➢ CDR’s, Playbooks, Route advisories, Capping, DUCT, SERMN, etc.
➢ Sample pattern: Low MIT → High MIT → Route Stop → High MIT → Low MIT → Normal operationsSpecific development/timing/volume may dictate a different pattern
When route closure occurs:
➢ Use Weather Products - CWIS, RAPT, etc. to estimate/anticipate decrease route constraint time and location
➢ ZNY Route Coordinator request TWR/N90 TMU advise #1 aircraft to resume using route and appropriate “High MIT”
Note: A line of convection along a front versus air mass cells growth and dissipation will impact confidence level and appropriate MIT.
➢ ZNY Route Coordinator coordinate #1 aircraft with TWR/N90, appropriate ARTCC and ATCSCC Departure Coordinator
➢ ZNY manages the process, coordination thru the TMU’s, ATCSCC Departure Coordinator, NTML entries, etc.
➢ ATCSCC Route Coordinator – coordinates route priority/needs with surrounding ARTCC’s & Stakeholders

Focus Item –AZEZU RouteAdvanced Planning: AZEZU route will be identified on the PERTI advance plan
Trigger(s): White volume and/or weather impacting J209/174 Responsible Facility.
Responsible Facility: ZNY/ZDC/ATCSCC
Process/Considerations/Action: Forecasts indicate that convective weather will impact east coast routes through ZDC and operational impact can be reduced by redistributing volume to other routes that are less impacted. Always issued as RMD due to aircraft equipage. Unless advisory is issued closing one of the AZEZU route elements, the route is available. The advisory is to encourage usage.
When beneficial for stakeholders, advisory will be published

can be reduced by removing volume from those affected departure routes.
Responsible Facility: N90 / ZNY / ATCSCC
34
Process/Considerations/Action:
