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.

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.

Trigger(s):

❑ Day of Operation forecast Weather/Convection to impact ZOB arrival flow into N90.

❑ Actual Weather/Convection development impacting ZOB arrival flow into N90.

Responsible Facility: ATCSCC Planner / ZOB (trigger)Process/Considerations/Action:

- Conference ZOB / ATCSCC / ZNY(N90) / ZBW approximately 2 hours prior to route impact. Coordinate impact actions.

- Reduce/distribute incremental volume from N90 arrival flow(s) LIZZI/PENNS/LENDY as Convection Impact develops –

move to ZBW either tactically or via playbook

- Move specific city pairs ie. ORD, MDW, DTW, MSP…

- As routes close move flows to ZBW / (ZDC)

- Exit strategy – route reopening

Responsible Facility: All

Focus Item – Route Closing / Opening Process

Page 10: Northeast Throughput Plan 2021

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

Responsible Facility: ATCSCC / ZNY / N90

Common Situational Awareness – Exit Strategies Process/Considerations/Action:

❑ Use pathfinder process as a guideline or common operating practice.

❑ Process is an operating method / guidance / consideration, a variety of situations may require adjustments.

➢ Forecast for a line of convection will include a higher level of confidence then airmass convection movement. TMU actions/decisions need to be adjusted based on confidence and changing situations.

31

Focus Item – SWAP Statement / Hotline

Trigger(s):

Hotline should be initiated prior to departure route impacts.

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

Route needs to be filed – ATC is not aware of equipment (life rafts, etc.)

Page 33: Northeast Throughput Plan 2021

Focus Item –SERMN Route(s)

SERMN (Swap Escape Routes – Metro New York Area)

Advanced Planning: N90 Towers - SERMN routes will be identified on the PERTI

Trigger(s):

❑ Low altitude routes used when operationally beneficial for volume and/or weather

can be reduced by removing volume from those affected departure routes.

Responsible Facility: N90 / ZNY / ATCSCC

Page 34: Northeast Throughput Plan 2021

34

Process/Considerations/Action:

❑ SERMN routes are used to reduce enroute fix/route volume and distribute to lower Tower Enroute Clearance (TEC) structure
