New York Center operates up to five (5) manual departure positions in a centralized Departure Complex (also known as The Pit). The Complex is overseen by the Departure Director (DD [TMC]) and issues clearances for traffic departing all New York and Philadelphia metro airports. Due to the proximity of high density airports and the commonality of route fixes, the centralization of the Complex provides the Departure Director with advance warning of route or fix saturation. Judicious and timely reroutes are employed to mitigate or avoid bottlenecks, eliminating or reducing departure delays. During periods of high airspace complexity or severe airspace constraint, the Complex is invaluable in rerouting aircraft.

Sector 57 [Show]

• Sector 57 issues amended routings to Philadelphia (PHL), McGuire (WRI), and satellites.
• When directed, issue alternate route clearances for aircraft departing PHL/WRI and satellites.
• Monitor all systems for routing errors and proactively issue correct route clearances.

NOTE: This is the primary Departure Complex position.

Sector 59 [Show]

• Sector 59 issues amended routings to Kennedy (JFK), Islip (ISP), and satellites.

N90 TMU

Supervisory Traffic Management Coordinator

• Maintain continuous awareness of traffic demands and TMIs.
• Establish N90 Airports’ Arrival Rates (AAR) and Departure Rates (ADR).
• Direct and support TMCs in resolving conflict.
• Report equipment issues to the OMIC.
• Provide an overview of anticipated demand, impacts, TMIs, and weather at all operational briefings.
• Participate in the Strategic Planning Telcon (SPT) as required.
• Log all TMU actions in NTML.

Traffic Management Coordinator

Work under the general supervision of the N90 STMC.

Keep the STMC informed of the current and projected demand, TMIs, runway changes, and delays.

Notify the STMC when delays reach +15 minutes, and every 15-minute increment thereafter.

Maintain a record of traffic management actions.

Balance arrival and tower enroute flows through coordination with appropriate ARTCC TMUs and adjoining facilities to ensure that demand does not exceed system capacity.

Coordinate with towers and TRACONs to establish the AAR and assist the ARTCC and adjacent facilities in developing strategies to achieve the AAR.

Oversee departure fix balancing to ensure sector efficiency into downstream facilities' airspace.

NOTE The appropriate ARTCC shall be the focal point and mediator between terminal facilities. Further, N90 is uniquely situated between three ARTCCs, thus N90 should coordinate directly with the vATCSCC who will then conference the appropriate ARTCCs. In the case that the appropriate ARTCC TMU is unable to resolve a dispute, vATCSCC has the final decision-making authority.

TMAC

Arrival Coordinator
This position is responsible for ensuring smooth, orderly, and effective flows can be safely maintained for traffic arriving at N90 airports.

• Work under the general supervision of the N90 STMC.
• Analyze demand, airport capacity, runway configurations, overflow capabilities, and operational conflicts * to determine the need for arrival TMIs.

• Use TMA arrival timelines to determine release times for internal departures to the metered airports.
• Monitor TMA timelines and advise adjacent facilities or the N90 STMC of non-compliance meeting TBM times.
• Log all TMA actions in NTML.

General

Line of Authority

• Rather than having an additional Traffic Management Officer (TMO) position to manage and direct the ZNY and N90 TMUs, the STMC assumes those responsibilities. Due to the unique setup of N90, it is treated as its own facility with an operational TMU. Likewise, ZNY has its own TMU, both of which interface with the vATCSCC. When traffic management related issues cannot be resolved by appropriate administrators, vATCSCC has final decision-making authority.
• In the absence of the STMC, the position may be delegated or fulfilled by the Events Coordinator, Air Traffic Manager (ATM), Deputy Air Traffic Manager (DATM), or otherwise delegated official. In the absence of all members and any potential delegate to the position, vATCSCC will assume traffic management responsibilities until no longer needed or until the appropriate roles can be filled.

Traffic Management Training

Traffic management training may be accomplished via appropriate facility procedure or through a combination of facility-specific training and vATCSCC coursework. All certifications remain the sole responsibility of the traffic manager’s home facility.

Inter-facility Communication

• At all times, utilize to the extent practical, collaborative decision making techniques.
• Maintain constant situational awareness and utilize all tools and resources available to you.

Intra-facility Communication

New York Area Hotline

• Phone Numbers and Resources:
  • vATCSCC Discord Link
  • vATCSCC Ad Hoc Hotline
  • (646) 307-1990 (DCC join.me Dial-in Conference)
• The objective of the Hotline is to provide rapid communications between air traffic facilities, customers, and other aviation interests when complex air traffic and airspace issues are being managed. Hotlines allow many participants the capability to problem-solve complicated issues and reduce the amount of coordination needed to implement collaborated strategies.
• The STMC must initiate and participate in telcons and Hotlines with facilities and customers, as necessary, to obtain input and to provide operational information, as well as to manage other significant events affecting airspace.
• Advise neighboring facilities if an operational Hotline is requested or active.
• The Hotline will be used to communicate:
  • Airport and airspace capacity issues
  • Constraint/capacity mitigation strategies
  • Route availability information and route alternatives
  • Weather information
  • Equipment Outages
  • Customer preferences for initiatives and alternatives
  • Special circumstances, contingency requirements, and emergency events
• All required coordination and information sharing necessary regarding the event.
• All parties must leave their microphones muted while not speaking and identify themselves using proper interphone format when conversing.
• Coordination that can be accomplished quickly and precisely with all parties. If an item requires extensive coordination, other communication sources may be used.

The following is an Operational Planning Checklist and includes all the areas that must be covered in an OP:

• Review the current weather constraints
• Review pertinent facility topics
• Input from the Areas
  • Staffing
  • Sector Combination
  • Anticipated Initiatives

  • Internal and external TMIs
  • Route closure/reroute information
• Anticipated Traffic Management Initiatives
  • Alternatives
  • Triggers Needed
  • Exit Strategy Needed

Traffic Management

It is important to remember that TMU does not mean controlling traffic. Rather, it is managing traffic flow. It is not TMU's job to maintain safe separation, adhere to strict phraseology, or provide control instructions; however, it is responsible for the actions it takes.

ZNY PIT positions are sometimes required to give amended route clearances and must use proper phraseology and air traffic control techniques.

The entire traffic management effort must operate as one and constantly use collaborative decision making processes to ensure equitable solutions to traffic management problems. Equitable is different than equal in that the best solutions are used to combat problems rather than one solution applied to all users. Traffic management is a dynamic in nature and requires quick thinking, strong communication/collaboration abilities, and extensive knowledge of the airspace system.

Traffic Management Initatives

Miles-in-trail (MIT)

The number of miles required between aircraft that meet a specific criterion. The criterion or qualifier may be separation, airport, fix, altitude, sector, or route specific.

Minutes-in-trail (MINIT)

The number of minutes required between successive aircraft.

Implementation

• The ZNY Enroute Coordinator (EC), N90 TMDC (when departure restrictions are in effect), or N90 TMAC (when arrival restrictions are in effect) must notify the STMC, the providing sectors and affected controllers of the restriction.
  • Controllers must acknowledge with their operating initials.
• The ZNY EC, N90 TMDC, or N90 TMAC should enter the restriction into the National Traffic Management Log (NTML) and, as appropriate send a message containing the restriction through the ATC Channel or other coordination channel.
• The STMC will notify any affected neighboring facilities of the restrictions in place.

Cancellation

• The ZNY EC, N90 TMDC, or N90 TMAC must notify the STMC, the providing sectors and affected controllers of the cancellation.
  • Controllers must acknowledge with their operating initials.
• The ZNY EC, N90 TMDC, or N90 TMAC should cancel the restriction through the NTML and as appropriate send a message containing the cancellation through the ATC Channel or other coordination channel.
• The STMC will notify any affected neighboring facilities of the cancellation.

NOTE: MIT of ten (10) nautical miles or less must not exceed four (4) hours.

Utilized to segregate different flows of traffic, or to distribute the number of aircraft requesting access to a specified geographic region.

• Colloquialisms:
  • Tunneling – term to indicate traffic will be descended prior to the normal descent point at the arrival airport to remain clear of an airspace situation; e.g., holding.
  • Capping – term to indicate aircraft will be cleared to an altitude lower than their requested altitude until they are clear of a particular region.
  • Low Altitude Arrival/Departure Routing (LAADR) – a set of routings with altitude expectations for usage during periods of severe weather.

Implementation

• The ZNY AC (tunneling or LAADR), ZNY DC (capping or LAADR), ZNY DD (capping or LAADR), N90 TMDC (capping or LAADR), or N90 TMAC (tunneling or LAADR) must notify the STMC, the providing sectors, and affected controllers.
• The ZNY EC must advise the affected controllers of block altitudes to use for different fixes and may also assign specific aircraft altitudes.
• Controllers must acknowledge with their operating initials.
• The ZNY AC, ZNY DC, ZNY DD, N90 TMDC, or N90 TMAC must send a message to all facilities via the ATC Channel or other coordination channel advising that Tunneling, Capping, or LAADR is in effect, and should enter a restriction into the NTML as necessary.
• The STMC will notify any affected neighboring facilities of the current restrictions.

NOTE: Altitudes are subject to conforming traffic flows.

Cancellation

• The ZNY AC, ZNY DC, ZNY DD, N90 TMDC, or N90 TMAC must notify the STMC, the providing sectors, and affected controllers.
• Controllers must acknowledge with their operating initials.
• The ZNY AC, ZNY DC, ZNY DD, N90 TMDC, or N90 TMAC must send a message containing the cancellation through the ATC Channel or other coordination channel and should cancel the restriction through the NTML as appropriate.
• The STMC will notify any affected neighboring facilities of the cancellation.

Utilized to equitably distribute demand by assigning an aircraft a fix other than the one in the filed flight plan in the departure phase of flight.

Implementation

• The ZNY DD must notify the STMC, the providing sectors, or the N90 TMDC.
  • The ZNY DD (when N90 is not involved) or the N90 TMDC must coordinate fix balancing activities directly with affected Clearance Delivery positions.
  • The ZNY DD or N90 TMDC will either request the affected Towers to equitably distribute demand to different flows as appropriate, or the ZNY PIT positions will assign specific fixes to affected aircraft.
    • When using a shared flight list, identify flights for which a route is unavailable with “NRA” to indicate “no route available”. This will identify to the ZNY PIT positions that the flight is without a valid route.
    • When a pre-coordinated non-event route is available, it is not necessary to coordinate reroutes with ZNY DD or ZNY PIT positions unless specifically requested.

Controllers must acknowledge each directive with his/her operating initials.

• • The ZNY DD and N90 TMDC must monitor and analyze sector volume in their sectors to ensure program efficacy and throughput.
  • The ZNY DD or N90 TMDC should enter any departure stops (STOP) into the NTML.
  • If a conflict cannot be resolved by appropriate officials, the vATCSCC holds final decision-making authority.

Cancellation

• The ZNY DD must notify the STMC, the providing sectors, or the N90 TMDC.
  • Controllers must acknowledge with their operating initials.
• The ZNY DD (when N90 is not involved) or the N90 TMDC must notify affected Clearance Delivery positions and TRACON controllers of the status of the departure gates and should cancel any STOP restrictions through the NTML as appropriate.

Planned aircraft holding may be utilized. This is normally done when the operating environment supports holding and the weather conditions are expected to improve shortly; this ensures aircraft are available to fill the capacity at the airport.

Implementation

• The ZNY AC (when N90 is not involved) or the N90 TMAC must notify the STMC, the providing sectors, and affected controllers to either randomly or selectively hold aircraft.
  • The ZNY AC or the N90 TMAC must specify to the applicable controllers the callsign(s) of the aircraft to be held.
  • The ZNY AC or the N90 TMAC will also provide the appropriate controller with a release time (RTIME) for each aircraft held or an approximate hold time for random aircraft.
  • For blanket hold times, a notification must include the following:
    • average hold time (in minutes) per aircraft; and,
    • approximate duration of holding period.
  • TMU must enter the restriction into the vATCSCC #ntml and, as appropriate, send a message containing the restriction through the ATC Channel.
  • Controllers must acknowledge each directive with his/her operating initials.
• The STMC must notify any affected neighboring facilities of the constraints.

Cancellation

• The ZNY AC or N90 TMAC must notify the STMC, the providing, or affected controllers of the cancellation.
  • Controllers must acknowledge with their operating initials.
• The STMC will notify any affected neighboring facilities of the cancellation.

TEC may be used to relieve upper-level congestion by capping aircraft—preventing them from reaching the enroute stratum by keeping them at lower terminal altitudes—and handing them off from terminal sector to terminal sector instead of center to center.

• The use of non-standard TEC routes during periods of high traffic density is subject to terminal congestion and conforming traffic.
• The use of TEC within N90 requires the notification and approval of Local Control at any of the New York Metro airports and any TRACON sectors traversed.
  • The Local Controller, or the N90 TMDC at the request of the Local Controller, should coordinate with the Controllers at any other traversed facility.
• TEC routes can be found in the NFDC Preferred Routes Database by entering TEC into the Route Type field.

CFR is used when the enroute stream is heavy, restricting the ability of departures from joining the overhead flow or when it is desirable to have individual releases to manage traffic.

Implementation

• The ZNY DC, ZNY DD, or N90 TMDC must notify the STMC and Local Control of the affected facility.

Controllers must acknowledge with their operating initials.

• The ZNY DC, ZNY DD, or N90 TMDC must determine what filters will be selected to apply CFR. Filters include but are not limited to
  • Specific Route
    • e.g., PHL departures via PTW
  • Aircraft Type
    • e.g., All heavy jets
  • Destination
    • e.g., flights arriving MDT
• Once the filters have been selected, the ZNY STMC or N90 STMC will notify all affected facilities that CFR is in place and include
  • anticipated program start time
  • anticipated program end time
  • associated restrictions
  • contact information (e.g., dial number, ATC Channel, Hotline)
  • remarks (optional)
• If an external facility is requested to CFR for flights arriving ZNY or N90, the applicable ZNY AC, ZNY EC, or N90 TMAC will coordinate all CFR implementation.
• The ZNY DC, ZNY AC, N90 TMDC, or N90 TMAC should create an entry in the NTML when CFR is in place.

Cancellation

• The ZNY DC, ZNY DD, ZNY AC, ZNY EC, N90 TMDC, or N90 TMAC must notify the STMC, providing sectors, and affected controllers of the cancellation.
  • Controllers must acknowledge with their operating initials.
• The ZNY DC, ZNY AC, ZNY EC, N90 TMDC, or N90 TMAC should delete the NTML entry containing the CFR advisory.
• The STMC will notify any affected neighboring facilities of the cancellation.
