Chapter 11. Traffic Management Procedures
Section 1. General
11-1-1. DUTY RESPONSIBILITY
a. The mission of
the traffic management system is to
balance air traffic demand with system capacity to
ensure the maximum efficient utilization of the NAS.
b. It is recognized that the ATCS is integral in the
execution of the traffic management mission.
NOTE-
Complete details of traffic management initiatives and
programs can be found in FAAO JO 7210.3, Facility
Operation and Administration.
11-1-2. DUTIES AND RESPONSIBILITIES
a. Supervisory Traffic Management Coordinator-in-Charge (STMCIC) must:
1. Ensure that an operational briefing is
conducted at least once during the day and evening
shifts. Participants must include, at a minimum, the
STMCIC, Operations Supervisors (OS), Traffic
Management Coordinator(s) (TMC), and other
interested personnel as designated by facility
management. Discussions at the meeting should
include meteorological conditions (present and
forecasted), staffing, equipment status, runways in
use, AAR and traffic management initiatives (present
and anticipated).
2. Assume responsibility for TMC duties when
not staffed.
3. Ensure that traffic management initiatives are
carried out by Supervisory Traffic Management
Coordinator-in-Charge (STMCIC).
4. Where authorized, perform URET data
entries to keep the activation status of designated
URET Airspace Configuration Elements current.
5. Perform assigned actions in the event of a
URET outage or degradation, in accordance with the
requirements of FAA Order JO 7210.3, Facility
Operation and Administration, and as designated by
facility directive.
6. Ensure changes to restrictions based on the
Restrictions Inventory and Evaluation are implemented in a timely manner.
b. FLM must:
1. Keep the TMU and affected sectors apprised
of situations or circumstances that may cause
congestion or delays.
2. Coordinate with the TMU and ATCSs to
develop appropriate traffic management initiatives
for sectors and airports in their area of responsibility.
3. Continuously review traffic management
initiatives affecting their area of responsibility and
coordinate with TMU for extensions, revisions, or
cancellations.
4. Ensure that traffic management initiatives are
carried out by ATCSs.
5. Where authorized, perform URET data
entries to keep the activation status of designated
URET Airspace Configuration Elements current.
6. Perform assigned actions in the event of a
URET outage or degradation, in accordance with the
requirements of FAA Order JO 7210.3, Facility
Operation and Administration, and as designated by
facility directive.
7. Ensure changes to restrictions based on the
Restrictions Inventory and Evaluation are implemented in a timely manner.
c. ATCSs must:
1. Ensure that traffic management initiatives
and programs are enforced within their area of
responsibility. Traffic management initiatives and
programs do not have priority over maintaining:
(a) Separation of aircraft.
(b) Procedural integrity of the sector.
2. Keep the OS and TMU apprised of situations
or circumstances that may cause congestion or
delays.
3. Continuously review traffic management
initiatives affecting their area of responsibility and
coordinate with OS and TMU for extensions,
revisions, or cancellations.
4. Where authorized, perform URET data
entries to keep the activation status of designated
URET Airspace Configuration Elements current.
5. Perform assigned actions in the event of a
URET outage or degradation, in accordance with the
requirements of FAA Order JO 7210.3, Facility
Operation and Administration, and as designated by
facility directive.
d. ARTCCs, unless otherwise coordinated, must:
1. Support TMA operations and monitor TMA
equipment to improve situational awareness for a
system approach to traffic management initiatives.
2. Monitor arrival flow for potential metering
actions/changes and, if necessary, initiate
coordination with all facilities to discuss the change
to the metering plan.
e. TRACONs, unless otherwise coordinated,
must:
1. Support TMA operations and monitor TMA
equipment to improve situational awareness for a
system approach to traffic management initiatives.
2. Monitor arrival flow for potential metering
actions/changes and, if necessary, initiate
coordination with all facilities to discuss the change
to the metering plan.
3. Schedule internal departures in accordance
with specific written procedures and agreements
developed with overlying ARTCCs and adjacent
facilities.
f. ATCTs, unless otherwise coordinated, must:
1. Monitor TMA equipment to improve
situational awareness for a system approach to traffic
management initiatives.
2. Release aircraft, when CFR is in effect, so
they are airborne within a window that extends from
2 minutes prior and ends 1 minute after the assigned
time.
NOTE-
Coordination may be verbal, electronic, or written.
11-1-3. TIME BASED FLOW
MANAGEMENT (TBFM)
During periods of metering, ATCS must:
a. Display TMA schedule information on the main
display monitor (MDM).
b. Comply with TMAgenerated metering times
within +/ 1 minute.
1. If TMAgenerated metering time accuracy
within +/ 1 minute cannot be used for specific
aircraft due to significant jumps in the delay
countdown timer (DCT), other traffic management
initiatives may be used between those aircraft such as
milesintrail (MIT) or minutesintrail (MINIT) to
assist in delay absorption until stability resumes.
2. An exception to the requirement to comply
within +/ 1 minute may be authorized for certain
ARTCC sectors if explicitly defined in an appropriate
facility directive.
c. When compliance is not possible, coordinate
with FLM and adjacent facilities/sectors as
appropriate.
NOTE-
TMA accuracy of generated metering times is predicated
on several factors, including vectoring outside of TMA
route conformance boundaries (route recovery logic),
certain trajectory ground speed calculations, and when
TMU resequences a specific flight or flight list. Caution
should be used in these situations to minimize impact on
surrounding sector traffic and complexity levels, flight
efficiencies, and user preferences.
