
Sector Traffic Control (R-Side) is responsible
for managing aircraft through the use of
radar.
◦ 5 Minute Timescale

Sector Traffic Planning (D-Side) is responsible
for coordinating handoffs with surrounding
sectors.
◦ 5 – 20 Minute Timescale


Traffic Management Unit handles flight
coordination on a regional scale (centers).
◦ 30 Minutes to 2 Hour Timescale

May impose flow restrictions on aircraft
entering or already in a center if
overcrowding becomes an issue.
◦ Can implement “Miles in Trail” or “Time in Trail”
requirements.

Central Flow Management Unit takes control if
overcrowding becomes too much to handle on
the regional level.
Project traffic loads based on airline schedules
and flight plans.
Pays special attention to weather patterns that
can block routes and close airports.
Utilizes three strategies for overcrowding and
weather.
◦ Ground Holding: Delays takeoff times for aircraft
heading to crowded destination.
◦ Rerouting: Used to maneuver aircraft around weather
systems or overcrowded sectors.
◦ Metering: Method used to manage flow rates into
sectors.

Airlines utilize an Airline Operations Center
for planning company flights.
Centers are staffed by certified flight
dispatchers.
Generate flight plans based on aircraft type,
weight, and loads, weather conditions airport
limitations.
The flight plan details the flight route,
weather, alternative airports, fuel
requirements, and take-off loads.
