ABSTRACT
Rerouting flights around severe weather or congestion is an important
Traffic Flow Management (TFM) strategy. The Federal Aviation Administration
(FAA) has been researching ways to improve reroute planning and execution.
The purpose of the work documented in this paper is to refine existing
reroute planning and execution concepts to more fully address Air Route
Traffic Control Center (ARTCC)-initiated rerouting or local rerouting.
Local reroutes are performed primarily in instances when the weather
is affecting departure routes from an airport in the ARTCC. Initial
analysis has shown that the workload involved in local rerouting can
be significant. This paper describes a proposal for improvements to
the current operations. Central to the concept is an interactive capability
available at the Traffic Management Unit (TMU) that presents the traffic
manager with a selectable list of flight-specific reroutes, including
those submitted by National Airspace System (NAS) users. This capability
also allows the traffic manager to understand the effect of each reroute,
to submit the reroute amendment to En Route automation, and to revert
to the original route if the reroute is no longer needed.
