Overview |
The User Request Evaluation Tool (URET) was developed
by MITRE's Center for Advanced Aviation System Development
(CAASD) to assist air traffic controllers with timely
detection and resolution of predicted problems. By
helping to manage workload and allowing more strategic
planning, URET helps the system support a greater
number of user-preferred flight profiles, increased
user flexibility, and increased system capacity, while
maintaining safety levels.
URET processes real-time flight plan and track data
with site adaptation, aircraft performance characteristics,
and temperature and wind data to build four-dimensional
flight profiles, or trajectories, for all flights
within a facility or inbound. When a conflict (i.e.,
possible loss of separation) is detected, URET determines
which sector to notify and displays an alert to that
sector up to 20 minutes prior to the conflict. This
longer look-ahead gives controllers more time for
strategic planning.
In addition to conflict detection capabilities, URET
has introduced a new controller interface that supports
flight data management and task prioritization at
the sector, using both textual and graphic displays.
