The Sector Design Analysis Tool (SDAT)
What is SDAT ?
The Sector Design Analysis Tool (SDAT) is a computer program designed to assist Air Route Traffic
Control Center (ARTCC) Airspace and Procedures Specialists, and airspace analysts in the design of
airspace. SDAT is intended to provide the airspace designer with a fast, easy, and accurate way to
develop and evaluate proposed changes to airspace structure and/or traffic loading. SDAT is easy to use
and is compatible with many different types of airspace and traffic data.
SDAT Features
SDAT allows one to view airspace structures and features in two and three dimensional (2-D and 3-D)
representations and to rotate the entire display so that it can be viewed from various angles. One can
view specific airspace features including airways, adapted routes, NAVAIDs, fixes, airports, etc.
(i.e., HOST Adaptation data). One can also view flight plans and flight track data from a host of
different sources including HOST System Analysis Recording (SAR) recorded air traffic information,
Enhanced Traffic Management System (ETMS), and Automated Radar Terminal System (ARTS). In addition, one
can modify, add or delete Adaptation and air traffic data.
A newer feature of SDAT is the ability to retrieve and view multiple centers during your current SDAT
session.. This new feature now allows one to perform airspace analyses across center boundaries, giving
you the ability to study the impact of changes made in one center on another center.
SDAT is able to perform various analyses, such as conflict potential, and fix and airspace loading,
using either the original or modified Adaptation data and/or traffic information. Predictions of
conflict potential, traffic and airspace loading, and impacts on the airspace user can be generated for
any proposed combination of airspace and traffic data.
SDAT produces reports describing Adaptation and traffic modifications, and other information of interest
to the user. The Adaptation Modification Report is produced in a format that is compatible with the HOST
Adaptation Controlled Environment System (ACES), thus reducing the work required to re-code and enter
the data.
SDAT also produces reports and graphs summarizing the results of your analyses in a readily usable
format. Reports and graphs generated include traffic, fix, sector, and sketch loading, adaptation and
traffic modifications, conflicts, and impacts of changes, and flights affected.
SDAT Environment
The latest version, SDAT 5.0, is written in C++ and
runs in the Windows environment At the FAA William J. Hughes Technical Center
SDAT 4.0 runs on an SGI O2 Workstation running IRIX 6.5 .
