The ATC Operational Evaluation of the Prototype Integrated Terminal Weather System (ITWS) at Dallas/Fort Worth and Orlando Airports (May-September 1993).

Abstract : The Integrated Terminal Weather System (ITWS) was developed by Massachusetts Institute of Technology/Lincoln Laboratory (MITILL). The ITWS processor acquires data from Federal Aviation Administration (FAA) and National Weather Service (NWS) weather sensors in the terminal area and provides an integrated set of safety and planning weather products to air traffic personnel. An operational evaluation of the ITWS functional prototype was performed from May through September, 1993 at Dallas/Fort Worth (DFW) and Orlando (MCO) airports. ITWS geographical situation displays (6 SD) were located both at DFW and MCO as well as the Fort Worth Air Route Control Center (ARTCCXZFW) and Jacksonville ARTCC (ZJX). The purpose of testing ITWS at these sites was to evaluate various technical and operational issues of IIWS weather products and their display and usability on the GSD. (AN)
