the MIDDS. In a "static" brief, the products are saved and are not updated when new ones are ingested into the MIDDS. A static brief is essentially a snap shot of weather data at a specific point in time. This information can be quite useful during major weather events. The idea is to preserve your data for future reference. MIDDS can also display a brief over a LAN through a web browser with Hypertext Markup Language (HTML). You may create multiple briefs tailored for many users. In addition, the MIDDS weather brief program will enable aviation weather forecasters to provide computerized flight weather briefing forms (DD Form 175-l) while remaining in accordance with NAVMETOCCOMINST 3140.14, Procedures Governing Flight Weather Briefings and Preparing DD Form 175-1 and U.S. Navy Flight Forecast Folder. This program contains the entire DD Form 175-1 and is subdivided into its respective parts (I through IV). The program is designed to automatically ingest TAF and observation data from the AWN and place it on the form (fig. 1-10). All DD-175-1 briefs may be archived to a floppy diskette or another hard drive. Automated Surface Observing System (ASOS) A communications link between MLDDS and the Automated Surface Observing System (ASOS) may be established. The software for this application is divided into two main sections, ASOS Data Server and ASOS Data Manager. The ASOS Data Server is a software program providing ingest and dissemination of 1- minute surface observation data from the ASOS. The other software program is the ASOS Data Manager. This application provides a display of both current and historical ASOS data in an easy-to-use method. The main display consists of a menu bar, two graphs, panes for the latest reported observation, wind speed and direction dials, and a "current status" banner (fig l-l 1). The two graphical displays are "strip charts," which can provide visual analysis of weather phenomena trends, such as temperature and wind speed. As an additional feature, alarms can be set to go off when station Figure 1-10.—Flight weather briefing form (DD Form 175-l) constructed using MIDDS. 1-18
