<p>In order to ensure the successful demonstration that the Weather Message switching center Replacement (WMSCR) of the Federal Aviation Administration (FAA) can complete its primary mission of accepting and distributing various data formats in use today and those of future systems, including the expected message traffic, this study was initiated.</p> <p> This Test Data set Formulation will specify the various data formats, worst-case traffic load/size, and a distribution scenario for the WMSCR. From this Formulation, an actual Test Data Set can be constructed and used to test the WMSCR.</p> <p> A description of the WMSCR, its operational environment, current users, future users, various message formats and associated sizing requirements per interface are detailed within.</p> / Master of Engineering
