An MIS is issued by which organization?

The correct answer is that an MIS, or Meteorological Impact Statement, is issued by the CWSU, which stands for Center Weather Service Unit. The CWSU is a specialized branch of the National Weather Service that provides critical weather information to FAA air traffic control facilities and aviation operations.

The MIS is specifically designed to convey significant weather information that may impact air traffic operations. It is particularly useful for pilots and air traffic controllers, as it provides concise information about potential weather hazards, allowing for better route planning and safety management.

While the FAA plays a crucial role in managing air traffic and ensuring safety in aviation, it does not issue weather-specific statements like the MIS. The National Weather Service is the broader agency responsible for meteorological data and forecasts but is not the direct issuer of the MIS. Air Traffic Control focuses on managing aircraft movements and does not generate analytical weather statements. Therefore, the CWSU, being the specific unit responsible for this data in the context of aviation, is the correct entity that issues the MIS.
