We Have Long Had Weather In- formation available from the FAA and National Weather Service. But there has also been a demand for custom weather services, and these have developed for aviation interests as well as TV and radio stations and others with a vested interest in Mother Nature's tantrums. Interest in this reaches a peak in general aviation with the introduction of weather in the cockpit. The up or downlink of weather information, including the Nexrad mosaic, comes from private services. We pay for virtually all of it, so it is a competitive business. The exception to paying comes with part of the Bendix/King system. The metars, TAFs and pilot reports are available free there because of an FAA contract.
