Abstract
A method and apparatus for automatically providing advisories to pilots in a monitored airspace comprises monitoring weather conditions and air traffic in an airspace and then generating and broadcasting advisories over a radio channel in response to relevant air traffic conditions. Advisory lengths are sized based on the volume of communications on the common traffic advisory frequency. An airspace model, made up of a multitude of constantly updated records, is used to keep track of important flight information and weather conditions. A monitoring CPU, accessing the airspace model, creates the advisory messages based upon hazard criteria, guidelines, airport procedures and other relevant air traffic data.
