local airport advisory (LAA)
A service provided by flight service stations or the military at airports not serviced by an operating control tower. This service consists of providing information to arriving and departing aircraft concerning the wind direction and speed, favored runway, altimeter setting, pertinent known traffic, pertinent field conditions, airport taxi routes and traffic patterns, and authorized instrument approach procedures. This information is advisory in nature and does not constitute an ATC (air traffic control) clearance. The availability of this service is indicated by the letters LAA on en route charts as indicated in the illustration.
