Local airport advisory as indicated on aeronautical charts.
A service provided by flight service stations or the military at airports not serviced by an operating control tower.

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.
