Airport Information Look-up, www.AirNav.com. Want to find out who manages an airport, for example, a private airport areas that you have a flight mission? Use this to find contact information for notification purposes (except for air traffic controlled airports, which require a waiver). AirNav website information can sort by State, public and private airports. Very close to the FAA Chart Supplements (formerly the Airport Facility Directory, a.k.a. the Green Book) but not FAA material.
