|00-25||AFS-400||Forming and Operating a Flying Club This Advisory Circular was compiled by the Aviation Education Staff of the Office of General Aviation Affairs, Federal Aviation Administration, Washington, D.C., to provide preliminary information to "flight-minded" men and women who wish to form and operate a flying club. This publication serves to assist anyone or any group of people who are interested in forming and operating a flying club. We recognize there are many other successful approaches for establishing flying clubs.||05-01-1969|
This advisory circular (AC) describes the hazards of thunderstorms to aviation and offers guidance to help prevent accidents caused by thunderstorms.
|00-6B||AFS-400||Aviation Weather This advisory circular (AC) was published by the Federal Aviation Administration (FAA) Flight Standards Service (AFS), with contributions from the National Weather Service (NWS). The publication began in 1943 as CAA Bulletin No. 25, Meteorology for Pilots, which at the time contained weather knowledge considered essential for most pilots. As aircraft flew farther, faster, and higher, and as meteorological knowledge grew, the bulletin became obsolete. It was revised in 1954 under a new title, The Pilots’ Weather Handbook, and updated again in 1965. In 1975 it was revised under its current title.||08-23-2016|
Public Aircraft Operations
This advisory circular (AC) provides information to assist in determining whether government or government-contracted aircraft operations conducted within the territory of the United States are public or civil aircraft operations under the statutory definition of "public aircraft," in Title 49 of the United States Code (49 U.S.C.) §§ 40102(a)(41) and 40125 (the statute). Additionally, this AC contains Federal Aviation Administration (FAA) policy pertaining to civil aircraft operators that provide contract support to government entities. The intent of this material is to better define the responsibilities of the parties to these contracts. This AC is not mandatory and does not constitute a regulation. Nothing in this AC changes the legal requirement for public aircraft operators to comply with the statute.
