|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|

|61-140A||AFS-800||Autorotation Training The purpose of this advisory circular (AC) is to describe enhanced guidelines for autorotations during helicopter flight training. The Federal Aviation Administration (FAA) has found a need to raise awareness of the risks inherent in performing autorotations in the training environment, and in particular, 180-degree autorotations. In this AC, the FAA recommends procedures that will mitigate safety risk during autorotations. This information is intended to supplement information about autorotation training found in the current editions of the Helicopter Flying Handbook (HFH), FAA-H-8083-21, and the Helicopter Instructor’s Handbook (HIH), FAA-H-8083-4. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, of conducting autorotation training for proficiency or in consideration of the requirements to be issued an Airman Certificate under Title 14 of the Code of Federal Regulations (14 CFR) part 61. You may use alternate methods for training if you establish that those methods meet the requirements of the HFH and FAA practical test standards (PTS).||08-31-2016|
