Published by Aviation Supplies & Academics, Inc. 7005 132nd Place SE Newcastle, WA 98059-3153 Preface to the Third Edition There is no aspect of modern technology that encompasses so many disciplines as aviation: physics, chemistry, aerodynamics, thermodynamics, structural and fluid mechanics, electronics, acoustics, reciprocating and turbine engine technology, meteorology, and navigation. In addition, aviation is governed by an extremely complex set of federal regulations. Each discipline and regulation has its own unique vocabulary, and it is difficult to find a single reference source that includes terms specific to the aviation application of these fields. To this end, ASA's editors have searched aviation periodicals, aviation-related textbooks, service manuals, manufacturers’ literature, engineering reports, military training manuals, and especially all of the publications produced by the FAA for applicable terms. This third edition of ASA’s Dictionary of Aeronautical Terms is more than a lexicon; it explains as well as defines more than 7,400 terms and includes some 485 illustrations and four appendices. The names of the Federal Aviation Regulations have been changed from FARs to parts of Title 14 of the Code of Federal Regulations, and in this dictionary, each reference to a federal regulation is identified by the prefix 14 CFR. The officially recognized definitions for many of the aviation terms are included in 14 CFR Part 1 Definitions and Abbreviations. In all instances where a definition in this dictionary is taken directly from this document, it is identified by the prefix 14 CFR Part 1:, and the definition is in quotation marks. The information contained here is as accurate and up-to-date as it has been possible to make it, but because of the speed with which changes are taking place in aviation, some of the terms are taking on new meanings, and their relative importance is changing. Because of this, and because of ASA’s dedication to working together for excellence, we will appreciate any criticism, or suggestion you have that will make Printed from Summit Aviation's Computerized Aviation Reference Library, 2/7/2007 Page 2 subsequent revisions of this work more useful to you. Dale Crane Dictionary A AAM (air-to-air missile). A missile carried on an aircraft for use against other aircraft. The missile is guided to its target by radar or infrared sensors. AAR (airport acceptance rate) (air traffic control). A dynamic input parameter specifying the number of arriving aircraft which an airport or airspace can accept from the ARTCC per hour. The AAR is used to calculate the desired interval between successive arrival aircraft. A & B hydraulic brake system. A form of backup brake system used in some large aircraft multiple-disk power brake installations. Wheels using the A & B system have several small actuating cylinders built into the brake housing. Half of the cylinders are actuated by fluid from the A-hydraulic system and the others by fluid from the B-system. The brakes operate normally with either system. A & P mechanic. A person who holds an aircraft mechanic certificate with both the airframe and powerplant ratings. This certification is issued by the Federal Aviation Administration under the provisions of Federal Aviation Regulations Part 65. Mechanic certification with an A&P rating is scheduled to be replaced by AMT (aviation maintenance technician) certification with an aircraft rating under the proposed 14 CFR Part 66. AAS (airport advisory service). A service provided by FAA Flight Service Stations located at airports not served by a control tower. AAS provides information to arriving and departing aircraft concerning wind direction and speed, favored runway, altimeter setting, pertinent known traffic, pertinent known field conditions, airport taxi routes, traffic patterns, and authorized instrument approach procedures. AAS information is advisory in nature and does not constitute an ATC clearance. www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：航空术语词典Dictionary of Aeronautical Terms 上
