Advisory Circular
__NOTOC__ Advisory circular (AC) refers to a type of publication offered by the Federal Aviation Administration (FAA) to provide guidance for compliance with airworthiness regulations, pilot certification, operational standards, training standards, and any other rules within the 14 CFR Aeronautics and Space Title. They define acceptable means, but not the only means, of accomplishing or showing compliance with airworthiness regulations. Generally informative in nature, Advisory Circulars are neither binding nor regulatory; yet some have the effect of ''de facto'' standards or regulations. Advisory circulars typically refer to industry standards from SAE (ARP) and RTCA (DO). With harmonization of technical content and guidance between EASA and the FAA, later advisory circulars also identify corresponding EUROCAE (ED) publications. Some advisory circulars are only a few pages long and do little more than reference a recommended standard; for example, AC 20-152 referencing DO- ...

Federal Aviation Administration
The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrounding international waters. Its powers include air traffic management, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. Created in , the FAA replaced the former Civil Aeronautics Administration (CAA) and later became an agency within the U.S. Department of Transportation. Major functions The FAA's roles include: *Regulating U.S. commercial space transportation *Regulating air navigation facilities' geometric and flight inspection standards *Encouraging and developing civil aeronautics, including new aviation technology *Issuing, suspending, or revoking ...

DO-160
DO-160, Environmental Conditions and Test Procedures for Airborne Equipment is a standard for the environmental testing of avionics hardware. It is published by the Radio Technical Commission for Aeronautics (RTCA) and supersedes DO-138. Outline of contents Introduction The DO-160 document was first published on February 28, 1975 to specify test conditions for the design of avionics electronic hardware in airborne systems. Since then the standard has undergone subsequent revisions up through Revision G. Purpose This document outlines a set of minimal standard environmental test conditions (categories) and corresponding test procedures for airborne equipment for the entire spectrum of aircraft from light general aviation aircraft and helicopters through the jumbo jets and supersonic transport categories of aircraft. The purpose of these tests is to provide a controlled (laboratory) means of assuring the performance characteristics of airborne equipment in environmental conditions ...

Regulation Of UAVs In The United States
The US Federal Aviation Administration has adopted the name ''unmanned aircraft'' (UA) to describe aircraft systems without a flight crew on board. More common names include ''UAV'', ''drone'', ''remotely piloted vehicle'' (''RPV''), ''remotely piloted aircraft'' (''RPA''), and ''remotely operated aircraft'' (''ROA''). These "limited-size" (as defined by the '' Fédération Aéronautique Internationale'') unmanned aircraft flown in the USA's National Airspace System, flown solely for recreation and sport purposes, such as models, are generally flown under the voluntary safety standards of the Academy of Model Aeronautics, the United States' national aeromodeling organization. To operate a UA for non-recreational purposes in the United States, according to the FAA users must obtain a ''Certificate of Authorization'' (COA) to operate in national airspace. In December 2015 the FAA announced that all UAVs weighing more than 250 grams flown for any purpose must be registered with the ...

AC 91-57
AC 91–57() is an FAA Advisory Circular (AC) (Subject: ''Exception for Limited Recreational Operations of Unmanned Aircraft'' ) that provides interim safety guidance to individuals operating unmanned aircraft, commonly known as drones, but inclusive of flying model aircraft, for recreational purposes in the National Airspace System of the United States. Summary In 1981, in recognition of the safety issues raised by the recreational operation of RC model aircraft, the FAA published this brief AC, then entitled ''Model Aircraft Operating Standards'', for the purpose of providing guidance to persons interested in flying drones and model aircraft as a hobby or for recreational use. This guidance conveys FAA expectation of good judgment on the part of unmanned aircraft operators so that persons on the ground or other aircraft in flight will not be endangered. The AC contains among other things, guidance for site selection. Users are advised to avoid noise sensitive areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasers And Aviation Safety
Under certain conditions, laser light or other bright lights (spotlights, searchlights) directed at aircraft can be a hazard. The most likely scenario is when a bright visible laser light causes distraction or temporary flash blindness to a pilot, during a critical phase of flight such as landing or takeoff. It is far less likely, though still possible, that a visible or invisible beam could cause permanent harm to a pilot's eyes. Although laser weapons are under development by armed forces, these are so specialized, expensive and controlled that it is improbable for non-military lasers to cause structural damage to an aircraft. Pointing a laser at an aircraft can be hazardous to pilots, and has resulted in arrests, trials and jail sentences. It also results in calls to license or ban laser pointers. Some jurisdictions such as New South Wales, Australia have restricted laser pointers as a result of multiple incidents. Lasers and bright lights In addition to lasers, other brigh ...

ARP4761
ARP4761, Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment is an Aerospace Recommended Practice from SAE International. In conjunction with ARP4754, ARP4761 is used to demonstrate compliance with 14 CFR 25.1309 in the U.S. Federal Aviation Administration (FAA) airworthiness regulations for transport category aircraft, and also harmonized international airworthiness regulations such as European Aviation Safety Agency (EASA) CS–25.1309. This Recommended Practice defines a process for using common modeling techniques to assess the safety of a system being put together. The first 30 pages of the document covers that process. The next 140 pages give an overview of the modeling techniques and how they should be applied. The last 160 pages give an example of the process in action. Some of the methods covered: * Functional Hazard Assessment (FHA) *Preliminary System Safety Assessment (PSSA) *System Safety Assessme ...

ARP4754
ARP4754, Aerospace Recommended Practice (ARP) ARP4754A (''Guidelines For Development Of Civil Aircraft and Systems''), is a guideline from SAE International, dealing with the development processes which support certification of Aircraft systems, addressing "the complete aircraft development cycle, from systems requirements through systems verification." Revision A was released in December 2010. It was recognized by the FAA in AC 20-174 published November 2011. EUROCAE jointly issues the document as ED–79. Objectives of the document The Aerospace Recommended Practice (ARP) is a guideline for development of civil aircraft and systems with an emphasis on safety aspects. Revision A is a substantial rewrite of the document which describes the safety process as a part of an Integrated Development Process. A significant new section is devoted to the process of determining Development Assurance Level (DAL) which determines the rigor of complex hardware and software development and ve ...
