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] |
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 ...

Aviation Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulation and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution In 1926 and 1927, there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929 (killing 61 people), which remains the worst year on record at an accident rate of about 1 for every flown. Based on the current numbers flying, this would equate to 7,000 fatal incidents per year. For the ten-year period 2002 to 2011, 0.6 fatal accidents happened per one million flights globally, 0.4 per million hours flown, 22.0 fatal ...

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 ...

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- ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Model Aircraft
A model aircraft is a small unmanned aircraft. Many are replicas of real aircraft. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models. Aircraft manufacturers and researchers make wind tunnel models for testing aerodynamic properties, for basic research, or for the development of new designs. Sometimes only part of the aircraft is modelled. Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many are available in kits, typically made of injection-moulded polystyrene or resin. Flying models range from simple toy gliders made of sheets of paper, balsa, card stock or foam polystyrene to powered scale models built up from balsa, bamboo sticks, plastic, (including both moulded or sheet polystyrene, and styrofoam), metal, synthetic resin, either alone or with carbon fibr ...

National Airspace System
The National Airspace System (NAS) is the airspace, navigation facilities and airports of the United States along with their associated information, services, rules, regulations, policies, procedures, personnel and equipment. It includes components shared jointly with the military. It is one of the most complex aviation systems in the world, and services air travel in the United States and over large portions of the world's oceans. Organization A flight through the NAS typically begins and ends at an airport which may be controlled (by a tower) or uncontrolled. On departure, the aircraft is in one of five of the six classes of airspace administered by the Federal Aviation Administration (FAA), and different flight rules apply to each class. Depending on the class of airspace and flight conditions, communication with controllers may or may not be required. Operation of each flight is always the responsibility of the pilot in command, but air traffic controllers give instructions fo ...

Radio-controlled Aircraft
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is controlled remotely by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver (radio), receiver within the craft that sends signals to servomechanisms (servos) which move the Flight control surfaces, control surfaces based on the position of joysticks on the transmitter. The control surfaces, in turn, directly affect the orientation of the plane. Flying RC aircraft as a hobby grew substantially from the 2000s with improvements in the cost, weight, performance, and capabilities of motors, battery (electricity), batteries and electronics. Scientific, government, and military organizations are also using RC aircraft for experiments, gathering weather readings, aerodynamics, aerodynamic modeling, and testing. A wide variety of models, parts, and styles is available for the DIY market. Nowadays, distinct from recreationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Title 49 Of The United States Code
Title 49 of the United States Code is a positive law title of the United States Code with the heading "Transportation." The title was enacted into positive law by , § 1, October 17, 1978, ; , § 1, January 12, 1983, ; and , July 5, 1994, (subtitles II, III, and V-X) During the time between when the Title 49 positive law codification began in 1978 and when it was completed in 1994, the remaining non-positive law sections were placed in an appendix to Title 49. In 1995, the ICC Termination Act, substantively and significantly amended Title 49. In 2010, Congress enacted Title 51 as a new positive law title concerning NASA and commercial space programs. As part of the codification, the heading of Subtitle IX was marked "transferred" and the contents of such subtitle were moved to Title 51. Five years later, the FAST Act inserted a new Subtitle IX. The heading of new Subtitle IX was given the heading "Multimodal Freight Transportation."Fixing America's Surface Transportatio ...

Regulation Of Unmanned Aerial Vehicles
The use of unmanned aerial vehicles (UAVs) or Drones, is generally regulated by the civil aviation authority of the country. Nevertheless, the International Civil Aviation Organization (ICAO) began exploring the use of drone technology as far back as 2005, which resulted in a 2011 report. France was among the first countries to set a national framework based on this report and larger aviation bodies such as the FAA and the EASA quickly followed suit, which eventually led to influential regulations such aPart 107anRegulation (EU) 2019/947 As of January 2022, several countries are working on new regulations, ranging from BVLOS (beyond visual line of sight, or BLOS) operations to UTM (unmanned traffic management) activities, which include the US, the EU, India, South Korea, Japan, and Australia among others. Certification aspects One of the main barriers to rapid full-scale growth of commercial unmanned aircraft is the concern for safety. As myriad certification agencies scramble to ...
