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 fatali ...

Air Malta Pre Flight Inspection Airbus A320
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

Air Taxi
An air taxi is a small commercial aircraft that makes short flights on demand. In 2001 air taxi operations were promoted in the United States by a NASA and aerospace industry study on the potential Small Aircraft Transportation System (SATS) and the rise of light-jet aircraft manufacturing. Since 2016, air taxis have reemerged as part of the burgeoning field of eVTOL. Regulation In Canada, air taxi operations are regulated by Transport Canada under Canadian Aviation Regulation 703. The Canadian definition of air taxi includes all commercial single-engined aircraft, multi-engined helicopters flown by visual flight rules by one pilot and all multi-engined, non-turbo-jet aircraft, with a maximum take-off weight or less and nine or fewer passenger seats, that are used to transport people or goods or for sightseeing. In the US, air taxi and air charter operations are governed by 14 CFR Part 135 and 14 CFR part 298 of the Federal Aviation Regulations (FAR).

Gyrocopters
An autogyro (from Ancient Greek, Greek and , "self-turning"), also known as a ''gyroplane'', is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift (force), lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down. The autogyro was invented by Spanish engineer Juan de la Cierva in an attempt to create an aircraft that could fly safely at low speeds. He first flew one on 9 January 1923, at Cuatro Vientos Airport, Cuatro Vientos Airfield in Madrid. The aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller. Cierva's autogyro is considered the predecessor of the modern helicopter. The success of the autogyro garnered the interest of industrialists and under license from Cierva in ...

Airmail
Airmail (or air mail) is a mail transport service branded and sold on the basis of at least one leg of its journey being by air. Airmail items typically arrive more quickly than surface mail, and usually cost more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. The Universal Postal Union adopted comprehensive rules for airmail at its 1929 Postal Union Congress in London. Since the official language of the Universal Postal Union is French, airmail items worldwide are often marked ''Par avion'', literally: "by airplane". For about the first half century of its existence, transportation of mail via aircraft was usually categorized and sold as a separate service (airmail) from surface mail. Today it is often the case that mail service is categorized and sold according to transit time alone, with mode of transport (land, sea, air) being decided on ...

Transcontinental Airway System
The Transcontinental Airway System was a navigational aid deployed in the United States during the 1920s. History In 1923, the United States Congress funded a sequential lighted airway along the transcontinental airmail route. The lighted airway was proposed by National Advisory Committee for Aeronautics (NACA), and deployed by the Department of Commerce. It was managed by the Bureau of Standards Aeronautical Branch. The first segment built was between Chicago and Cheyenne, Wyoming. It was situated in the middle of the airmail route to enable aircraft to depart from either coast in the daytime, and reach the lighted airway by nightfall. Lighted emergency airfields were also funded along the route every 15–20 miles. Construction pace was fast, and pilots wishing to become airmail pilots were first exposed to the harsh wintertime work with the crews building the first segments of the lighting system. By the end of the year, the public anticipated anchored lighted airways acr ...

Autopilot
An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"''). The etymology of the nickname is unclear: some claim it is a reference to inventor George De Beeson, who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to King George VI. First autopilots In th ...

Lawrence Sperry
Lawrence Burst Sperry (21 December 1892, Chicago, Illinois, United States – December 13, 1923, English Channel) was an aviation pioneer who invented the autopilot and the artificial horizon. Biography He was the third son of the gyrocompass co-inventor, Elmer Ambrose Sperry, and his wife Zula. Sperry invented the first autopilot, which he demonstrated with startling success in France in 1914. Sperry is also credited with developing the artificial horizon still used on most aircraft in the early 21st century. In 1918 he married film actress Winifred Allen, and ''Flying Magazine'' reported that they were "the first couple to take an aerial honeymoon" after they flew from Amityville to Governors Island. On 13 December 1923 Sperry took off amid fog in a Verville-Sperry M-1 Messenger from the United Kingdom headed for France but never reached his destination. His body was found in the English Channel on 11 January 1924. Legacy A website using the name '' Mile High Club'' ...

Avionics
Avionics (a blend of ''aviation'' and ''electronics'') are the electronic systems used on aircraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at '' Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they were shot down. The first experimental radio trans ...

American Airlines Flight 587
American Airlines Flight 587 was a regularly scheduled international passenger flight from John F. Kennedy International Airport to Las Américas International Airport in Santo Domingo, the capital of the Dominican Republic. On November 12, 2001, the Airbus A300B4-605R flying the route, crashed into the neighborhood of Belle Harbor, on the Rockaway Peninsula of Queens, New York City, shortly after takeoff. All 260 people aboard the plane (251 passengers and 9 crew members) were killed, as well as five people on the ground. It is the second-deadliest aviation accident in U.S. history behind the crash of American Airlines Flight 191 in 1979, and the second-deadliest aviation incident involving an Airbus A300. The location of the accident, and the fact that it took place two months and one day after the September 11 attacks on the World Trade Center in nearby Manhattan, initially spawned fears of another terrorist attack, but the National Transportation Safety Board (NTSB) attri ...

September 11, 2001 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Cen ...

Property Damage
Property damage (or cf. criminal damage in England and Wales) is damage or destruction of real or tangible personal property, caused by negligence, willful destruction, or act of nature. It is similar to vandalism and arson (destroying property with fire), property damage includes vandalizing property that people own, while causing more physical damage and high costs. It can also be a synonym or term under these categories. Sub types of property damage are malicious destruction of property (sometimes called destruction of property or simply destruction) which is towards real property, and damage to property is towards tangible personal property. See also * Criminal mischief *Criminal damage in English law *Arson *Vandalism Vandalism is the action involving deliberate destruction of or damage to public or private property. The term includes property damage, such as graffiti and defacement directed towards any property without permission of the owner. The ter ... ...
