In-flight Breakup
An in-flight breakup is a catastrophic failure of an aircraft structure that causes it to break apart in mid-air. This can result in the death of all occupants and the destruction of the aircraft. In-flight breakups are rare but devastating events that can be caused by various factors. Faults in the design or manufacturing of the aircraft can create weak points or stress concentrations in the structure. Constant use and repeated loading and unloading cycles on the aircraft can lead to fatigue (material), fatigue cracking. Additionally, pilot error or adverse weather conditions can cause the aircraft to experience more extreme conditions than those it was designed to tolerate. In some cases, terrorism, sabotage or terrorism can damage critical systems or components, leading to catastrophic failure. Notable in-flight breakups * BOAC Flight 783, BOAC Flight 781 and South African Airways Flight 201 (1953-1954): Flight 783, 781 and Flight 201 were de Havilland Comet, de Havilland Co ...

RAF Phonetic Alphabet
The Allied military phonetic spelling alphabets prescribed the words that are used to represent each letter of the alphabet, when spelling other words out loud, letter-by-letter, and how the spelling words should be pronounced for use by the Allies of World War II. They are not a "phonetic alphabet" in the sense in which that term is used in phonetics, i.e. they are not a system for transcribing speech sounds. The Allied militaries – primarily the US and the UK – had their own radiotelephone spelling alphabets which had origins back to World War I and had evolved separately in the different services in the two countries. For communication between the different countries and different services specific alphabets were mandated. The last WWII spelling alphabet continued to be used through the Korean War, being replaced in 1956 as a result of both countries adopting the ICAO/ITU Radiotelephony Spelling Alphabet, with the NATO members calling their usage the "NATO Phonetic Alpha ...

Airspeed Ambassador
The Airspeed AS.57 Ambassador is a British twin piston-engined airliner that was designed and produced by the British aircraft manufacturer Airspeed Ltd. It was one of the first postwar airliners to be produced. The Ambassador was developed in response to a requirement identified by the Brabazon Committee for a twin-engined short-to-medium-haul airliner as a replacement for the ubiquitous Douglas DC-3. Airspeed assembled a dispersed design team at Fairmile Manor, Cobham, Surrey, in 1943, which initially worked on a smaller proposal powered by Bristol Hercules radial engines; this was quickly superseded by a larger-capacity design aimed at better fulfilling the expansion in postwar civil air travel, although several entities doubted Airspeed's projected growth in air travel. Fitted with the new but conventional Bristol Centaurus radial engines, the Ambassador was designed to accommodate four Napier Nomad turbo-compound engines, a then-recent innovation. Its fuselage was compatib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs. While heavier fixed-wing aircraft such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Certificate Of Airworthiness
A standard certificate of airworthiness is a permit for commercial passenger or cargo operation, issued for an aircraft by the civil aviation authority in the state/nation in which the aircraft is registered. For other aircraft such as crop-sprayers, a Special Airworthiness Certificate (not for commercial passenger or cargo operations) must be issued. Legal authority A certificate of airworthiness (CoA), or an airworthiness certificate, is issued for an aircraft by the civil aviation authority in the state in which the aircraft is registered. The CoA attests that the aircraft is airworthy insofar as the aircraft conforms to its type design. Each certificate is issued in one of a number of different categories when the aircraft is registered in the name of the owner. Thereafter, a yearly currency fee is payable to renew the CoA. If this fee is not paid when due, the certificate expires and the owner must apply again for the certificate. The CoA can only be issued when a mainte ...

Estimated Time Of Arrival
The estimated time of arrival (ETA) is the time when a ship, vehicle, aircraft, cargo, person, or emergency service is expected to arrive at a certain place. Overview One of the more common uses of the phrase is in public transportation where the movements of trains, buses, airplanes and the like can be used to generate estimated times of arrival depending on either a static timetable or through measurements on traffic intensity. In this respect, the phrase or its abbreviation is often paired with its complement, estimated time of departure (ETD), to indicate the expected start time of a particular journey. This information is often conveyed to a passenger information system as part of the core functionality of intelligent transportation systems. For example, a certain flight may have a calculated ETA based on the speed by which it has covered the distance traveled so far. The remaining distance is divided by the speed previously measured to roughly estimate the arrival time. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Frequency
High frequency (HF) is the ITU designation for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters). Frequencies immediately below HF are denoted '' medium frequency'' (MF), while the next band of higher frequencies is known as the '' very high frequency'' (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called ''shortwave radio''. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or "skywave" propagation – these frequencies can be used for long-distance communication across intercontinental distances and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations (3.95–25.8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponza
Ponza (Italian: ''isola di Ponza'' ) is the largest island of the Italy, Italian Pontine Islands archipelago, located south of Cape Circeo in the Tyrrhenian Sea. It is also the name of the commune of the island, a part of the province of Latina in the Lazio region. History The island was inhabited from neolithic through Ancient Rome, Roman times. According to local legends, Ponza was named after Pontius Pilate, Roman governor of Judea who tried Jesus of Nazareth for sedition against Roman rule. Pontius Pilate's family owned a grotto on Ponza, which is still named after him. The Pontius Pilate legend of Ponza's name has recently come into dispute amongst historians, because the name "Pontia" appears in Strabo's ''Geography''. This pre-dates the birth of Pilate. It is not known if this is the same name as Ponza or a similar name. Also, ''Pontia'' means "Land of Bridges" in Latin, a name which could have been applied for Ponza's many naturally occurring arches and bridge-like lan ...
