Bolter (aviation)
In naval aviation, a bolter occurs when an aircraft attempting an arrested landing on the flight deck of an aircraft carrier touches down, but fails to catch an arrestor cable and come to a stop. Bolter aircraft accelerate at full throttle and become airborne in order to go-around and re-attempt the landing. Prior to the development of the angled flight deck, aircraft carrier landing areas ran along the axis of the ship. If an aircraft failed to catch an arrestor cable on the aft (rear) of the ship, it would still need to be stopped prior to hitting aircraft spotted (parked or taxiing) on the forward half of the deck. With aircraft spotted on the forward half of the flight deck, there was not enough room for an aircraft to become airborne again after missing the arrestor wires. Stopping an aircraft that failed to engage an arrestor cable was accomplished with either a wire barrier rigged amidships and raised to catch the aircraft's landing gear, or a net barricade that would e ...

Arresting Gear
An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems which use nets to catch aircraft wings or landing gear. These ''barricade'' and ''barrier'' systems are only used for emergency arrestments for aircraft without operable tailhooks. History Arresting cable systems were invented by Hugh Robinson and were utilized by Eugene Ely on his first land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailhook
A tailhook, arresting hook, or arrester hook is a device attached to the empennage (rear) of some military fixed-wing aircraft. The hook is used to achieve rapid deceleration during routine landings aboard aircraft carrier flight decks at sea, or during emergency landings or aborted takeoffs at properly equipped airports. The tailhook was first demonstrated at sea on 18 January 1911 by the aviator Eugene Ely, having successfully landed aboard the armored cruiser USS ''Pennsylvania'' with the aid of the device. It was not until the early 1920s that a practical system, paired with deck-mounted arresting gear, was devised and put into use. During the 1930s, numerous vessels were thus equipped, permitting the use of increasingly heavy combat aircraft at sea during the Second World War. Following the introduction of jet-powered aircraft during the 1950s, arrestor technology was further advanced to permit aircraft operating at greater speeds and weights to land aboard aircraft car ...

Modern US Navy Carrier Air Operations
Modern United States Navy aircraft carrier air operations include the operation of fixed-wing and rotary aircraft on and around an aircraft carrier for performance of combat or noncombat missions. The flight operations are highly evolved, based on experiences dating back to 1922 with . Flight deck crew On an aircraft carrier flight deck, specialized crew are employed for the different roles utilized in managing air operations. The different flight deck crews wear colored jerseys to visually distinguish their functions. Everyone associated with the flight deck has a specific job, which is indicated by the color of his deck jersey, float coat and helmet. Rank is also denoted by the pattern of pants worn by flight deck crew: *Navy blue pants – Denotes junior sailors and petty officers. *Khaki pants – Denotes Chief petty officer, chief petty, Warrant officer, warrant and commissioned officers. This keeps in line with the traditional khaki color of CPO and officer servic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landing Signal Officer
A landing signal officer or landing safety officer (LSO), also informally known as paddles (United States Navy) or batsman (Royal Navy), is a naval aviator specially trained to facilitate the "safe and expeditious recovery" of naval aircraft aboard aircraft carriers. LSOs aboard smaller air capable ships that launch and recover helicopters are informally known as deck. Originally LSOs were responsible for bringing aircraft aboard ship using hand-operated signals. Since the introduction of optical landing systems in the 1950s, LSOs assist pilots by giving information via radio handsets. History In the United States Navy, aircraft carrier operations began with USS ''Langley'' (CV-1) in 1922, and it served as a platform to experiment and develop aircraft launch and recovery procedures.Tate, Jackson R., RADM USN "We Rode the Covered Wagon" ''United States Naval Institute Proceedings'' October 1978 p.66-68 The first pilots had no signaling system for assistance from shipboard pe ...

Jet Aircraft
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound. Jet aircraft generally cruise most efficiently at about Mach 0.8 () and at altitudes around or more. The idea of the jet engine was not new, but the technical problems involved could not begin to be solved until the 1930s. Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight. A wide range of different types of jet aircraft exist, both for civilian and military purposes. History After the first instance of powered f ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Angled Flight Deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese Akagi and battleship Kaga, were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner . The armoured flight deck was another innovation pioneered by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Go-around
In aviation, a go-around is an aborted landing of an aircraft that is on final approach or has already touched down. A go-around can either be initiated by the pilot flying or requested by air traffic control for various reasons, such as an unstabilized approach or an obstruction on the runway. Etymology The term arises from the traditional use of traffic patterns at airfields. A landing aircraft will first join the traffic pattern/circuit and prepare for landing. If for some reason, the pilot decides not to land, the pilot can simply fly back up to traffic pattern altitude/circuit height, and complete another circuit. The term "go-around" is still used even for modern airliners, though they may not use traditional traffic patterns/circuits for landing. Reasons for use Initiation of a go-around may be either ordered by air traffic control (normally the local or tower controller in a controlled field) or initiated by the pilot in command of the aircraft.
