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.

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 ...

Touch-and-go Landing
In aviation, a touch-and-go landing (TGL) or circuit is a maneuver that is common when learning to fly a fixed-wing aircraft. It involves landing on a runway and taking off again without coming to a full stop. Usually the pilot then circles the airport in a defined pattern known as a circuit and repeats the maneuver. This allows many landings to be practiced in a short time. If the pilot brings the aircraft to a full stop before taking off again, it is known as a "stop-and-go". If the aircraft's wheels do not touch the ground, it is known as a "low pass". Both a touch-and-go landing and a low pass are types of go-around. An unplanned touch-and-go landing is also called a "rejected landing" or "balked landing". Touch-and-go landings can perform a crucial safety role when a plane lands with not enough space to come to a complete stop, but has enough space to accelerate and take off again. Standard procedure In a normal landing, the pilot flies the traffic pattern and establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missed Approach
Missed approach is a procedure followed by a pilot when an instrument approach cannot be completed to a full-stop landing. The instructions for the missed approach may be assigned by air traffic control (ATC) prior to the clearance for the approach. If ATC has not issued specific instructions prior to the approach and a missed approach is executed, the pilot must follow the (default) missed approach procedure specified for the approach. Prior to commencing the approach, pilots can make a specific request to ATC if a missed approach may occur. Such a request may include heading and altitude instructions to avoid in-flight delays (such as holds) and efficiently maneuver the aircraft into position for either its next approach or a diversion to an alternate airport. Generally, if a pilot determines by the time the aircraft is at the decision height (for a precision approach) or missed approach point (for a non-precision approach), that the runway or its environment is not in sight, or ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the "private transport" and recreational components of aviation. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial advertisement. However, for statistical purposes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Control Tower
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advis ...

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

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 ...
