Aerobatics
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a par ...

Competition Aerobatics
Competition aerobatics is an air sport in which ground-based judges rate the skill of pilots performing aerobatic flying. It is practised in both piston-powered single-engine airplanes and also gliders. An aerobatic competition is sanctioned by a national aero club, its designee, or in the case of international competitions, by CIVA, the Commission Internationale de Voltige Aerienne, which is a constituent body of the Fédération Aéronautique Internationale (FAI). The sanctioning body establishes the rules that apply to the competition, including entry qualifications for all participants, operating procedures, and judging criteria. A pilot enters a competition in a ''category'' of his or her choice, which defines the level of difficulty of the aerobatic sequences to be flown. Within each category, a pilot flies one or more ''flight programs''. Each flight receives a total score from the judges; ranking each pilot's combined total scores for all flight programs within each ...

Aerobatic Manoeuvre
Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics. Aerobatics can be performed by a single aircraft or in formation with several others. Nearly all aircraft are capable of performing aerobatics maneuvers of some kind, although it may not be legal or safe to do so in certain aircraft. Aerobatics consist of five basic maneuvers: * Lines (both horizontal and vertical), * loops, * rolls, * spins, and * hammerheads. Most aerobatic figures are composites of these basic maneuvers with rolls superimposed. A loop is when the pilot pulls the plane up into the vertical, continues around until they are heading back in the same direction, like making a 360 degree turn, except it is in the vertical plane instead of the horizontal. The pilot will be inverted (upside down) at the top of the loop. A loop can also be performed by rolling inverted and making the same maneuver but diving towards the ground. It can b ...

Pitts Special
The Pitts Special (company designations S-1 and S-2) is a series of light aerobatic biplanes designed by Curtis Pitts. It has accumulated many competition wins since its first flight in 1944. The Pitts biplanes dominated world aerobatic competition in the 1960s and 1970s and, even today, remain potent competition aircraft in the lower categories.Montgomery and Foster 1992, p. 92."Plane and Pilot" 1977, p. 84. Design and development Curtis Pitts began the design of a single-seat aerobatic biplane in 1943–1944.Taylor 1980, p. 899. The design has been refined continuously since the prototype first flew in September 1944; however, the current Pitts S-2 still remains quite close to the original in concept and in design. Several of the aircraft that Curtis Pitts built had a picture of a skunk on them and were called "Stinkers". After she bought it, aerobatic performer Betty Skelton called the second aircraft that Curtis built, "Little Stinker". The prototype S-2, wh ...

Spin (flight)
In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a crash may require a specific and counter-intuitive set of actions. A spin differs from a spiral dive, in which neither wing is sta ...

Alpha 2000
The Alpha Aviation Alpha 2000 is a two-seat, all-metal training and general aviation aircraft, designed by Chris Heintz and built in Hamilton, New Zealand. It continues the successful French Apex Aircraft's Robin R2000 series acquired upon Apex's purchase of the Avions Robin company. History 1971–1994 The original Avions Robin HR200 was designed by Christophe Heintz, to supplement the earlier Avions Robin designs of Jean Délémontez who also designed the popular post war wooden Jodel. The HR 200 prototype first flew on 19 July 1971, and entered production in 1973. The R2000 Alpha name was applied to a new aircraft which shared the fuselage of the HR 200, but had all new wing and tail surfaces, to allow aerobatics. The prototype R2000 Alpha flew on 15 January 1976 and production followed in 1977 to 1983. The aircraft features side-by-side seating, an innovative control stick mechanism which reduces the risk of blockage and an unusually large payload for an aerobatic aircraft ...

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

Sukhoi Su-29
The Sukhoi Su-29 is a Russian two-seat aerobatic aircraft with a 268 kW (360 hp) radial engine. It was designed based on the Su-26 and inherited most of the design and technical features of its predecessor. Due to wide use of composite materials, which make up as much as 60% of the Su-29's aircraft structure, the empty weight is increased by only 50 kg (110 lb) over the single-seat Su-26's empty weight. The Su-29 is used for initial pilot aerobatics education, flight training, and participation of pilots in aerobatics competitions and air shows, as well as for maintaining flight skills of military and civil pilots.

Black Cats (Royal Navy)
The Wildcat Demo Team (Black Cats) are the Royal Navy's helicopter display team. The team is composed of two AgustaWestland Wildcat HMA.2 anti-submarine and anti-shipping helicopters, with the aircraft and crews drawn from 825 Naval Air Squadron based at RNAS Yeovilton in Somerset. The team performs at airshows and other public events around the UK and Europe. They perform a display which mixes close formation, opposition and synchronised manoeuvres. History Lynx The Black Cats were formed in 2001 and performed with the Westland Lynx. For their first three display seasons, the team was known as the 'Lynx Pair' – the "Black Cats" title was applied in 2004. The team's predecessors as the Royal Navy Helicopter Display Team were "The Sharks", who used four red Westland Gazelle helicopters and disbanded in 1992. The team won the Steadman Sword for the best British participant at the Royal International Air Tattoo in 2003 and as "Les Chats Noirs" performed at the French N ...

Extra 200
The Extra 200 (Type EA-200) is a two-seat, tandem arrangement, low-wing aerobatic monoplane with conventional ( taildragger) landing gear fully capable of Unlimited category competition, built by Extra Flugzeugbau. Designed by Walter Extra, it was introduced to the United States market in 1996. The Extra 200 is slightly smaller than the Extra 300, and is powered by a 200 hp (149 kW) rather than the Extra 300's 300 hp (224 kW) Lycoming engine making it a great choice for those on a restricted budget. It offers the flying characteristics of the EA-300, is capable of all unlimited maneuvers, and makes a great all-round training/sports aerobatic aircraft. Design The Extra 200 is based on the design of the Extra 300, and the two aircraft share many similarities. The Extra 200 has a welded steel (4130) tube fuselage covered in fiberglass and fabric with a carbon/glass hybrid composite empennage (i.e., the tail assembly, including the horizontal and vertical stab ...

Westland Lynx
The Westland Lynx is a British multi-purpose twin-engined military helicopter designed and built by Westland Helicopters at its factory in Yeovil. Originally intended as a utility craft for both civil and naval usage, military interest led to the development of both battlefield and naval variants. The Lynx went into operational usage in 1977 and was later adopted by the armed forces of over a dozen nations, primarily serving in the battlefield utility, anti-armour, search and rescue and anti-submarine warfare roles. The Lynx is a fully aerobatic helicopter with the ability to perform loops and rolls. In 1986, a specially modified Lynx set the current Fédération Aéronautique Internationale's official airspeed record for helicopters (category excludes compound helicopters) at , which remains unbroken as of January 2022.
