22-649: The Red Checkers was the aerobatic /precision flying Team of the Royal New Zealand Air Force . The Checkers fly the Pacific Aerospace CT-4E Airtrainer . Previous aircraft used were the CT4B and North American Harvard (T-6). Until the year 1994 the Checkers were based at Wigram . Aircraft used by the team had a nose painted in a red and white checkered pattern, but this has now been reduced to

44-456: A flux of so many gamma ray , x-ray , ultraviolet , visual light and heat photons strikes matter in a such brief amount of time (a great number of high-energy photons, many overlapping in the same physical space) that all molecules lose their atomic bonds and "fly apart". All atoms lose their electron shells and become positively charged ions, in turn emitting photons of a slightly lower energy than they had absorbed. All such matter becomes

66-456: A flying circus to entertain. Maneuvers were flown for artistic reasons or to draw gasps from onlookers. In due course some of these maneuvers were found to allow aircraft to gain tactical advantage during aerial combat or dogfights between fighter aircraft. Aerobatic aircraft fall into two categories—specialist aerobatic, and aerobatic capable. Specialist designs such as the Pitts Special ,

88-470: A gas of nuclei and electrons which rise into the air due to the extremely high temperature or bond to each other as they cool. The matter vaporized this way is immediately a plasma in a state of maximum entropy and this state steadily reduces via the factor of passing time due to natural processes in the biosphere and the effects of physics at normal temperatures and pressures . A similar process occurs during ultrashort pulse laser ablation , where

110-482: A small checkered stripe. In 1973 the team was disbanded due to a world fuel crisis but was formed again in 1980. Squadron Leader Nick Cree was killed when the CT-4 training aircraft he was flying hit the ground while practicing aerial display manoeuvres near RNZAF Base Ohakea on 14 January 2010. On 1 March 2010 two aircraft touched during training with one aircraft incurring minor damage. The Red Checkers were grounded for

132-466: A solution will eventually leave behind a cryogenic liquid. Boiling is also a phase transition from the liquid phase to gas phase, but boiling is the formation of vapor as bubbles of vapor below the surface of the liquid. Boiling occurs when the equilibrium vapor pressure of the substance is greater than or equal to the atmospheric pressure . The temperature at which boiling occurs is the boiling temperature, or boiling point. The boiling point varies with

154-419: Is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs on the surface . Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure . For example, due to constantly decreasing pressures, vapor pumped out of

176-524: Is a portmanteau of "aeroplane" 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

198-466: Is due to the ability to limit blood pooling for positive g maneuvers, but it is generally accepted that +9 g for more than a few seconds will lead to loss of consciousness (also known as GLOC ). Aerobatics are most likely to be seen at public airshows in the form of stunt flying. Aerobatic competitions usually do not attract large crowds of spectators since the manoeuvers are flown at safe altitudes to avoid accidents. Vaporization Evaporation

220-836: The Extra 200 and 300 , and the Sukhoi Su-26 M and Sukhoi Su-29 aim for ultimate aerobatic performance. This comes at the expense of general purpose use such as touring, or ease of non aerobatic handling such as landing. At a more basic level, aerobatic capable aircraft, such as the Cessna 152 Aerobat or the R2160 Acrobin , can be dual purpose—equipped to carrying passengers and luggage, as well as being capable of basic aerobatic figures. Flight formation aerobatics are flown by teams of up to sixteen aircraft, although most teams fly between four and ten aircraft. Some are state funded to reflect pride in

242-634: The Farnborough Airshow in September 1957. Aerobatics are taught to military fighter pilots as a means of developing flying skills and for tactical use in combat. Many aerobatic manoeuvres were indeed developed in military conflicts, e.g. the Immelmann turn or Split S . Aerobatics and formation flying is not limited solely to fixed-wing aircraft; the British Army , Royal Navy , Spanish Air Force and

264-538: The Indian Air Force , among others, have helicopter display teams. All aerobatic manoeuvres demand training and practice to avoid accidents . Accidents due to aerobatic manoeuvres are very rare in competition aerobatics; most of them happen when performing formation flying or stunt flying at very low levels at airshows or air racing . Low-level aerobatics are extremely demanding and airshow pilots must demonstrate their ability before being allowed to gradually reduce

286-412: The armed forces while others are commercially sponsored. Coloured smoke trails may be emitted to emphasise the patterns flown and/or the colours of a national flag. Aerobatic maneuvers flown in a jet-powered aircraft are limited in scope as they cannot take advantage of the gyroscopic forces that a propeller driven aircraft can exploit. Jet-powered aircraft also tend to fly much faster, which increases

308-490: The "vaporization" of the uninhabited Marshall Island of Elugelab in the 1952 Ivy Mike thermonuclear test. Many other examples can be found throughout the various MythBusters episodes that have involved explosives, chief among them being Cement Mix-Up , where they "vaporized" a cement truck with ANFO. At the moment of a large enough meteor or comet impact, bolide detonation, a nuclear fission , thermonuclear fusion , or theoretical antimatter weapon detonation,

330-710: The Olympic games, and are governed by the FAI Aerobatics Commission (CIVA) Competitions start at Primary, or Graduate level (in UK "Beginners") and proceed in complexity through Sportsman (in UK "Standard"), Intermediate and Advanced, with Unlimited being the top competition level. Experienced aerobatic pilots have been measured to pull ±5 g for short periods while unlimited pilots can perform more extreme maneuvers and experience higher g levels -possibly up to +8/−6 g. The limits for positive g are higher than for negative g and this

352-420: 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,

374-434: The aircraft. Due to safety concerns, the smoke is not a result of combustion but is produced by the vaporization of fog oil into a fine aerosol , achieved either by injecting the oil into the hot engine exhaust or by the use of a dedicated device that can be fitted in any position on the aircraft. The first military aerobatic team to use smoke at will during displays was Fleet Air Arm 702 Squadron " The Black Cats " at

396-460: The height at which they may fly their show. In the EU, flying aerobatics requires special training and a rating. In Canada, no licence is required to perform aerobatics, but to carry passengers during aerobatics a pilot must have at least 10 hours dual flight instruction of aerobatic manoeuvres, or 20 hours of total aerobatic experience. Aerobatic flying competitions are a worldwide phenomenon, rather like

418-416: The pilot must wear a parachute when performing aerobatics. Aerobatic training enhances a pilot's ability to recover from unusual flight conditions, and thus is an element of many flight safety training programs for pilots. While many pilots fly aerobatics for recreation, some choose to fly in aerobatic competitions , a judged sport. In the early days of flying, some pilots used their aircraft as part of

440-472: The pressure of the environment. Sublimation is a direct phase transition from the solid phase to the gas phase, skipping the intermediate liquid phase. The term vaporization has also been used in a colloquial or hyperbolic way to refer to the physical destruction of an object that is exposed to intense heat or explosive force, where the object is actually blasted into small pieces rather than literally converted to gaseous form. Examples of this usage include

462-596: The rest of the season. The Red Checkers display team was disbanded following the arrival of the Beechcraft T-6 Texan II and retirement of the CT-4 Airtrainer. They were replaced by the Black Falcons , who fly the Beechcraft T-6 Texan II . Aerobatic Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term

484-416: The size of the figures and the length of time the pilot has to withstand increased g-forces. Jet aerobatic teams often fly in formations, which further restricts the maneuvers that can be safely flown. Aerobatics done at low levels and for an audience is called "stunt flying". To enhance the show effect of aerobatic manoeuvres, smoke is sometimes generated; the smoke allows viewers to see the path travelled by
