Celstar GA-1
The Celair GA-1 Celstar is a South African mid-wing, single-seat, aerobatic glider that was designed by Pieter Celliers and produced by his company, Celair (Pty) Limited. Design and development The GA-1 was especially intended for flying competitive glider aerobatics and the resulting airframe was designed to Joint Aviation Requirements 22 standards and stressed to 10 g. The aircraft is made from a combination of fibreglass and aramid. Its span wing employs a Wortmann FX-71-L-150/25 airfoil. The ailerons are full-span and mass-balanced. Dive brakes are used for approach control. At least eight were produced, with two exported to Switzerland and six to the United States. Operational history In August 2011 there were two GA-1s registered in the US with the Federal Aviation Administration The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrou ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Dive Brake
Dive brakes or dive flaps are deployed to slow down an aircraft when in a dive. They often consist of a metal flap that is lowered against the air flow, thus creating drag and reducing dive speed.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 168. Aviation Supplies & Academics, 1997. In the past, dive brakes were mostly used on dive bombers, which needed to dive very steeply, but without exceeding their red line speed, in order to drop their bombs accurately. The airbrakes or spoilers fitted to gliders often function both as landing aids, to adjust the approach angle, and to keep the aircraft's speed below its maximum permissible indicated air speed in a vertical dive. Most modern combat aircraft are equipped with air brakes, which perform the same function as dive brakes.

1980s South African Sailplanes
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Swift S-1
The Swift S-1 is a single seat aerobatic glider manufactured by Polish company Swift Ltd. Design and development Edward Margański, Jerzy Cisowski and Jerzy Makula developed the Swift at Bielsko-Biała from the SZD-21-2b Kobuz 3. The prototype first flew in 1991. The glider is made of glass-fibre epoxy composite. It is very strong (stressed for plus and minus 10g) and manoeuvrable (a roll takes less than 4 seconds). Larger tips to increase the span to 15m were designed but not made. It has a retractable undercarriage.

Pilatus PC-11
The Pilatus B4-PC11 (also known as the PC-11 in the Pilatus numbering sequence) is an all-metal intermediate glider built by Pilatus Aircraft of Switzerland. The B4-PC11 is designed to Standard Class specifications, meaning that it has a 15-metre wingspan and no flaps. Air brakes are provided on the top surface of each wing for glidepath control. Construction is aluminium, with foam ribs in the mainplane, fin and tailplane. Development The design of this glider originated in the 1960s, when the company Firma Rheintalwerke G. Basten (from which the "B" in the original designation is derived) manufactured the first two prototypes. The designers were Ingo Herbst, Manfred Küppers and Rudolf Reinke. The first flight of the first prototype took place on 7 November 1966. However, no series production was started. In 1972 Pilatus bought the manufacturing licence for the B-4 and renamed it the B4-PC11. In the spring of the same year the first production example (numbered HB-1100) mad ...

Glasflügel H-101
The H-101 ''Salto'' ('Loop') is an aerobatic glider of glass composite construction, developed in Germany in the 1970s. Based on the Standard Libelle H-201, it was designed by Ursula Hänle,Coates 1978, p. 101. widow of Eugen Hänle, former Director of Glasflügel. It was first produced by Start + Flug GmbH Saulgau. Design and development The H-101 differs from the Libelle in having a V-tail, showing its ancestry to the V-tailed Hütter H-30 GFK. Four flush-fitting air brakes were fitted to the trailing edges of the wings, replacing the more conventionally sited air brakes of the Standard Libelle. The Salto's air brakes are hinged at their midpoints so that half the surface projects above the wing and half below. The Salto prototype first flew on 6 March 1970, and 67 had been delivered by early 1977, when production at Start + Flug GmbH Saulgau ceased. Five more Saltos were built from 1993 to 1996 by the German company "LTB Frank & Waldenberger", bringing total output of Salt ...
