The Hutter H17 is a small single seat glider with a wing span of 9.69 metres, designed in 1934 by Wolfgang Hutter, for flying in the Austrian Alps. Construction of the museum’s example, “Sweetwings” (now registered as VH-GQM), commenced in Perth in 1949. It is one of two Hutter H17 gliders built in Western Australia by N.J. Wynne and A.G. Milligan at the time – the other “Fleetwings” (formerly VH-HDQ and since re-registered as VH-GXV) is located at Millicent, South Australia. Ownership transferred to G.R. Reichelt of Tocumwal New South Wales and later to D.B. Hunt of Thornbury in Melbourne and later Mt Isa, Queensland. It was acquired by Bill Riley of Tocumwal who donated it to the Museum. The glider was last flown on 25 October 1979 at Tocumwal. This exhibit is an example of a 1930s small wood and fabric glider that was designed in Austria for hill soaring. It is a simple design that became a popular choice for home building in the post war years in Australia when gliding as a sport was in recovery. Some examples are still flying.Small single seat glider. Fuselage and wing struts are painted yellow. Wings, rudder and tailplane / elevator are primed with pink dope. It has an open cockpit with small clear Perspex wind screen. Instruments include airspeed indicator and altimeter tucked neatly under front edge of the cockpit rim.australian gliding, glider, sailplane, hutter, sweetwings, fleetwings, reichelt, riley, wynne, milligan

This aircraft is one of 9 single seat ES 59 advanced club sailplanes manufactured by Edmund Schneider Pty Ltd in the 1960s. It was first flown in August 1963 and delivered to the Darling Downs Soaring Club at Toowoomba Queensland. At that Club it had 2603 flights and recorded a total airtime of 1475 hours. In addition to many local circuits and soaring and cross country flying, it was used at gliding competitions, including Nationals at Benalla in December 1964, State Championships at Oakey in April 1965, at Warwick in April 1966, and at (Inverell?) in March 1967. On at least 15 occasions flight times in excess of 5 hours duration were achieved. On 5 October 1970, the glider had a new life when it was relocated to Wollongong in New South Wales. It recorded 1927 flights with a total airtime of 1179 hours at the club between October 1970 and June 1988. Competition appearances included the State Championships held at Forbes in January 1972. Places away from Wollongong where the glider was launched include Cootamundra, Wagga, Temora, Marulon, Narromine, Leeton, Nowra, Goulburn, Horsham, Greenthorpe. On 15 June 1988 it was transferred to Ron Geake who transported it to Warrego in Northern Territory (flown once at Alice Springs), and then to Gympie in Queensland where it was flown about 20 times by the end of 1995. It was also flown on a small number of occasions at Forbes in New South Wales in 1996 and 1997. During 1998 and 1999 the glider was sparsely used (9 flights) at locations that have not been recorded. From May 1999 until transfer to the Australian Gliding Museum in May 2011 it apparently was not flown. Aggregate airtime hours for the glider stand at 2702 hours 53 minutes. It has been launched 4569 times. A good example of a Schneider ES59 sailplane from the 1960s. This type is of note because it was the first Australian designed and built sailplane to be used in a world gliding competition (Jack Iggulden in Argentina in 1963). This Schneider ES59 Arrow is a single seat wooden sailplane with one piece wing. The instruments are not present except for altimeter. Fin and rudder are of swept back design. Colour scheme is white with lemon yellow fuselage underbelly. The aircraft came to the museum on an open trailer that had been designed to carry the one piece wing.

The “Coogee” is an intermediate single seat sailplane designed and built by Tom Proctor in 1940. Only one was built. It was first flown at Stuart Hill near Bendigo Victoria in January 1941 and was maintained in flying condition until 1967. The aircraft was flown extensively by the Victorian Motorless Flight Group (now the Melbourne Gliding Club) and Geelong Gliding Club and several subsequent owners. This exhibit is a "one off" Australian designed and built glider similar in some respects to the Hutter H17. Its usage is relevant to the history of gliding in Victoria in the post war years. Also the aircraft provides an insight into gliding technology in Australia in the 1940s. Wood and fabric single seat glider sailplane with strutted wings and strutted tailplane – features metal framed perspex canopy, central fuselage skid and wheel, small tail skid, instruments include airspeed, turn and bank indicator; variometer and altimeter.

This set of map prints was assembled as a training aid. The collection is a complete set of individual color prints of each colour used on the final printed maps for each map Joint Operations Graphic (JOG) JOG Ground and JOG Air versions. This map series was produced in two versions to help coordinate military Ground Operations and Air Operations. The ground users required that heights and measurements were in Metres, whilst air users required height information in Feet for altimeters. The Air Version also contained more Aeronautical information including safe flying height information called Maximum Elevation Figures (MEF). Later printing of JOG incorporated printing in just four colours Cyan, Magenta, Yellow and Black (CMYK).

The Slingsby T31 is a two seat training glider that came available in 1951. It is, in effect, a two seat version of the single seat Kirby Tutor. The T31 was marketed by Slingsby Sailplanes both as complete aircraft and kits of parts for assembly. The Australian Gliding Museum’s example (currently registered as VH-GDB) is one of five of this type to grace Australian skies. Three including GDB were assembled in Australia from kits supplied by Slingsby’s in England, the other two were delivered as completed airframes. To date only four remain of which two are airworthy. This aircraft began flying in at Caversham in Western Australia (the then home of the Gliding Club of Western Australia) in July 1956. It was badly damaged in a crash in June 1958. The wreckage was sent to Schneiders in Adelaide for repair. However, the Club decided against having the repairs done, opting instead to buy a new ES52 Kookaburra. After a couple of years, the wreck was purchased by a member of the Waikerie Gliding Club whereupon the glider was rebuilt with some modifications, including a more rounded and better streamlined fuselage nose. It returned to the air in October 1961 at Clare in South Australia. The ownership of VH-GDB passed through a number of clubs, including at Dubbo in New South Wales, Wimmera in Victoria and Pioneer Valley at Mackay in Queensland. Eventually, it came into the hands of Bill Riley of Tocumwal in New South Wales who held it in storage for many years. Riley donated the aircraft to the Museum. It has been restored to airworthiness and is flown at vintage glider rallies and on Museum open days. This exhibit is an excellent example of a Slingsby T31 Tandem Tutor, a type of glider that was used by a number of clubs in the 1950s and 1960s for dual training of pilots to the solo capability.The Slingsby T31b Tandem Tutor is an open cockpit, tandem, two-seater glider with high, pylon mounted two piece wing supported by double, wire braced, steel tube struts. The glider is fitted with a main wheel, rubber-block sprung, wooden nose skid and steel leaf sprung, brass shod tailskid. The basic controls of aileron, rudder and elevator are not supplemented with pitch trim. Wing lift spoilers and both aerotow and winch releases are fitted. The instrument panels in both cockpits are fitted with an airspeed indicator, cosim variometer and altimeter. This red and silver painted wood and fabric covered aircraft is in excellent condition having been restored to full airworthy status by the Australian Gliding Museum.

This unique aircraft was conceived in 1943 as a two seat trainer. A very large part of the design work can be attributed to Jock Barratt and Harold Bradley. The general layout adopted is similar to the Kite I and Kite II single seat sailplanes of Martin Warner and Allan Campbell. Having regard to this heritage, the glider was originally named Kite III but renamed Pelican 2, perhaps because it was the second two seat training glider built by the Waikerie Gliding Club – the first being the Pelican, a reconfigured Pratt Utility glider. Pelican 2 was first flown in 1952 and regularly since then, at least until about 1992. The Pelican 2’s performance was found to be very good for sailplanes of its era and was often used for more advanced flying in addition to training new pilots. Very few changes have been made to the Pelican 2 over the years. The undercarriage was modified after its initial testing to improve the placement of the wheels. The trailing edge of the rudder (originally straight) was rounded adding to the surface area. The twin shoulder tow line bridles were replaced with a belly hook when aviation design rules declared shoulder bridles dangerous and a nose hook has since been added to allow for aero-towing. A unique home grown sailplane design associated with Australian gliding pioneers Wooden 2 seat glider sailplane with fabric covering. Distinctive features include the pod and boom fuselage with side by side seating for pilot and a second person. The canopy of perspex supported by aluminum framing opens with port and starboard segments separately folding upwards and forward. The instrument panel includes altimeter, airspeed indicator, slip indicator and variometers. In addition to the usual controls, there is a trim operated by a small wheel mounted centrally, at head height, on the bulkhead at the rear of the cockpit. Incorporated in the skid under the fuselage pod are two wheels (one approximately midships and the other at the rear end). It has a three piece cantilever wing of approximately nearly 17 metres. The ailerons run almost full length of the outer wing segments. A Gottingen 426 section has been used changing to M6 at the tips. Outer wing segments are joined to the centre section to give about 300 mm of dihedral at the tips. The glider is equipped with airbrakes. The colour scheme consists of orange fuselage with black nose and skid. The tailplane / elevator and rudder are painted white. The wing is predominantly white with an orange leading edge. Registration VH-GFY On each side of rudder – “Pelican II” in black lettering on a rectangle of silver On each side of fuselage pod the letters ‘FY’ On each side of the fuselage, below the edge of the cockpit opening – “WAIKERIE” in black paint. australian gliding, glider, sailplane, kite, pelican, waikerie gliding club, jock barratt, harold bradley, martin warner, allan campbell

This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.

Of Particular note these charts were used to plot "Rhumb Lines or loxodromes" where a course crosses all Meridians (Lines of latitude and longitude) at the same angle. On Mercator projection charts Rhumb lines are conveniently shown as straight lines and are also lines of constant compass bearing. Rhumb lines are usually longer than the shortest distance between two points. The shortest distance between two points on the earth's surface is called a "Great Circle Route" which is a route on a circular path on the surface of the earth where the centre of that circle is also the centre of the earth. Great Circle Routes on a Mercator Projection are however curves and harder to plot. These charts were produced and printed at the Army Survey Regiment, Bendigo. .5 RAAF LONG RANGE PLOTTING CHART.
