EDITORIAL

The example of North Rhine-Westphalia

It is seldom the case that state initiatives in the area of General Aviation have deserved any praise – at any rate from the point of view of GA. In fact one might even wonder whether there had ever been such a case.
    But now the Land of North Rhine-Westphalia (NRW) has launched an initiative that is truly admirable. The ministry of finance and transport in Düsseldorf is providing around DM 1.7 million for the technical upgrade of "less common" aircraft powered by piston engines. The Land will bear the costs of certification and noise measurement, and aircraft operators based in NRW will receive direct financial support. With the manufacturer discounts on sound absorbers (Gomolzig, Heggemann, Liese) and propellers (Hoffmann, MT-Propeller) which have been agreed within the framework of this project, the subsidy could be as high as 50% of the costs!
    The Land authorities are not even insisting that the funds are used exclusively in North Rhine-Westphalia. Thus, three operators in Bavaria will also be beneficiaries. The aid will help to push forward upgrades which otherwise would probably never take place.

FEATURE

Runway on the River Spree

One of the attractions awaiting visitors to Germany's capital city is distinctly unusual: it is now possible to take off from the River Spree for sightseeing flights over the city with the "Duck zero one". From the water? That's right. "Duck zero one" is a Cessna 206 on floats and the only hydroplane in Berlin to be operated by Air Service Berlin for tourist flights. The popular aircraft is moored at Treptower Park, and it is not just the pilots who enjoy this new flying experience.

AIRCRAFT REPORT

Katana with Mid-West Wankel AE110

The Mid-West company from Egelsbach has installed a twin-rotor Wankel on a Katana DA20. Equipped with suction pipe injection, the compact unit has a power output of 105hp. The basic engine is already certified under JAR-E, but now the injection system needs to be JAR-certified as well. This could happen in 2001.
     The Mid-West Wankel offers a lot of redundancy, as is customary on aircraft engines. It has two ignition circuits, a redundantly designed Flytronic control unit, two manifold pressure, rotational speed and temperature sensors and two electric fuel pumps as well.
     The engine is easy to control. It manages without choke, carburettor heating or mixture control lever. Apart from adjusting the throttle lever, all the pilot has to do is operate the electrical propeller pitch control. As the engine rotates at up to 7,500 rpm, a correspondingly sharply reducing gearbox is installed. You will find out more about the aircraft performance and the special features of the Mid-West Wankel in the August issue of aerokurier.

Successful maiden flight of Akaflieg Munich's Mü 30

The Mü 30 Schlacro received its premiere in Königsdorf in the middle of June when Akaflieg (academic flying group) Munich presented its ambitious powered aircraft project in flight for the first time. The 300hp bolide is designed for use as an aerobatic aircraft with the additional capability of towing gliders.
    To mark the occasion of its maiden flight, the Akaflieg put on an air display. They were lucky with the weather as well. The Mü 30 was flown by Akaflieg veteran Helmut Fendt, who today works at the German Civil Aviation Authority. As a student he had been closely involved in the launch of the aircraft at the beginning of the 1980s. The design of the combined glider tug and aerobatic aircraft was the subject of his dissertation.

New MCR 4S four-seater derivative

On 14 June Christophe Robin's new four-seater low-wing MCR 4S, a derivative of the MCR 01 two-seater, had its maiden flight in Dijon-Darois. By the middle of July the prototype had already clocked up 50 hours of flight trials. The common ground between the MCR 01 and the MCR 4S comes to an astonishing 75%.
    The empty weight of the prototype low-wing monoplane is only 327kg. The maximum take-off weight is fixed at 750 kg. If one subtracts the standard fuel quantity of 120 litres from the MTOW, the useful load is 338kg. This moves the MCR 4S into the camp of the real four-seaters. The engine options include Rotax and JPX, with 100 to 120hp. It is estimated that at 75% capacity the aircraft should do 280 km/h at FL80. At full throttle it should even achieve up to 320km/h at 11,500ft.
   DynAéro, the company which manufactures the pioneering new Robin aircraft, has already received some orders for the MCR 4S. First delivery of the kits is expected shortly.

Helicopter for the 21st century

At the 22nd Helicopter Forum in Bückeburg experts discussed the future prospects of the rotorcraft under the theme "The future does not stand still". According to a study by the University of Maryland in collaboration with NASA (presented by George Price), it is only in the last five years that serious improvements for the efficient and economic use of helicopters have begun to make themselves felt.

TRAVEL

Flying in southern Africa

Stellenbosch in the Cape Province of South Africa was the departure point and destination for Gerhard Obernosterer and three friends who together flew through southern Africa in a Piper PA-28. They flew over the Skeleton Coast in Namibia, the Etosha Pan, the Okavango, the Victoria Falls and the Cape of Good Hope. As most of the airfields in this part of the world are on high plateaux and their density altitude is not infrequently 7,000 to 8,000ft, the pilots had to always calculate their take-off weight extremely accurately.

FLYING

Taylorcraft BC-12-D

Taylorcrafts have always stood in the shadow of the highly successful Piper Cubs. David Deiss owns a Taylorcraft and has made the leap from model builder to private pilot in an unconventional way. He blames his experience as a passenger on a 1946-built BC-12-D. The consequences were predictable: the single-engined veteran aircraft impressed Deiss so much that he then bought the plane off his friend along with the necessary training, as Deiss did not have a licence.

PRACTICE

Landing after-hours

What happens if a pilot lands on an airfield after the official opening times? We confronted the regional administration of Düsseldorf with a fictitious flight and asked them to treat the flight as if it were genuine. We were eager to know what the "judgement" of the authority would be on this matter. They accepted that landing after-hours might be necessary on grounds of safety, but we felt that the DM1,000 fine on the grounds of gross negligence was a bit steep and hard to understand.

Meteorology: interpretation of soundings

Measurement of changes in temperature, or soundings, can tell one a lot more about the stratification of the atmosphere and the resulting weather than one might think.
    The interpretation of soundings is still as important as ever from the point of view of aeronautical meteorology. So it is unfortunate that tailored products such as Top-Therm or the convection maps which are provided via pc_met are only available for Germany and the Alps. How do I assess thermal conditions and do my flight preparation if I am abroad? Convection analysis based on soundings is actually more accurate than Top-Therm or convection maps. A guide to sounding analysis.

Accident analysis: "life-saving" equipment proved a time bomb

The automatic release of the emergency parachute in the cockpit of a Pilatus Porter resulted in the death of two pilots. While the pilot was wearing a compact emergency parachute, the co-pilot had a training parachute on which was fitted with an activated emergency reserve. As the Porter descended through 300m, losing altitude at a rate of over 13m/s, after dropping off some parachutists, the reserve suddenly deployed. The co-pilot was pulled out of the rear door of the aircraft by the energy of the parachute opening. The parachute got caught in the empennage and tore off parts of it, following which the Porter could no longer be controlled and crashed.

ULTRALIGHT

Aircraft report: the new Dynamic

A new high-performance ultralight aircraft has been announced. The new WT9 Dynamic could put the competition into the shade. The WT9 Dynamic ultralight aircraft which Rudolf Schäfer, head of Ikarusflug, is launching on the German market is clearly aimed at taking the lead in the performance leagues for this class.
   We went to look at the prototype of the phenomenal low-wing aircraft at the manufacturer's in Prievidza, Slovakia, a good four hour journey by car to the north-east of Vienna. As one can tell from its lines, the Dynamic is heavily influenced by the Pulsar and Lancair kitplanes, a few kits for which were built by a partner company of Aerospool in Bratislava. Nevertheless, the new low-wing monoplane has a completely new construction.

New smart ultralight engine soon to be airborne

After more than a year of trials, the 55hp three-cylinder engine from the "smart" city car is finally poised for its market launch as a powerplant for ultralights. B & F is the first manufacturer to offer the modern turbo-engine for the FK 9 MK II. Light, quiet and environmentally friendly with advanced technology.
     The objectives for the new ultralight engine were clear from the beginning. That the smart Suprex M 160 is now poised for market launch is the outcome of a multi-partner collaboration involving the EFK Flugschule, UL-Technik Otto Funk, DaimlerChrysler/Micro Compact Car Smart (MCC) and the UL manufacturer B & F.
    The compact, liquid-cooled three-cylinder four-stroke 599cc engine produces 55hp at 5,250rpm. Modifications in the control software for the series engines mean that the initial output is raised to 60hp, then after 50 seconds the electronics adjusts it downwards back to 55hp continuous output. This is not exactly generous for the latest generation of ultralights, but it makes the smart turbo-engine an attractive prospect, for example, as a replacement for many older models.

German ultralight championships

The 15th German Ultralight Championships, held between 22 and 24 June in Kulmbach, produced three exciting competition days. The suspense was kept up right through to the finish. Twelve three axis teams, 14 trikes and 7 powered paragliders competed in their classes. After three navigation flights and two precision landing competitions the competition experts took up their place on the platform once again. Heinz Korella (partnered by Walter Wolfram) defended the title he had won the previous year in the two-seater three axis class, while Jan took the title in the one-seater class.

GLIDING

German Open Class Championships

Wolf-Dietrich Herold, who took part in the German Championships in Mengen from 28 May to 11 June in his ASW 22 "1E" and, despite a wing span handicap (22m), obtained the best score on one of the days, reports from the Open Class. (Results Open Class )

Way ahead of the pack in the LS8/18

In the 18m class competition at the German Championships, Mengen, Claus Triebel caused quite a sensation with his standard class LS8 aircraft which had been stretched into an18m wingspan: not only did he manage to keep up with the fastest flapped aircraft, but he won convincingly as well. He finished the competition a good 100 points ahead of Bernd Gauger's LS6-18w, of which the Rolladen Schneider RS LS8/18 was a derivative. In third place came Martin Staiger, flying a pure glider (DG-800S). (Results 18 m Class)

Club Class SPECIAL

The Club Class SPECIAL event in Weissenburg, which had a very good entry, was accompanied by very difficult weather conditions, but the numerous competitors rated it a great success.
   The Club Class SPECIAL is a competition exclusively for club class aircraft. It is aimed at attracting all sorts, from the very best pilots in Germany through committed competition pilots to absolute beginners, to a central flying venue. The event was attended by three pilots from the current "A" squad: European champion Frank Hahn (ASW 15), Bernd Nübling (ASW 19) and Axel Reich (Standard Libelle). Other competitors included Joachim Kuhlmann, holder of the Barron-Hilton Cup, and numerous junior pilots, above all from Baden-Württemberg. Altogether an impressive 43 pilots took part.

High-tech launch machine

It had to be reliable and at the same time enable automatically controlled launches. These were the requirements which the Aukrug Flying Club drew up for the new launch winch which the members planned to build themselves while keeping the costs down.
   They have brought off a masterpiece. The new launch winch has been in use since the beginning of the 2000 season. The launch device places next no requirements on the winch driver, who only has to select the glider type and the head wind component. Everything else is performed "digitally", with the throttle control simply pushed forwards after the "rope taut" command. The winch conveys the glider up into the sky with constant cable pull, automatically controlled.
    The Aukrugers have implemented their ideal winch with a combination of diesel and hydraulic power. A 320hp lorry diesel engine generates the necessary power in the hybrid drive in the optimal operating range (1,800rpm). The force is transmitted to the cable drums by hydraulics – a directly flanged large pump and hydraulic motor. Use of hydraulics has a number of advantages. In this way the hydrostatic drive creates a torque that is independent of the rotational speed. The rotational speed of the cable drums is infinitely variable, and this is controlled via corresponding electronics.

Alarming decline of gliding (part 3)

What are the reasons for the decline in the number of active glider pilots, a phenomenon which is affecting gliding all around the world? How can the trend be arrested? Fred Weinholtz presents the views of John Roake, New Zealand, (aerokurier 6/2000) in relation to gliding as it is organised in Europe.

DAeC 50th Anniversary

Aerosports successes: international comparisons

Germany is one of the biggest and most successful aerosports nations of the world. Internationally, the seven specialist aerosports groups represented in the Deutscher Aero Club (DAeC) are always among the front runners both in the European and world championships.
     After 50 years it is still difficult for the DAeC to sum up the many sporting successes, as the list of the best has meanwhile grown so big. An overview.

DAeC chronicle: strength from unity

It was on 4 August 1950 that the umbrella organisation of aerosportsmen in Germany, the Deutscher Aero Club (DAeC), was founded in Gersfeld/Rhön.
     It was no simple undertaking to launch an aerosports association, as at that time aerosports were subject to the stringent conditions imposed by the Allied occupying powers. Unlike other types of sport, it had to establish and maintain its sporting significance, its social weight and its civilian interests against the resistance of the occupying powers. A retrospective view.

The sporting specialities in the Deutscher Aero Club

What does flying mean? In the Deutscher Aero Club it is practised in a wide variety of forms, with seven different types of aerosport united under the one umbrella organisation. We introduce the seven aerosports specialities.

Start of the new era of gliding

Two months after gliding was allowed once again, the "Rhön 1951" became the first big flying festival in the history of the Deutscher Aero Club. A newspaper report from those days describes the mood and provides an overview of the licensing system and the gliders that were available at that time.

Interview: more lobbying work and more effective clubs needed

The Deutscher Aero Club looks towards the future without forgetting the past. DAeC President Wolfgang Weinreich spoke to aerokurier about problems and prospects for aerosports.
