Dynamic (Yeoman Light Aircraft Co)

The Dynamic is an advanced light-weight aeroplane with comfortable dual side-by-side seating. Conceived in 1996, the Dynamic has been in serial production since 2000, and by 2005 over 100 were flying in more than 19 countries around the world, including France, Germany, the Netherlands, the USA, Canada, South Africa and New Zealand.

The use of advanced construction techniques and state-of-the-art materials, including sandwich shells and carbon fibre composites, means the Dynamic's weight has been kept very low, with the baseline UK variant weighing in at an astonishing 254kg.

The aeroplane is powered by the ubiquitous Rotax 912 engine, representing the very best of Austro-Canadian engineering. The basic model of the aeroplane is equipped with a Rotax 912 UL engine, with a power output of 80hp (60kW), whilst the more sporty 912 ULS, rated at 100hp (80kW), is available as an option. Either way, the engine has two carburettors, electric starter, double ignition, stainless exhaust, and a silencer. A variety of propeller options are available, including electrically controlled variable pitch.

The fuselage of the Dynamic consists of composite sandwich shells, where carbon fibre plays the key role. This allows a low weight coupled with high strength and rigidity. The fuselage also includes a 2.45m (8ft) wide centro-plane, including integral fuel tanks with a total volume of 75l (16.5 imp gal). The horizontal fin has the same span as the centro-plane, an elegant design feature which facilitates containerised transport of a dismantled aeroplane.

Control is effected via a classical control column (i.e. 'joystick', not control yoke), fitted to both sides, and rudder pedals. In order to provide maximum control of the aircraft configuration in the unlikely event of an electrical failure, the control of flaps and trim is mechanical, with the controls between the seats of the pilots.

The frame of the canopy is made of carbon composite, which ensures high strength and rigidity. Sector-leading levels of in-flight comfort are ensured in a true ergonomically designed cockpit. The internal width of the cockpit is 115 cm (3'9"), which is the widest in the category. An excellent view from the cockpit is ensured by the use of organic glass made by Swiss fibreglass producer Mecaplex.

The instrument panel is fitted with basic engine and flight instruments as standard, however a very wide range of options is available, from almost any conceivable additional instrumentation, right up to a glass cockpit with full colour primary flight display (PFD).

Perhaps the most striking feature of all about the Dynamic, and one which has won it critical acclaim the world over, is the quality of build and surface finish. Every part is manufactured with the highest conceivable attention to detail, whilst the finish of the fuselage and wings sets a new standard in composite aircraft production. It is quite literally possible for a gentleman to shave using the wing as a mirror. The Dynamic really shows its shared heritage with glider design and production, which plays no small part in achieving its dazzling performance figures.

The aircraft can be supplied with  a fixed tri-cycle or retractable undercarriage and is also available as a kit.
