            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.
