The semi-span wing flaps are of slotted design and are effective in all flight regimes. The 15 degrees ‘Take-Off’ position assists with early rising of the tail and main wheel lift off, thus reducing take-off ground roll significantly. At a hopper payload of 1050 kg the ground roll has been measured at approximately 420 metres (1380 ft) with zero wind and 15 degrees Celsius at sea level. Full flap (38 degrees) allows a landing approach speed of approximately 50-55 knots at light weight. This allows comfortable short field landings with a typical ground roll of 200 metres (650 ft). The wing flaps can also be used in flight in agricultural operations and significantly reduce turn radius when the aircraft is fully loaded. Another important design feature of the flap system is that there is no noticeable change in pitch trim with the extension of the flaps. This has been achieved by the incorporation of a simple interconnect system which applies bias to the elevator trim springs when the flap are extended. Ailerons: The ailerons are gap sealed and provide light and responsive behaviour to minimise pilot fatigue. The ailerons allow a high roll rate of approximately 3 seconds from 45 degree bank through to 45 degree bank the other way at normal working airspeeds. This is unique to the GA200. Wing Tips: These are removable assemblies to allow easy replacement in the event of damage. Their shape has evolved over a number of years of “in the field” testing to provide the best possible swath width without compromising aircraft performance, and maintaining small, controlled wingtip vortices. Fuselage The fuselage structure is a welded SAE 4130 chromium molybdenum steel tube assembly. The design has been optimised for maximum strength-to-weight ratio by using finite element computer analysis methods. The forward fuselage has been designed to progressively crumple in the event of a sudden forward deceleration. Metal side panels attached by half turn ‘Dzus’ fasteners are fitted to both sides of the fuselage from the engine bay back past the rear cockpit. These allow ready access for ease of inspection, maintenance and cleaning. Additionally the rear fuselage upper turtledeck is easily removed for rear fuselage inspection, maintenance and cleaning. The configuration of the pilot behind and above the load has been used. A second seat for transporting the loader driver or to allow aerial viewing by the farmer has been a long requested
