First approximation to take-off distance to 50 ft (15.2 m) for light and general aviation aeroplanes.
Abstract:ESDU 82033 provides a method to estimate in initial design or project studies the take-off distance to 50 ft (15.2 m) of light and general aviation aircraft from hard, level, dry runways in still air. ESDU 82033 can be used to estimate the engine powers and propeller thrusts required to achieve specified take-off distances and also allows the effects of changes in weight, lift coefficient, wing area, power or thrust on take-off distances to be investigated. The range of applicability includes all types of light and general aviation aircraft, for ISA sea level and a limited range of other ambient conditions. Two methods are given. A rapid method uses engine power to give estimates of the take-off distance for a restricted range of propeller-driven aircraft only. The other, more general method, requires the use of powerplant thrust in place of engine power and so embraces a greater variety of aircraft, including those powered by turbo-jet and turbo-fan engines. For each method "recommended lines" are given for different classes of aircraft together with an indication of the spread of the data used. The data were for 57 aircraft and 60 to 65 per cent lay within 10 per cent of the recommended lines.
