CS-VLA 427 Unsymmetrical loads

• ED Decision 2003/18/RM found in: CS-VLA Amdt 1 - Very Light Aeroplanes (Mar 2009)

CS-VLA 427 Unsymmetrical loads ED Decision 2003/18/RM (a) Horizontal tail surfaces and their supporting structure must be designed for unsymmetrical loads arising from yawing and slipstream effects, in combination with the loads prescribed for the flight conditions set forth in [CS-VLA 421](#_DxCrossRefBm584936705) to [425](#_DxCrossRefBm584936708). (b) In the absence of more rational data for aeroplanes that are conventional in regard to location of the engine, wings, tail surfaces, and fuselage shape - (1) 100% of the maximum loading from the symmetrical flight conditions may be assumed on the surface on one side of the plane of symmetry; and (2) The following percentage of that loading must be applied to the opposite side: % = 100-10 (n - 1), where n is the specified positive manoeuvring load factor, but this value may not be more than 80%.
