CS 22.479 Level landing condition ED Decision 2003/13/RM (a) For a level landing, the sailplane is assumed to be in the following attitudes: (1) For sailplanes with a tail skid and/or wheel, a normal level flight attitude. (2) For sailplanes with nose wheels, attitudes in which – (i) The nose and main wheels contact the ground simultaneously; and (ii) The main wheels contact the ground and the nose wheel is just clear of the ground. (b) The main gear vertical load component PVM must be determined to the conditions in [CS 22.725](#_DxCrossRefBm2056272163). (c) The main gear vertical load component PVM must be combined with a rearward acting horizontal component PH so that the resultant load acts at an angle at 30° with the vertical. (d) For sailplanes with nose wheels the vertical load component PVN on the nose wheel in the attitude of sub-paragraph (a)(2)(i) of this paragraph must be computed as follows and must be combined with a rearward acting horizontal component according to sub-paragraph (c) of this paragraph taking into account [CS 22.725(a)](#_DxCrossRefBm2056272163):  where: m = mass of the sailplane (kg) g = acceleration of gravity (m/s2).
