**Sec. 25.485 - Side load conditions.**
In addition to §25.479(d)(2) the
following conditions must be considered:
(a) For the side load condition, the
airplane is assumed to be in the level attitude with only the main wheels
contacting the ground, in accordance with figure 5 of appendix A.
(b) Side loads of 0.8 of the vertical
reaction (on one side) acting inward and 0.6 of the vertical reaction (on
the other side) acting outward must be combined with one-half of the
maximum vertical ground reactions obtained in the level landing
conditions. These loads are assumed to be applied at the ground contact
point and to be resisted by the inertia of the airplane. The drag loads
may be assumed to be zero.
