Landing gear for amphibious helicopter and aircraft in which flotation is provided by the fuselage proper, and for which it is necessary to provide transverse balancing, characterised in that it comprises: a main landing gear, articulated onto the fuselage by means of a shaft 22 which is inclined in the horizontal plane and consists of two half-landing gears whose respective leg 14 is provided with a wheel 16 and with a fairing in the shape of a float 18 the capacity of which is defined by the conditions for equilibrium when afloat; a system 24 for controlling the articulation of the main landing gear, in order, starting from the landing position on the ground, to define a position for the wheel and for its fairing which is compatible with the stability conditions when afloat, and to obtain correct incidence of the float when hydroplaning, taking account of the inclination of the said articulation shaft 22; and an auxiliary landing gear, providing steering on the ground, which is provided with a rudder consisting of the fairing of the wheel of this auxiliary landing gear, which, when it is immersed during movement afloat, provides steering for the apparatus. <IMAGE>
