Pin bearing arrangement (10) for measuring loads in an aircraft landing gear (1), comprising a trailing arm (2), connected to at least one of the aircraft wheels (3), and a shock absorber (4), connected to the aircraft, whereby load (11) is transferred from the trailing arm (2) to the shock absorber (4), the trailing arm (2) being rotatable with respect to the shock absorber (4), the pin bearing arrangement (10) comprising at least one strain measuring element (12) attached to the pin bearing arrangement (10) in predetermined positions, these positions being selected such that the strain measuring element (12) gives at least a minimum detectable signal when the load (11) transferred is over a first threshold value, for any value of the angle (5) adopted by the trailing arm (2) with respect to the shock absorber (4). The invention also refers to a method for providing an indication of the on-ground condition of an aircraft, using a pin bearing arrangement (10) as the one described, and to a method for determining the positioning of the at least one strain measuring element (12) in such a pin bearing arrangement (10).
