A landing gear assembly (12) includes a primary load bearing strut including a shock absorber having a slider part (15) arranged to slide within a cylinder part (17). A link assembly (50) is attached between the slider part (15) and the cylinder part (17). A bogie (16) supporting wheels is mounted on the strut. The bogie may adopt different pitch angles. A pitch trimmer device (70) is attached to the bogie and to the link assembly, for example thus providing a relatively long moment arm (96) for control of the bogie pitch angle. The arrangement may be such that the pitch trimmer (70) is near mid-stroke as the aircraft achieves the full weight on wheels condition, whereas the pitch trimmer is at a fullest extent for flight case and for retraction. Onset of pitch trimmer closure/movement is used to detect the weight-on-wheels condition.
