Abstract
A landing gear assembly () includes a primary load bearing strut including a shock absorber having a slider part () arranged to slide within a cylinder part (). A link assembly () is attached between the slider part () and the cylinder part (). A bogie () supporting wheels is mounted on the strut. The bogie may adopt different pitch angles. A pitch trimmer device () is attached to the bogie and to the link assembly, for example thus providing a relatively long moment arm () for control of the bogie pitch angle. The arrangement may be such that the pitch trimmer () 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.
