Abstract

A landing gear for an aircraft includes a shock absorber strut (1) with upper and lower telescoping portions (2, 3), the upper portion (2) being connectable to the airframe of the aircraft. An arm (4) extends fore and aft relative to the aircraft and carrying a landing wheel, (7, 7.sup.1), and pivotally connects by a main pivot (5) to the lower portion (3) of the shock absorber strut. A load reacting unit (9) connects between the arm (4) and the shock absorber strut (1) for reacting to load applied between the arm and shock absorber strut on landing. An indicator (60) monitors the load applied to the load reacting unit (9) on landing. The load reacting unit (9) may be connected between a forward end of the arm (4) and the upper portion (2) of the shock absorber strut to make the gear act as a semi-levered landing gear. Alternatively, the load reacting unit (9) may be connected between the arm (4) and the lower portion (3) of the shock absorber strut to act as a pitch trimmer. The arm (4) may include a bogie beam with fore and aft landing wheels (7, 7.sup.1) with the main pivot (5) therebetween. The load reacting unit (9) preferably has a fluid pressure unit and the indicator (60) includes a mechanical indicator that operates at a predetermined pressure threshold.
