Landing gear for an aircraft comprises a telescopic shock absorber strut 1, an arm 4 (eg bogie beam) carrying landing wheel(s) 7, 71 and pivotally connected by a main pivot 5 to the lower portion 3 of the shock absorber strut, and a load reacting unit 9 connected 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 or between the arm 4 and the lower portion 3 of the shock absorber strut to act as a pitch trimmer (fig.7). The load reacting unit 9 preferably comprises a fluid pressure unit and the indicator 60 comprises a mechanical indicator that operates at a predetermined pressure threshold. The indicator may comprise a brightly-coloured bobbin (62, figs. 2-4) sliding in a bore (63) and having a barrel-shaped shoulder (70) which engages a spring-biassed detent (67). |
