The invention belongs to the technical field of aircraft landing gears, and particularly relates to an aircraft landing gear position state indicating system which comprises a signal lamp box indicating subsystem, a signal lamp indicating subsystem and a mechanical indicating subsystem. The starting and lamp box indicating subsystem is characterized in that a main power supply is connected with a closing position microswitch and a putting position microswitch through a main circuit breaker and supplies power to the closing position microswitch and the putting position microswitch; the putting-down position microswitch and the putting-up position microswitch are connected with the landing signal lamp displayer and the parameter sending displayer. The signal lamp indication subsystem is characterized in that a standby power supply is connected with an up-position microswitch and a down-position microswitch through a standby circuit breaker and supplies power to the up-position microswitch and the down-position microswitch; the up-folding position microswitch and the down-folding position microswitch are further connected with a signal processor, and the output end of the signal processor is connected with a white indicating lamp. The mechanical indication subsystem comprises a main landing gear mechanical indication system consisting of a main shock strut, a pull rod transmission mechanism, a spring and a red mechanical indicator which are connected in sequence; the front shock strut, the foldable inclined strut mechanism and the position indicating pointer are connected in sequence, and the position indicating pointer is matched with the marking line area to form a nose landing gear mechanical indicating system.
