1. An aircraft landing gear comprising:
a stationary element and at least one movable element which can move relative to the stationary element between a first position and a second position, and detection means arranged to detect when the movable element is in at least one of its positions,
wherein the detection means comprise at least one threadlike and flexible shape sensor, connected to an electronic processing unit arranged to deduce the position of the movable element of the shape of the shape sensor, and
the shape sensor comprising a first section rigidly connected to the stationary element and a second section rigidly connected to the movable element so that the first section and the second section are immobile with respect to the stationary element and the movable element respectively, and are movable relative to one another.
