Abstract: An aerodrome maintenance apparatus for monitoring runway and taxiway conditions and remotely reporting the status of the runway or taxiway. The apparatus comprises: a drive unit arranged to mount one or more rails to provide movement of the apparatus along the one or more rails; a detection unit comprising one or more sensors configured to detect one or more parameters of the runway or taxiway; and a communications unit arranged to transfer data derived from the detection unit from the apparatus to a remote server. The apparatus is arranged to advance along the one or more rails and transfer data representative of one or more parameters of the surface to a remote server.
