An unmanned aircraft system (UAS) to inspect equipment and a method of inspecting equipment with the UAS are described. The UAS includes a scanner to obtain images of the equipment and a memory device to store information for the UAS. The UAS also includes a processor to determine a real-time flight path based on the images and the stored information, and a camera mounted on the UAS to obtain camera images of the equipment as the UAS traverses the real-time flight path.
