Abstract
An eyeline sighting device includes a base portion for placing the device on a working surface and a top portion for visual alignment. The top portion includes a frame, at least one level for adjusting the position of the frame relative to a horizontal plane, a first sighting element, and a second sighting element. The pilot's position is adjusted until the second sighting element is brought into alignment with the first sighting element along the pilot's line of sight.
