Disclosed is a visual tool for determining the spatial orientation of an aircraft relative to a level plane, including a closed container constructed of a material that permits the passage of light therethrough. An indicator body is fixed within the container and viewable through the container. An indicator fluid is provided including a liquid that fills the container a selected amount. The indicator fluid presents a fluid surface that is viewable through the container and free to move within the container. When the visual tool is affixed to an aircraft the indicator body and the fluid surface are parallel to the level plane when the aircraft is level. The indicator body is moved out of the level plane and the fluid surface remains parallel to the level plane when the aircraft deviates from the level plane to generate a visual signal representative of the orientation of the aircraft.
