Abstract: According to one embodiment of the disclosure, a method of determining a center of gravity of an aircraft includes receiving a strut length for each of the gears of an aircraft, determining an arm length for each of the gears, and determining a center of gravity of the aircraft based on a relationship between the center of gravity and respective arm lengths for each of the gears. The arm length of each of the gears is determined according to the strut length of a gear strut of a respective gear and a relationship between the strut length of the gear strut to another gear of another aircraft and the arm length of the respective gear.

Abstract: A dispenser providing access to a plurality of pre-moistened towelettes and having dual orifices covered by a self sealing lid. A larger recessed orifice in the top side of the container accommodates a smaller opening and both openings are covered by a lid attached to a ledge surrounding the larger recessed orifice perimeter. The lid has approximately the same planar dimensions as the combination planar dimensions of the recess and ledge and is held in a closed position by press fitting under an outer border curbing the perimeter of the outermost edge of the ledge. A removable back panel is provided for ease of refilling prepackaged towelettes in the dispenser, and a second back attachment means is provided for attaching or mounting the dispenser to a flat surface.
