Abstract: An aircraft weight and balance system includes a user interface that displays an interior layout of an aircraft with seat icons and cargo icons corresponding to seats and cargo zones onboard the aircraft. The seat and cargo icons are moveable to different locations within the interior layout, and an updated weight and center-of-gravity of the aircraft is automatically determined based on the different locations of the seat and cargo icons. An aircraft weight and balance method includes displaying an interior layout of an aircraft on a user interface including seat icons corresponding to seats onboard the aircraft, moving one or more of the seat icons to a different location within the interior layout based on a user input, determining an updated weight and center-of-gravity of the aircraft based on a current location of the seat icons, and displaying the updated weight and center-of-gravity of the aircraft on the user interface.

Abstract: The invention is an application method that applies fungicides, pesticides and other biocides to tree wounds by means of a dry process to prevent tree wound diseases and facilitate healing. The invention works with the first step of tree's natural healing process; the drying of the exposed wood surface. The biocides are applied dry or in a liquid formulation that dries quickly thus allowing the wood to dry quickly. The biocides, thus applied, do not interfere with the natural drying process and add additional biocidal protection. The biocides, thus applied, decrease infection and enhance the tree's ability to heal itself.
