The one publication I know of that included information on sloping terrain is
what N6BT wrote in NCJ. The graph at the end of the article came from a HOBBIES
simulation by KI6OK, showing that a vertical adjacent to sloping ground will
have the takeoff angle lowered a bit over 1 degrees for each degree of slope.
Tom also discusses pattern testing with drones on his shallow-slope property.
