Abstract. A
Gibsland GA fixed wing aircraft equipped with a computer-controlled, variable
rate spraying system was field tested for automated on-off spray
capability. A rhodamine dye added to the
spray tank deposited over a one millimeter cotton string was used to detect the
commencement and cessation of application.
Field tests indicated that the automated spray system could cut on and
off to within fifty feet of the desired location. Variable rate aerial
application testing is underway and preliminary results of this research will
be presented.
