VASI Improvements "T" VASI Evaluation

Task was to perform technical tests and evaluations of variations of the Standard "T" -VASI system to determine whether
such modifications would better suit the system for use within the U. S. National Airspace System (NAS). The" T" -VASI is a Visual Approach Slope Indicator System developed by the Australian Government to provide visual glide path guidance, under Visual Flight Rules (VFR) conditions, through a light display in the form of "T" ("Fly-Up") and inverted" T" ("Fly-Down") signals to indicate deviations from the desired glide path.
