When finishing spraying the area, to make another area using the same method, tap the Next Area button on the screen. 13 MAIN DISPLAY After an area is made, Guia Lite enters the Spray mode showing the guidance for pilot to spray the area. 1. XT Bar: Shown at the top of the screen. The full bar on the screen equals 10 LEDs on the lightbar. 2. Compass: Red needle pointing true North. 3. Tank Gauge: Material remaining in tank 4. Flight Lines: Shown as the row of numbers at the bottom of screen. The line locked for guidance is shown with white number. The lines already sprayed are marked in green 5. A/C Heading indicator relative to the AB line heading. It s pointing up when a/c flying parallel to the AB line, or AOI = 0. 6. The green T with a dashed line under a/c icon indicates spray on. 7. The information on the sides is determined by Settings Display. within 1.2 swath width, and red when XT greater than 1.2 swath width. When the a/c is outside the spray area indicated by length of the AB line, 2 red arrows are plotted at the top of the screen. If they point down, the area is behind you. If they point up, the area is ahead of you. If spray is stopped in the middle of the locked line, Guia Lite will remember the stop location. When flying back to the field to resume spraying the same line, a time countdown will appear on screen. Once the countdown hits 0, you are at the point where spray was last stopped on the locked line. In this picture, the a/c icon is plotted at the middle of screen. The thick vertical white line indicates the XT or distance from a/c to the locked line. The line is white when the XT is 14
6. FLYING OLD AREA new area created after 10 areas have been saved, the oldest area will be removed.
