Garmin GNC 420W Pilots Guide - Page 41

SECTION 3 NAV PAGES The 'Setup Map?' option (described in Section 3.4) allows the pilot to define the maximum range at which each map feature appears. This provides the pilot with complete control to minimize screen clutter. The pilot can also quickly remove items from the map using the CLR Key. Quickly decluttering the Map Display: Press the CLR Key momentarily (as needed) to select the desired amount of map detail. The CLR Key allows the pilot to quickly declutter the Map Display, providing four levels of map detail. Note the '-2' ('-1' and '-3' are also provided) suffix designation in Figure 3-10, indicating each successive declutter level. Map Panning Another Map Page function is panning, which allows the pilot to move the map beyond its current limits without adjusting the map range. When the panning function is selected (by pressing the small right knob), a target pointer flashes on the Map Display (Figure 3-11). A window also appears at the top of the Map Display showing the latitude/longitude position of the pointer, plus the bearing and distance to the pointer from the present position. Pointer Position Window Target Pointer Map Detail Level Figure 3-10 Detail Level on Map Page The right-hand side of the Map Page includes four user-selectable data fields (Figure 3-8). By default, the displayed data is: destination waypoint name (WPT), desired track (DTK), distance to destination waypoint (DIS), and ground speed (GS). Any of these data fields may be changed to display a different data type, as outlined in Section 3.4. The pilot may also remove the four data fields from the map to show a larger map image, as described in Section 3.4. Figure 3-11 Panning on Map Page Selecting and using the panning function to pan the Map Display: 1) Press the small right knob to activate the panning target pointer. 2) Turn the small right knob to move up (turn clockwise) or down (counterclockwise). 3) Turn the large right knob to move right (turn clockwise) or left (counterclockwise). 4) To cancel the panning function and return to the present position, press the small right knob. 190-00140-20 Rev.
