As the aircraft reaches the edge of the page, the map automatically redraws itself with the map center
being determined by the last aircraft position (if auto centering is on).
Select the desired Mapping Control buttons at the right of the area map to adjust the map scale, select a
different map, alter the number of nav symbols displayed, adjust the latitude or longitude, clear the aircraft
track, or change the map display. Refer to paragraph 3.10.1., MAPPING CONTROLS.
