Chapter5 Information Systems Introduction This chapter introduces information systems available in  the advanced avionics cockpit. These systems support you  in following flight progress, and in avoiding terrain, traffic,  and weather hazards en route. A moving map continuously  displays the aircraft’s position relative to the intended route  of flight, and helps you maintain the “big picture” (situational  awareness) as your flight progresses. A Terrain Awareness  and Warning System (TAWS) color codes surrounding  terrain to make it easily apparent when terrain poses a  threat. Weather systems provide in-flight access to many of  the same weather products available on the ground. A fuel  management system makes predictions about fuel remaining  at each waypoint along the route, and helps monitor actual  fuel use as your flight progresses.
