Function: aircraft navigation: dead reckoning is a way of navigating when there are few or no visible landmarks. A pilot uses dead reckoning when flying over large bodies of water, forests, deserts, or heavy cloud layers. Besides an aeronautical chart, a pilot needs an accurate clock and compass and a small computer for figuring complicated mathematical problems. Working with the chart, the pilot plots (plans) a route in advance. The pilot also figures how long it should take to reach the destination while flying at a constant speed. With the help of the computer, the pilot adjusts the course to allow for the effect of the wind.
