16.3. TEXT
OFF THE GROUND: HOW DO WE FIND WHERE ARE WE GOING?
Scientists who are concerned with such a problem generally agree that birds
have some kinds of so-called «second sense» that allows them to fly over land and
water without getting lost. Indeed, birds are always able to find their destinations and
make a return fly without any trouble at all.
But people need help in finding their destination when piloting their own
airplanes. This, of course, is called destination.
Navigation is the art of finding your way from where you start your
destination. Whether used by the seamen, explorers or the pilots navigation falls into
three basic categories: dead reckoning which is the basis for all navigation, celestial
navigation which is flying by the aid of the sun and stars, and radio and radar
navigation.
Several different kinds of aeronautical maps provide all the details which might
be needed by the pilot. And hundreds of radio navigation stations are located at
different places around the world to help guide the pilot. All the pilot needs to do is to
tune to these radio transmitters and will get the directional signals he needs. Distance
