measuring equipment now used in many airplanes tells the pilot exactly how far he is
from a radio station and what speed he is traveling over the ground.
When certain types of weather prevent the pilot from seeing the ground,
additional radio transmitters let him make his approach to an airport by simply
watching his flight instruments and radio receiver indicators. These receivers help the
pilot descend on the runway, thus landing at an airport even though he cannot see the
ground.
At the world’s larger air terminals airplanes are provided with radar guidance
as another means of guiding the pilot to the destination. With the help of an electronic
transponder in each airplane which shows it in the radar screen, radar controllers
guide hundreds of airplanes to landing.
Because of the great improvement in electronic and radio navigation
equipment, flying to where you are going is done as efficiently as the birds do it and
much more scientifically.
