The pilot and people in land must have to register the exact time of the take off and according to that information the time of “fixed crossings” and landings was calculated. Little by little technological advances were adapted to the aeronautic media also some land/terrestrial aids were implemented such as the construction of “Radio Beacons” circa 1932, being this ones the predecessors of radio aids.Īir Traffic Control Services were born because of the increase number of airborne operations which made necessary to introduce/implement/create certain type of co-ordinate control. Lately the introduction of radiotelegraphy allowed pilot and people in land to communicate these last ones would send/transmit meteorological reports. The first aerial night route was implemented in 1921, when some “Radio Beacons” were installed between Columbus and Daytona, Ohio, USA they were visible to pilots, had a separation distance of 80nm and spun every 10 seconds. It became an important matter to count with reliable air transport, this is why on board certain instruments such as compass and coordinates were used, and also it became necessary to develop aids in land.
The result of these important changes was the creation of a new and peculiar activity: Air Traffic ControlĪviation pioneers used to fly just by looking through the horizon and make use of some land references and basically guided by their own senses, intuition and skills developed by their practice and strong desire to fly.
At the end of the ‘40s an important development in aviation took place, the number of aircraft and commercial flights were growing and as a consequence Air Navigation was born.
