TELECOMS POWER GLOBAL AIR TRAFFIC CONTROL
Telecommunications enable the movement of passengers and aircraft worldwide. Air Traffic Control uses VHF radio to communicate directly with pilots, while controllers rely on HF radio or satellite communication( SATCOM) for long-range contact over oceans and other areas. Radar and ADS-B systems transmit aircraft position and related data for surveillance. Controllers and pilots are increasingly using digital tools, such as CPDLC( Controller-Pilot Data Link Communications), to exchange text-based messages and clearances, thereby complementing voice radio and improving operational efficiency.
