How do planes communicate with each other?

Planes use several methods to communicate with each other during flight. The primary mode of communication is through the use of radio transmissions. Pilots and air traffic controllers communicate with each other over dedicated radio frequencies using standard phraseology.

Each country has their own radio frequency bands dedicated to aviation communications, and they are regulated by the International Civil Aviation Organization (ICAO). Pilots are required to hold a license and must demonstrate proficiency in radio communications in order to operate an aircraft.

In addition to radio transmissions, some planes are also equipped with technology that allows for the exchange of information via data links. These data links use a variety of methods to transmit information between planes and ground stations, including satellite and radio communications.

Overall, the communication methods used by planes are designed to ensure the safe and efficient operation of the aircraft, and to maintain situational awareness for pilots and air traffic controllers.
