With the constant technological advance in the aeronautical industry, the different communication processes have evolved over time. However, the importance of proper communication between the different actors in air operations remains one of the most important pillars of safety. Aeronautical Communications proposes that all pilots and air operators, regardless of their area of work, carry out communication processes in a standard way according to the requirements of ICAO (international civil aviation organization), but explained and analyzed by airline pilots with vast experience in the air. A theoretical and practical manual that will guide the reader towards the understanding of a communication process and its adaptation to the aeronautical industry, with all the appropriate technicalities and a standard phraseology used worldwide.
