About this app
Pilots and air traffic controllers communicate by using the radiotelephony phraseology that consists of a set of standardized words and phrases approved for the radiotelephony communications by ICAO in all routine aircraft situations. The communication is made possible due to their common and work-related topics, especially because the situations they find themselves in are highly predictable. Even if misunderstandings do occur, they are rather easily dealt with since both parties engaged in the conversation know what replies to expect from each other. Problems arise in non-routine and emergency situations, when pilots and controllers have to resort to plain English because the phraseology lacks the communicative means for effective communication in unpredictable situations such as on board medical emergencies, engine problems, fuel shortage or terrorism. When both parties stick to the rules prescribed, problems in communication will rarely occur. First of all, good transmitting technique is needed. In this traning you will learn basic steps of efficient communication with Air Traffic Controllers.
