Pilots/Air Traffic Controllers Phraseology Study

150px-IATAphraseologystudyAs the world becomes more and more “global”, language becomes a key factor in the efficiency of Pilot – Air Traffic Control (ATC) communications. Language and communication issues are very important because a miscommunication could potentially lead to a dangerous situation without any of the involved stakeholders being aware.

The use of standardized phraseology is one of the most important factors involved in the process of communication. It provides for quick and effective communication allowing us to overcome differences in language and at the same time reducing the opportunity for misunderstanding. Ambiguous or non-standard phraseology is a frequent causal or contributory factor in aircraft accidents and incidents.

This report presents the results of an online survey regarding communication issues, focusing on the non-use of ICAO standard phraseology. Separate surveys for both airline Pilots and Air Traffic Controllers were prepared to collate the lessons learned in the area of communications.  

The survey questionnaires were prepared and set-up so that participants could easily respond via a survey engine website on the internet. The use of “Aviation English” was explicitly excluded from the report as this issue has been managed through other venues. The surveys were designed to identify areas where established phraseology, or local phraseology, has been, or has the potential, to be misunderstood.

The report of this survey is listed below:
