ABSTRACT

The article discusses an environment and lifestyle impact on activities of air traffic controllers (ATC), the possibilities to observe their performance and focuses on their verbal expressions during work activities. The results of air traffic controllers’ verbal communication gained and evaluated, recorded in air traffic procedural and radar control training, point to a possible relationship between stress, fatigue, limited ability to perform a controlling activity on one side and verbal expression characterized by variations in the rate, volume, colour or delay responses to impulses on the other. The discovery of this dependence opens up the possibilities to look at a hypothetical solution of non-invasive, non-contact observing their skills and limitations in direct activities by monitoring their main working tool—own voice.
