Radiotelephone communications lack the facial cues, body language, and listening cues found in usual faceto- face situations. Communications without such cues are considered to be more difficult and challenging, requiring a higher degree of language proficiency, than face-to-face interactions. In addition, other features of radiotelephone communications make it a unique kind of communicative event, for example:

- The sound quality may be poor, with distracting sounds.

- The communicative workload of the air traffic controller or a pilot may be heavy, with a corresponding need for efficiency and brevity.

- In addition to their communicative tasks, pilots must also attend to all of the tasks involved in operating their aircraft.
