Abstract : The report contains analyses of voice communications between aircraft and controller, with the objective of describing the overall patterns of these transactions. In particular, the distributions of message element frequencies and transmission times are examined. Comparisons between ground-initiated and pilot-initiated transmissions show little differences in the distributions. However, there are considerable differences when the data are broken down into messages made during first, last and other communication transactions. Distributions of operational characteristics (i.e. request, acknowledgment, etc.) also differ between ground- and pilot-initiated transmissions. Detailed dictionaries of the different message combinations appearing as transmissions are given in the second part of the report. (Author)
