This research focused on identifying communication strategies and procedures related to efficient and error-resistant data link communication. A coding scheme was developed that identified five steps in the data link communication cycle in which information may need to be transmitted between operators. This methodology was applied to a data link full mission study with 10 flight crews as participants. Initial results indicated that the amount of information transferred may impact communication timing and efficiency. The impact of data link upon the roles and procedures of the crewmembers is discussed.
