• Abstract:
  Two experiments involving the coding of Air Traffic Control messages for Digital Data Link transmission are reported. Reaction times and error rates to slide presentations were recorded for both experiments as a means for assessing the relative meaningfulness of messages. ; Experiment I studied the differences between long and short abbreviations with or without spaces. The need for the use of spaces was demonstrated. The experiment also indicated that with proper spacing, short and somewhat cryptic abbreviations were as useful as the longer and seemingly more meaningful abbreviations, even with only brief training of the experimental subjects. ; Experiment II provided a procedural variations using the same stimulus material as that reported in Section III of Report FAA-RD-72-150, with generally comparable results. It was determined that for short ATC messages differences in type font were not significant, that arrows were generally better than words for altitude and heading commands, that a format of three short lines was better than one extended line, and that "L" and "R" as heading commands in messages such as "HDGL23O" were extremely difficult to comprehend.
