The results of three experiments involving eight FAA NAFEC test pilots are reported. Section I describes the evaluation of four prototype Data Link displays in a GAT-1 simulator. While there was lack of agreement among the pilots as to the relative merits of the four displays, their opinions concerning Data Link as a concept were generally favorable. Section 2 describes reaction time and error rate measurements made as 144 slides were presented containing a variety of short ATC messages. It was determined that differences in type front were not significant, that arrows were generally better than words for altitude and heading commands, and the L or R as heading commands in messages such as HDGL230 were extremely difficult to comprehend. Section 3 describes a second laboratory experiment which studied the differences between long and short abbreviations with and without spaces. The need for the use of spaces was demonstrated.
