Three techniques of presenting troubleshooting information were experimentally evaluated using a paper and pencil test to simulate equipment characteristics. Ss were 222 AF basic trainees. The results indicate that procedural instructions are significantly more efficient (p < 0.001) than standard schematics or data flow diagrams in terms of troubleshooting time and accuracy. The interactive effects of circuit type and circuit complexity were determinates of troubleshooting problem difficulty. As circuit complexity increases, so also does the efficiency of procedural instructions relative to the efficiency of standard schematics and data flow diagrams.
