A self-report critical incident assessment tool for army night vision goggle helicopter operations

The present study sought to examine the utility of a self-report tool that was designed as a partial substitute for a face-to-face cognitive interview for critical incidents involving night vision goggles (NVGs).

The use of NVGs remains problematic within the military environment, as these devices have been identified as a factor in a significant proportion of aircraft accidents and incidents. The self-report tool was structured to identify some of the cognitive features of human performance that were associated with critical incidents involving NVGs. The tool incorporated a number of different levels of analysis, ranging from specific behavioral responses to broader cognitive constructs.

Reports were received from 30 active pilots within the Australian Army using the NVG Critical Incident Assessment Tool (NVGCIAT).

The results revealed a correspondence between specific types of NVG-related errors and elements of the Human Factors Analysis and Classification System (HFACS). In addition, uncertainty emerged as a significant factor associated with the critical incidents that were recalled by operators.

These results were broadly consistent with previous research and provide some support for the utility of subjective assessment tools as a means of extracting critical incident-related data when face-to-face cognitive interviews are not possible.

In some circumstances, the NVGCIAT might be regarded as a substitute cognitive interview protocol with some level of diagnosticity.
