Inspection Performance

The human inspector performing visual inspection of an aircraft is the backbone of the aircraft inspection process, a vital element in assuring safety and reliability of an air transportation system. Training is an effective strategy for improving their inspection performance. A drawback of present-day on-the-job (OJT) training provided to aircraft inspectors is the limited exposure to different defect types. Previous studies have shown offline feedback training using virtual reality (VR) simulators to be effective in improving visual inspection performance. This research aims at combining the advantages of VR technology that includes exposure to a wide variety of defects and the one-on-one tutoring approach of OJT by implementing a collaborative virtual training environment. In an immersive collaborative virtual environment (CVE), avatars are used to represent the co-participants. In a CVE, information of where the trainer is pointing can be provided to a trainee as visual deictic reference (VDR). This study evaluates the effectiveness of simulating on-the-job training in a CVE for aircraft inspection training, providing VDR slaved to a 3D mouse used by the trainer for pointing. The results of this study show that the training was effective in improving inspection performance.

Inspection Performance

Training has been a consistently effective intervention in improving inspection performance. For example, existing inspection training in the aircraft maintenance domain is mainly a combination of classroom and on-the-job training (OJT). Computer-based training (CBT) has been promoted ever since it was introduced to this domain. In this study we investigate how effectively feedback training can be combined with CBT to improve visual inspection performance. Specifically, we examine the potential positive impacts of performance and process feedback in CBT, given in an on-line manner, on a trainee's performance and process assessment in a visual inspection task. The CBT system for inspection we used was adopted from the ASSIST program (Chen, Gramopadhye and Melloy, 2000). In our computer simulation of a familiar situation, participants were asked to search certain areas inside of a car in order to detect certain targets (dropped coins) with the aid of computerized tools (e.g., a magnifying glass, a flashlight), and fill out an inspection report based upon detection. A significant test effect was found across performance measures. Type of feedback training was found to be significant for search time. Performance measures were significantly correlated with target difficulty level; on-line performance feedback was significantly more efficient in improving performance measures than conventional delayed performance feedback; feedback training did affect process assessment measures.

Inspection Performance

Thirty-nine subjects participated in an experiment designed to evaluate the influence of the reflective-impulsive cognitive style on visual inspection. The Matching Familiar Figures Test (MFFT) was used to classify subjects as reflectives (longer times, fewer errors), impulsives (shorter times, more errors), fast-accurates (shorter times, fewer errors), and slow-inaccurates (longer times, more errors). Following administration of the MFFT, subjects participated in a laboratory visual inspection task. Results from the inspection task indicate that the MFFT groups coalesced along an accuracy rather than a speed dimension. The more accurate groups (reflectives and fast-accurates) were significantly faster than the inaccurates (impulsives and slow-inaccurates) in detecting certain flaws, and they made fewer size-judgment errors. However, the inaccurates detected more flaws, (i.e., made fewer search errors) than did the accurates. These results are interpreted in terms of the possible cognitive styles affecting inspection performance.
