This article focuses on a major human factors–related issue that includes the undeniable role of cultural factors and cockpit automation and their serious impact on flight crew performance, communication, and aviation safety. The report concentrates on the flight crew performance of the Boeing 777–Asiana Airlines Flight 214 accident, by exploring issues concerning mode confusion and autothrottle systems. It also further reviews the vital role of cultural factors in aviation safety and provides a brief overview of past, related accidents. Automation progressions have been created in an attempt to design an error-free flight deck. However, to do that, the pilot must still thoroughly understand every component of the flight deck – most importantly, the automation. Otherwise, if pilots are not completely competent in terms of their automation, the slightest errors can lead to fatal accidents. As seen in the case of Asiana Flight 214, even though engineering designs and pilot training have greatly evolved over the years, there are many cultural, design, and communication factors that affect pilot performance. It is concluded that aviation systems designers, in cooperation with pilots and regulatory bodies, should lead the strategic effort of systematically addressing the serious issues of cockpit automation, human factors, and cultural issues, including their interactions, which will certainly lead to better solutions for safer flights.

Integrated Team

The tremendous expense and inherent dangers of training in the aircraft have led to the increased use of simulators for practicing and maintaining air combat skills; However, the advantages and disadvantages of using high or low-fidelity simulators for such training must be specified. An experiment was conducted to examine the in-simulator performance differences between pilots flying lower-fidelity simulators compared to higher-fidelity simulators. The primary difference between the two simulators is the visual scene field-of-view. Sixteen U.S. Air Force F-16 pilots flew standard training missions as an integrated team of four (a “four-ship”) with two pilots flying in the high-fidelity simulators and two pilots flying in the lower-fidelity simulators. Various subjective and objective measures were collected to assess the pilots' ability to maintain a briefed formation. Overall, the results suggest that pilots who practice four-ship employment in the lower-fidelity simulators can perform at the same level as those who practice in the high-fidelity simulators. Future analyses should be conducted to examine the impact of simulator fidelity on other air combat skills and on training effectiveness.

The Impact

An experiment investigated the impact of normobaric hypoxia induction on aircraft pilot performance to specifically evaluate the use of hypoxia as a method to induce mild cognitive impairment to explore human-autonomous systems integration opportunities. Results of this exploratory study show that the effect of 15,000 feet simulated altitude did not induce cognitive deficits as indicated by performance on written, computer-based, or simulated flight tasks. However, the subjective data demonstrated increased effort by the human test subject pilots to maintain equivalent performance in a flight simulation task. This study represents current research intended to add to the current knowledge of performance decrement and pilot workload assessment to improve automation support and increase aviation safety.

Two studies were designed to investigate how pilots of different rank evaluate flight-deck performance. In each study, the pilots were asked to assess sets of three different videotaped scenarios featuring pilots in a simulator exhibiting poor, average, and good performance. Study 1, which included 92 airline pilots of differing rank, was aimed at comparing how individuals rate performance. The subjects used a standardized assessment form, which included six criteria, each having a 5-point rating scale. Analysis of the first study revealed that there was considerable variance in the performance ratings between flight examiners, captains, and first officers. The second study was designed to better understand the variance. Eighteen pilots (six flight examiners, six captains, and six first officers) working in pairs evaluated performances, in a modified think-aloud protocol. The results showed that there were good reasons for the observed variances. The results are discussed in relation to inter-rater reliability.

The Impact

Purpose of the research: Special product displays are expected to increase sales of the products they contain. Opposite to the rich existing literature on the impact of product in-store displays, we investigate the case of total product relocation instead of using the display location as an additional sales spot (secondary location strategy). Design/methodology: In our setting, products are fully taken off the usual shelf and put into special displays close to the checkout area. We use data from a field experiment conducted in 214 stores of a German perfumery chain, in which eight products were moved to an in-store display. Results/findings: Compared to the control group, the treated products placed in display boxes show a statistically significant increase in sales. The precise effect differs markedly between the investigated products, ranging from 80% to 478%. Accumulated sales increased by 217.69€ per week on average due to the installation of product displays. We can conclude that complete relocation, indeed, boosts sales, but the precise magnitude seems to be driven by factors not covered in this study. Practical implications and Conclusions: Based on the product selection, the results seem transferable to both other perfumery stores as well as general supermarkets. However, given the low additional revenues, retailers must consider all the additional costs associated with the implementation of product displays such as the costs of installing and maintaining the display, the costs of removing tags and rearranging the former shelf, and any opportunity costs. If these costs do not exceed the estimated effect, then the installation could be of economic importance.

The Impact

The purpose of this study was to investigate the use of EEG and cognitive functioning assessments to identify hypoxia in naval aviators. Naval aviators were brought slowly to a 6,096 m exposure to induce normobaric hypoxia while completing a cognitive assessment and a simulated flight task. There were significant reductions in cognitive performance at 6,096 m when compared to sea level. There were no significant changes in EEG-recorded brainwave activity during the 6,096 m exposure compared to sea level. There were also no significant decrements in flight performance at 6,096 m. Additional research is needed to better understand the impact of hypoxia on brainwave activity and pilot performance.
