Summary
This study investigates how air transport flight crews react to weather displays during simulated flight, addressing the challenge of integrating multiple weather information sources without increasing cognitive workload or reducing situation awareness. The research was motivated by the increasing complexity of modern cockpit displays, particularly the potential for conflicting representations between onboard radar and ground-based Next Generation Radar (NEXRAD). Previous studies were deemed insufficient because they lacked realistic experimental tasks, participants, and stimuli that approximated the complexity of modern weather displays. The primary goal was to examine how agreement between onboard and NEXRAD displays, distance to weather events, and the pilot flying influence flight crew deviation decisions, perceived workload, and situation awareness. The experimental design involved fifteen pilot-copilot teams who flew a simulated route while reacting to weather events presented in two graphical formats on a separate visual display. The study measured both performance-based outcomes, such as deviation decision accuracy, and judgment-based metrics, including perceived decision confidence, workload, situation awareness, and trust in the displays. The researchers specifically analyzed how crews handled discrepancies between the two radar systems and how their communication and leadership styles affected their responses to ambiguous weather data. The results indicated that pilots generally adopted a conservative reaction strategy, frequently choosing to deviate from weather rather than fly through it. When onboard and NEXRAD displays provided conflicting information, flight crews exhibited complex reactions: they tended to trust the onboard system more for immediate decision-making but utilized the NEXRAD system to augment their overall situation awareness. Additionally, the distance to the weather event significantly impacted crew performance; greater distance reduced situation awareness and heightened workload levels. In terms of team dynamics, flight crews predominantly adopted a participative leadership style characterized by open communication, rather than an autocratic approach. These findings suggest that future weather display designs should leverage the strengths of both systems. Specifically, designers should exploit the benefits of NEXRAD presentation for enhancing situation awareness while retaining the display structure and logic inherent in the onboard system to maintain pilot trust. The study highlights the importance of considering team dynamics and communication styles in display design, as participative leadership appears effective in managing the ambiguity and uncertainty associated with conflicting weather data. By understanding how pilots integrate and trust different information sources, designers can create displays that minimize visual clutter and cognitive burden, thereby improving decision quality and flight safety.
Key finding
Flight crews adopted a conservative deviation strategy and relied more on onboard systems for trust while using NEXRAD for situation awareness, particularly when display sources conflicted.
