Development of Integrated Display Reversion Design for the Next Generation Civil Aircraft

Advancements in technology have enabled the development of more integrated flight deck display formats, which are expected to enhance aircraft design and operational safety. The authors proposed a novel integrated display format for next-generation regional jets in previous research, aiming to improve situational awareness, reduce pilot workload during flight tasks. However, the research did not address display reversion necessary instruments to the remaining operational displays in the event of random display unit failures. Display reversion mechanisms must be carefully designed for the limited display areas available on regional jets, which are smaller than those of larger transport aircraft. Without appropriate reversion, it may become impossible to secure the MFW capacity strongly required for future aircraft, adversely affecting operations during display malfunctions. Conversely, an overemphasis on maintaining MFW availability could compromise other critical aspects of flight deck operation. To address this challenge, this study employs a measure framework to establish robust display reversion requirements and proposes its adequate design for the novel integrated display format in next generation aircraft. The proposed design prioritizes simplicity, minimizes role-switching between Pilot Flying (PF) and Pilot Monitoring (PM), and ensures the availability of MFWs for each pilot. The evaluation demonstrates that the proposed display format not only outperforms conventional designs by enhancing safety in current operations but also supports the transition to future single-pilot operations, even under display failure conditions. The proposed requirements and its evaluation process can be utilized for the other display format in the next generation civil aircraft as a framework.
