Safety and Human Factors Challenges of Aircraft Berths: Problem Analysis and Optimization Approaches

With the development of long-distance flight technology and the increasing demand for ultra-long-haul flights, ensuring passenger comfort and safety has become a critical challenge. Aircraft berth designs play a key role in addressing this issue. However, existing designs still exhibit limitations in safety, ergonomic adaptability, space utilization efficiency, and intelligence features. This study, through literature and case analysis, systematically examines the safety and human factors challenges in current aircraft berths, and examines the shortcomings of existing berth designs in collision protection, body support, spatial configuration, and intelligent integration. Based on the analysis, multi-dimensional optimization schemes are proposed to enhance berth safety, ergonomic adaptability, space utilization, and intelligent features. The findings contribute to the theoretical framework for intelligent cabin design, and explores innovative paths under the human-machine-environment model. This study provides insights for optimizing aircraft berth designs, ultimately improving passenger experience and safety in ultra-long-haul flights.
