Core Viewpoint - The implementation of the "Red-Blue" aircraft pushback service model at Shijiazhuang Zhengding International Airport aims to optimize flight support processes, enhance ramp operation efficiency, and improve safety levels in response to increasing air traffic and flight operations [1][2]. Group 1 - The "Red-Blue" service model introduces a visual and standardized management approach by marking pushback directions with red and blue arrows, which helps to reduce ground waiting times and improve flight punctuality [1][2]. - The airport conducted extensive research on advanced airport management practices and tailored the model to its operational characteristics, ensuring effective communication and reducing operational errors [1][2]. Group 2 - The pilot implementation of the "Red-Blue" model began in March 2025 at designated parking positions, with the operations control center meticulously recording and analyzing performance data [2]. - Initial statistics indicate a significant reduction in average waiting times from the issuance of pushback commands to the actual pushback of aircraft, leading to improved efficiency during peak flight periods [2]. - The model enhances the standardization and safety of operations, clarifying responsibilities and streamlining processes for more reliable ground support [2].
