天府机场全面启用A3级毫米波门

Core Points - Chengdu Tianfu International Airport has upgraded all 58 units of millimeter-wave body imaging security check equipment to the latest A3 level standard, becoming the airport with the highest number and proportion of A3 level millimeter-wave gates in China, significantly enhancing the detection capability and accuracy for various prohibited items and alleviating the queuing phenomenon during peak passenger flow [1][2] Group 1 - The airport was the first in the country to implement large-scale use of millimeter-wave gates during its construction phase, which can detect metals, liquids, and explosives without physical contact, while also protecting passenger privacy [2] - The upgrade to A3 level millimeter-wave gates has eliminated blind spots for foot detection, achieving 100% metal detection for the feet, and improved overall equipment performance through algorithm optimization [2] - Since the implementation of A3 level gates, the foot recheck rate has decreased to 53.89%, the average personal inspection time has reduced from 25 seconds to 19 seconds, and the average release efficiency during peak hours has increased from 164 to 178 passengers, representing an efficiency improvement of approximately 8.5% [2] Group 2 - The airport plans to continue exploring "non-contact" security check models and aims to build a modern security system characterized by "zero tolerance for safety, warm service, and improved efficiency," contributing to the overall safety service level of the aviation industry [3]
