The Load/Unload Monitoring System is a mobile operation management tool. On-site operators scan aircraft compartment codes and unit load device (ULD) codes, and the system automatically synchronizes with the load sheet data from the weight and balance system to realize intelligent matching and verification. It eliminates manual operational errors at the source and prevents incorrect, missing loading and unloading of cargo for flights, ensuring high accuracy of loading and unloading operations. Meanwhile, the system collects operational data in real time and visually presents the flight loading/unloading progress. Based on archived data, it calculates key indicators such as operation duration, providing solid data support for refined management and efficiency optimization of aviation loading and unloading work.
