Abstract
In heavy-cargo operations, lateral imbalance is a silent threat to flight efficiency. This methodology introduces a proactive simulation framework designed to identify and prevent “non-viable” loading states before the process even begins. It specifically targets the complexity of empty positions, leading to scenarios where asymmetrical cargo locking or mechanical failures prevent balanced loading across the aircraft’s roll axis.
The method, based on a published patent (ref [1]), allows the user to explore specific cargo layouts with stochastic weight distributions. The system executes multiple simulations to project the accumulated lateral moment. This allows the method to assess flight feasibility against given limit conditions, even when exact individual weights are unknown a priori.
Key Technical Advantages:
- Preventive Risk Mitigation: It establishes a clear “Viable/Non-Viable” binary before any physical loading occurs, preventing potentially inconvenient roll-axis
moments. - Stochastic Modeling: Uses input probability functions to account for weight uncertainty, ensuring efficiency in real-world conditions where load data is often
uncertain. - Asymmetrical Failure Analysis: Specifically models the impact of “locked” or disabled cargo locations, turning a complex mechanical limitation into a predictable data point.
This method transforms aircraft loading from a manual estimation task into a data-driven protocol, ensuring that no freighter departs with a lateral moment profile that is not convenient for the airline.
