About the course

5-day (40 hours) classroom course

IATA Aircraft Weights Engineering for DCSs: Trimsheet Design & X565 Data aviation training course

The course is designed to assist flight operations (performance) engineers who are responsible for the development of weight and balance limitations, as specified in the aircraft manufacturer’s certified weight and balance manual (WBM). The course provides an understanding of the techniques used to develop operational X565 (formerly AHM560/565) data for use in computerized load control systems (Departure Control Systems ) and for the design and creation of manual Load and Trimsheets. The course also covers recurring tasks such as the maintenance of aircraft weight history, the process of aircraft weighing including the calculation of the aircraft empty weight and center of gravity. Although the course includes an understanding of the end to end process of load planning and ramp operations, it is not intended to provide proficiency in the load controller role.
