Nowadays flight load exceedance monitoring is an important task to the aircraft manufacturer as well as the operator. The estimation of flight loads is required during development and operation of an aircraft. The requirements are usually different for e.g. calculation of design loads for certification and operational loads monitoring of stress and fatigue. The ability to determine aircraft operational loads (more) precisely may reduce the time in maintenance and is an enabler for e.g. loads/fatigue monitoring at operator level. In this paper the system identification method of local model networks is applied to the field of flight loads estimation targeting on-board aircraft systems. The design and development process of a flight loads estimation algorithm based on design and flight test data is presented.
