In this paper, a novel model-based loads monitoring method is introduced, that allows for a high precision in the estimation of flight loads. The new method is based on the hybridization of two state-of-the-art loads estimators (a Luenberger observer and a local model network approach) and combines the individual advantages of the underlying methods. The hybrid method features an accurate estimation of structural loads due to manoeuvres and gusts even for high load events and can be set up for a given and suitable flight test database with low effort. Therefore, the hybrid method provides a cost-efficient set up of an accurate aircraft loads monitoring system. The paper focuses on the introduction of the hybrid method for loads estimation and its validation by means of an extensive flight test database containing high manoeuvre and gust load events, which has been acquired using the ultra-light test aircraft UW-9 Sprint.
