Abstract
Disclosed is a method and device for estimating forces exerted on at least one aircraft control surface. The method includes steps of, and the device includes components that carry out steps that include: generating current aircraft flight data; determining, from the generated aircraft flight data, a value Bl based on current deflection data and geometrical characteristics of a lever arm actuator of the at least one aircraft control surface; calculating, from the determined value Bl, at least one hinge moment; summing each calculated hinge moment; and dividing the sum by the value Bl to obtain an estimate of the forces exerted on the least one aircraft control surface.
