The centre of gravity (cg) of an aircraft is of fundamental importance to its stability, but it is difficult to measure precisely in-flight because it will vary as the aircraft manouevres and fuel is consumed and sloshes in its tanks. This paper describes the development of a longitudinal cg estimator using Kalman filters. Two examples are provided of the estimator. The first example uses a linear Phantom F4-C aircraft model in which an unexpected moment representing a cg change is injected into the aircraft and then estimated, and the second example uses a linearised version of a more comprehensive aircraft model, ADMIRE.
