Claim 8:
9. A method for determining loads acting on an aircraft, including:
detecting instantaneous first accelerations by a first inertial measurement device in the aircraft;
detecting instantaneous second accelerations by at least one second inertial measurement device in the aircraft, which is arranged at a distance from the first inertial measurement device;
determining loads acting on the aircraft by:
determining expected maneuver accelerations from the first accelerations and from position information provided by a control computer;
determining dynamic accelerations on the aircraft by filtering out the expected maneuver accelerations from a totality of the detected first accelerations and second accelerations;
determining expected maneuver loads from the expected maneuver accelerations by a maneuver load model;
determining dynamic loads on the aircraft from the induced dynamic accelerations; and
determining a sum of the expected maneuver loads and the dynamic loads as loads acting on the aircraft;

storing the loads acting on the aircraft in a memory unit or transferring the loads acting on the aircraft to an external unit; and
determining modal accelerations of the aircraft, which include rigid body modes and elastic modes of the aircraft, from the detected first accelerations and the detected second accelerations.
