Flight training simulators have a limited capability to replicate aircraft motion cues because the space envelope of current motion systems mpedes a better fidelity and urges the user to make sometimes painful ompromises. Therefore, it is all the more important to use the given space envelope as well as possible. But this trivial consideration yields an answer to the question what “good” means and therefore what strategy shall to be pursued by a control algorithm. For the Apparent Vertical Filter (AVF) this eans that the amount and direction of the force combined with the orresponding rotational velocity shall be met as long as the given space nvelope allows that approach. If this is not possible anymore the direction of the specific force shall be reproduced correctly. Only if both, the rotational and the translational cueing cannot be achieved a decision must be made. This is the case e.g. for the side force during a taxi turn on round. During such maneuvers a compromise needs to be found between a correct specific force and a limited rotational velocity of the simulator. Within this paper the working principle of the Apparent Vertical Filter will be discussed for a taxi turn on ground maneuver. Furthermore, it will give a eneral overview of the AVF response to lateral maneuvers in general. inally, it presents the results for the lateral tests of the Objective Motion Cueing Test (OMCT) showing that, in general, the AVF is able to meet the requirements of the test.
