Isaac Arthur Gennissen will give a presentation on his master thesis, entitled:

Roll-Sway Motion Cueing for Transport Aircraft


The simulation of roll rates causes noticeable false g-tilt cues as a result of the simulator cabin roll angle. The false tilt is counteracted by swaying the simulator cabin, however, improper implementation of the motion drive logic for coordinating sway could cause delayed side-forces. The aim of this paper is to evaluate two methods of driving the coordinating sway, the classical washout filter and the ‘coordination algorithm’, and compare those with uncoordinated motion. An experiment was conducted in which 14 experienced pilots performed side-step manoeuvres in a large generic transport. Six motion drive configurations were compared: no-motion, rotations only, coordinated rotations only for the two motion drive logics and full motion for both motion drive logics. The results showed unaffected performance, but subjective motion fidelity ratings show that pilots prefer the uncoordinated rotations-only condition, suggesting that the current methods for simulation of coordinated turns can be improved upon. Static simulations result in the highest rotational accelerations, which shows that pilot control behaviour is affected by the presence of motion; pilots steer less acute when motion is turned on. The results suggest that the industry standard, the University of Toronto Classical Washout filter, can be improved by adjusting the method for driving the coordinating sway motion.
