Abstract:
1. A method to control the movements of a flight simulator motion system having a pilot's seat and at least two degrees of freedom, the at least two degrees of freedom including a lateral position (y) and a roll angle (φ), wherein the control of the movements involves linear and angular accelerations perceivable by a pilot seated at the pilot's seat, wherein roll rate (p) and yaw rate (r), as well as a specific force in a lateral direction (A y ) calculated according to a model of a simulated aircraft in a fixed point of the simulated aircraft are converted by a motion program to the lateral position (y) and the roll angle (φ) of the simulator, and wherein the method comprises the step of: calculating the roll angle (φ) of the simulator due to simulated aircraft roll angle by correcting an originally calculated value (φ wherein calculating the roll angle (φ where φ-hp equals high pass filtered simulator roll angle, ÿ-roll equals lateral position acceleration of the pilots' reference point P, being the result of multiplying φ-hp with a gain Ky and g and then high pass filtering, g is the earth gravity constant, Ky is a gain lateral co-ordination factor, φ-roll equals the simulator roll angle as a result of simulated aircraft roll acceleration or roll rate.
