Measuring between a control input and the first response to instruments, visual, or motion base. FAA Advisory Circular AC 120-40B, for Aiplane Simulator Qualification says: "Relative responses of the motion system, visual system, and cockpit instruments shall be coupled closely to provide integrated sensory cues 6 These systems shall respond to abrupt pitch, roll and yaw inputs at the pilot's position within 150/300 milliseconds of the time, but not before the time, when the airplane would respond under the same conditions. Visual scene changes from steady state disturbance shall occur within the system dynamic response limit of 150/300 milliseconds but not before the resultant motion onset. [Note: 300 msec for Level A and B, 150 msec for level C and D] FAA AC 120-45A, for Flight Training Devices, requires 150 msec for level 7, and 300 for levels 1 through 6. Military standards are usually 150 msec, sometimes lowered to 100 msec. There is also a requirement that the three outputs be within 50 msecs of each other, and visual can't respond before the motion.
