{{linkless}{ Acceleration onset cueing is a term for the motion cueing principle used by a simulator motion platform. It works in three phases:

  1. The initial acceleration of the vehicle being simulated is replicated closely by the platform. However, the platform jacks cannot go on moving without reaching their "limit stops" and a technique is used that prevents the stops being reached without being discernible to the simulator crew.
  2. After the above initial acceleration, the jack movement is gradually decreased, eventually to zero (this is known as the washout phase).
  3. Finally, the motion platform is reset to the neutral position but at a rate below that of the sensory threshold of the simulator crew.

The human body motion sensors (inner ear, muscle-and-joint feedback, body movement) react to accelerations rather than steady-state motions and have thresholds below which they do not react. Thus, the way the body signals motion to the brain coincides very well with acceleration-onset cueing in a simulator. This is the reason why well-designed and properly set-up modern low-latency motion platforms in simulators work so well for all aircraft from large transports to agile fighters
