In one example methodology, a simulator transitions its rate of rotation to replicate flight conditions in which G-forces are unloaded on a trainee from a first-G-force value to a nominal-G-force value.

This intermediate-G-force value may be determined based on several factors including: (i) the angle of rotation of a gondola at during the first-G-force value, and/or (ii) the first-G-force value. After the intermediate-G-force value is imparted and maintained for a suitable duration of time, the G-forces imparted on the trainee may be further unloaded till the nominal-G force value is reached.
