What does an unplanned 25 degree change in attitude by TMA do to
the CMGs? Would they be saturated?



The angle of the change isn't relevant (as long as the GNC Mode is
CMGTA). The rate is significant - because the CMG system is told to
not provide more than 200 ft-lb of torque. As long as the required
torque is less than that, normal desaturations will prevent
desaturation.
