Will turbulence result in low-G condition for R22 ?

The low-G is unlikely to be too much of a problem in turbulence, because the low-G condition produced by turbulence is not usually sustained long enough for a roll to develop.

If a pilot’s reaction on encountering turbulence is to lower the collective and slow down, which will reduce tail rotor thrust and therefore remove most of the cause of the rolling tendency.
