Re the comments on whether Neg G is possible I think it is but it actually the inertia of the helicopter that causes it. Say for instance you are traveling at 60 knts in the climb at say a 30 degree from the horiz angle. Whilst lowering the lever to zero pitch and nosing the aircraft down the inertia of the aircraft has changed rapidly from the 30 degree up angle to the down path the aircraft is taking (this has to be a relatively severe
manoeuvre to create this). This will create the effect of negative g
Any comments ? or am I completely out the ball park ?
