As the nose is slowly pitched up the airspeed deceases slowly. If you fail to notice this, eventually the aircraft will get your attention with a sudden nose up pitch just before it falls out of the sky with zero airspeed. I've seen this happen during recurrent training, far too many times.
Is the behavior you describe specific to particular SPZ-7000 installations? The SPZ-7000 DAFCS Pilot's manual for the S76 says: "The go-around mode may be engaged by pressing the button on the mode selector or by depressing the go-around switch on the collective. When engaged this mode will cancel all other modes that are engaged. Upon engagement the collective will be commanded to obtain 75 knots or more while the roll axis will return the aircraft to a level roll attitude and will maintain the current aircraft magnetic heading. The pitch axis will be commanded to a positive rate-of-climb of 750 fpm."
