Any AP self-initiated disconnect due to turbulence alone, without w/o some other internal AP or servo failure happening, or some prior saturation indication, isn't good, ...particularly when coupled to an ILS or GLS. In fact for any FAIL OP Mode, that kind of AP anomaly behavior is inappropriate, and can be dangerous, if not even uncertificable, ....or if for a system already certificated, grounds for issuance of additional operating limitations, or even issuance of an AD until corrected, or otherwise use limited.
