The Max8 MCAS debacle has exposed inadequacies in the certification standards. The NG is different to the Classics, however the MCAS shows that if the aircraft encounters conditions that place it out of trim substantially, then handling that is not being trained, and airspace etc is needed in order to recover. The NG/Max has a greater potential problem due the the design change from the Classic, but none of these aircraft, and likely many other Part 25 aircraft can enter conditions that unloading of the stab could be required, the certification standard does not give protection from all possible conditions, just the level as specified.
