[SV650rules]

Problem seems to be ( and anyone who watches air crash investigation documentaries will know this ) that modern pilots are reduced to computer minders, and if the auto systems turn off ( which they will do if they detect a sensor malfunctioning ) many do not know how to fly the plane, and sometimes the controls will not let them do certain things.

Seems in the Ethiopia crash something hit the anti stall sensor ( uses a pivoted vane to detect airflow over aircraft I believe ) and damaged it so auto system turned off, after that it was a fight between pilots trying to climb the plane and the stability control trying to get the nose down, and because of lack of altitude ( altitude is your friend if the plane has a problem ) they lost the battle with planes systems.
