Therefore, as with civilian planes there is usually no "plan B" (exception https://en.wikipedia.org/wiki/Cirrus_Airframe_Parachute_System https://en.wikipedia.org/wiki/Cirrus_Airframe_Parachute_Syst... ), acceptance criteria for unstable civilian aircrafts must be more strict than for military aircrafts. E.g. higher redundancy of HW & SW, stricter testing/checks/validation of flight envelopes, more feedback to the pilots about why a computer is performing certain actions, etc... than military aircrafts using the same systems.
