What are examples of catastrophic failure in DO178B?

In the context of DO-178B, catastrophic failures are those that can lead to loss of life, significant injury, or extensive damage to the aircraft and its surroundings. Examples include software faults that cause an aircraft to stall or lose control during flight, erroneous navigation leading to terrain collisions, or incorrect functioning of critical systems like flight control or engine management. These failures emphasize the necessity for rigorous software verification and validation processes mandated by DO-178B to ensure the safety and reliability of airborne systems.
