Misunderstanding:For example, a person might have und Fault. Any of these faults may be either a fail-silent failure (also known as fail-stop) or a Byzantine failure. Some may consider ‘error’ to be much more severe than ‘mistake’. Failures are most commonly used as opposite to successes. This is the main difference between fault and failure. The word fault itself refers to a mistake caused due to forgetting or misjudging a situation. Key Difference: Fault is most commonly used in terms of a mistake or an error done by a person. Dielectric Failure; Note: If you are using a CH2 tester, high voltage errors will be reported under different names (DW Arc Error, DW Current High Error, IR Has Leakage Error, etc). This is one crude example of fault tolerance, since either the ailerons or the rudder can fail and you are still able to make a turn (other effects of the failure, or other effects from the cause of the failure, notwithstanding).
