Error tolerance, which is an error management strategy, aims at making..
  • A
    it easy to rapidly recover the system to its safe state after an error has been committed.
  • B
    the system better able to sustain itself despite error, e.g. by minimising the consequences of errors.
  • C
    the system such that it minimises both the likelihood and the magnitude of the error.
  • D
    errors apparent as fast and as clearly as possible, thereby enabling recovery.

According to ICAO, Error management is the process of detecting and responding to errors with countermeasures that reduce or eliminate the consequences of errors and mitigate the probability of further errors or undesired states.

ERROR MANAGEMENT STRATEGIES

  • Error Prevention aims at avoiding the error completely.
  • Error Reduction aims at minimizing the likelihood that an error occurs and minimizing the extent of an error.
  • Error Detection aims at making errors apparent as fast and as clearly as possible, thereby enabling recovery.
  • Error Recovery aims at making it simple to rapidly recover the system to its safe state (after error occurrence).
  • Error Tolerance aims at making the system better able to sustain itself despite error, i.e. minimizing the consequences of errors.
