Errors

Error: means an action or inaction by the flight crew that leads to a variance from operational or flight crew intentions or expectations.

Minor Error

An action or inaction that is inconsequential to the completion of a task, procedure or manoeuvre, even if certain elements of the performance vary from the recommended best practices.

Major Error

An action or inaction that can lead to an undesired aircraft state or a reduced safety margin, if improperly managed; or an error that does not lead to a safety risk, but detracts measurably from the successfulachievement of the defined aim of a sequence/item.

Critical Error

An action or inaction that is mismanaged and consequently leads to an undesired aircraft state or compromises safety such as:

  • non-compliance with CARS or non-adherence to mandated standard operating procedures (SOP); or
     
  • repeated improper error management or uncorrected and unrecognized threats, which risk putting the aircraft in an undesired state; or
     
  • repeated major errors or the non-performance of certain criteria prescribed in the Performance Criteria* that are essential to achieving the Aim* of a test sequence/item.

* defined in the Flight Test Guide.
