Abstract:As new flight deck automation is introduced, there is interest in considering whether unintended uses of such new flight deck automation could affect the safety of operations in the NextGen NAS. The study team collected 24 examples of present day unintended uses from 22 current and retired commercial airline pilots, and identified the systems associated with each example (e.g. FMS, radio altimeter, etc.). These examples were examined to identify attributes that might allow pilots to use these systems in ways other than intended by their designers, and other than as approved by the FAA Aircraft Certification Service, and the FAA Flight Standards Service. Focus group comments revealed many unintended uses in operations where pilots use existing flight deck automation. Comments were grouped into categories, including: Over-Reliance on Automation and Complacency; Strategic Behavior – Gaming the System; Emboldened Behavior; ADS-B CDTI Uses; Unintended Use of the FMS; and Potential Processes To Discover Unintended Uses. The human factors analysis also identified the potential for how these unintended uses could have adverse safety consequences.
