The NTSB wants the FAA to redesign the minimum safe altitude warning and conflict-alert systems to ensure they reliably capture and direct controller attention to potentially hazardous situations. Software changes should be implemented at all ATC facilities providing those services. Modifications also are needed to minimize false alarms. The FAA should also review the systems that are in place to verify that software configuration and parameters are consistent with local air traffic procedures, and that the warnings are provided to the relevant controllers. More training for controllers is also needed, the NTSB said.
