Safety recommendation A-06-44 through -47

Keywords: Air safety, Aerospace industry

The National Transportation Safety Board recommends that the Federal Aviation Administration:

^.Redesign the minimum safe altitude warning (MSAW) and conflict alert systems and alerting methods such that they reliably capture and direct controller attention to potentially hazardous situations detected by the systems. Implement software changes at all air traffic control facilities providing MSAW and conflict alert services (A-06-44).

^.Implement any software and adaptation modifications needed to minimise or eliminate unwarranted minimum safe altitude warning alerts (A-06-45).

^.Perform a technical and procedural review at all air traffic facilities with MSAW or conflict alert capability to verify that software configuration and parameters are consistent with local air traffic procedures. Ensure that MSAW and conflict alert warnings are provided to the relevant controllers (A-06-46).

^.Amend FAA Order 3120.4L, “Air Traffic Technical Training,” to require that all controllers study and demonstrate an understanding of the relationship between charted minimum instrument flight rules altitudes and the underlying topography for their areas. Emphasise that controllers should maintain awareness of aircraft altitudes to detect and effectively react to situations in which a safety alert may prevent an accident (especially aircraft operating in remote areas at night) (A-06-47).
