Even after corrections, the program, called Minimum Safe Altitude Warning, has its flaws.

Minimum Safe Altitude Warning (MSAW)

The system, called Minimum Safe Altitude Warning, looks for planes that are too close to the ground or are likely to become too low in the next few minutes.

But Anchorage Center does not have Minimum Safe Altitude Warning (MSAW) equipment active for the Fairbanks Approach Control airspace.

An upgrade of the Approach Radar Display System at Fujairah International Airport will include Short Term Conflict Alert, and Minimum Safe Altitude Warning functionalities..

Maps of the area along with Mode C or S transponder elevations will allow Minimum Safe Altitude Warning (MSAW) systems to warn controllers of possible terrain conflicts.

Minimum Safe Altitude Warning (MSAW): a tool that alerts the controller if an aircraft appears to be flying too low to the ground or will impact terrain based on its current altitude and heading.

Despite the hilly terrain surrounding it, the approach to runway 28 was not equipped with a Minimum Safe Altitude Warning (MSAW) system, which triggers an alarm if a minimum safe altitude is violated.

Another anti-CFIT tool is the Minimum Safe Altitude Warning (MSAW) system which monitors the altitudes transmitted by aircraft transponders and compares that with the system's defined minimum safe altitudes for a given area.
