Description

MSAW (Minimum Safe Altitude Warning) warns the controller about increased risk of Controlled Flight Into Terrain (CFIT) accidents by generating, in a timely manner, an alert of aircraft proximity to terrain or obstacles.

Since 1998, EUROCONTROL has produced safety net guidelines to support the implementation of safety nets in the European Civil Aviation Conference (ECAC) area. These specify the minimum requirements and provide guidance for the definition, implementation, optimisation and operation of ground-based safety nets. This article provides references to EUROCONTROL Minimum Safe Altitude Warning (MSAW) Specification and Guidance Material. Links to the articles about the other safety nets can be found at the bottom of this page.
