SC-231, Terrain Awareness Warning Systems (TAWS), established March18, 2014, is working to develop an industry consensus set of TAWS (Terrain Awareness Warning System) standards reflecting the mature nature of this technology and incorporating enhanced requirements and new capabilities. The new MOPS will also incorporate the revised GPWS requirements (from DO-161A) and will be useful to designers, equipment manufacturers, aircraft manufacturers, airlines, and aircraft operators, installers, and aviation authorities. The new MOPS for TAWS will provide the foundation for the revision to Technical Standard Orders (TSOs), TSO-C151c.

DO-367 was approved by the PMC and is available in our store, The committee will be sunset after the revised TSO is released in the fall of 2017.
