Abstract

The Ground Proximity Warning System (GPWS) and Terrain Awareness Warning System (TAWS), developed at the Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, is currently fielded on the F/A-18A/B/C/D/E/F/G, AV-8B, being flight tested on the T-45, and E-2D fixed-wing aircraft, and ready for deployment on the MH-60R/S rotary-wing aircraft. GPWS/TAWS is a proven survivability safety-backup system that warns the aircrew of an impending Controlled Flight Into Terrain (CFIT) condition. The fixed-wing system has demonstrated its value with four documented aircraft saves over the past 10 years. There is a demand for an equivalent protection system among the rotary wing community. The following details unique aspects of a TAWS design that has been developed and implemented for use on rotary-wing aircraft to fulfill this need.
