The project capitalizes on the inherent growth provision of Smiths Integrated Data Acquisition Recorder (IDAR) on the IAF CH-53 and UH-60s with the addition of GPWS and Voice Messaging within the IDAR. The program is valued at about $4M to Smiths. The upgrade includes adding a single circuit board to the recorder and minor aircraft wiring changes. The ability to add functionality within the IDAR is a significant advantage in terms of weight reduction and cost savings.

The system performed well on all flights and demonstrated the benefits of the audible alerts in providing pilots the reaction time necessary to avoid Controlled Flight Into Terrain (CFIT) accidents. The system was evaluated during UH-60 low-level operational flights and its warning mechanisms were revised to provide CFIT warning for these missions without exhibiting nuisance alarms. Testing included system warnings for CFIT, altitude loss following take off, potential tail strike situations, unsafe gear position, excessive bank angle, descent below the radar altimeter low altitude warning settings, and Voice Messaging Unit (VMU) warnings.
