New aviation-safety sensor technology that relies on millimeter-wave radar and infrared imaging is permitting C-130H transport pilots to land their aircraft in zero visibility conditions--including heavy fog, smoke and snow.

A recent test at Edwards Air Force Base, Calif., proved the validity of BAE Systems' autonomous approach and landing capability, which was sponsored by the Air Force Research Laboratory.

Clark Freise, vice president of defense avionics for the company, noted that the "technology essentially lets aircrews maintain their vision through all weather and obscurants." The system and demonstration, which reached fruition under an $11.4 million contract, could be adapted for other military and commercial aircraft, he said.
