The Colombian Army (COLAR) has taken delivery of the first two helicopter terrain awareness and warning system (HTAWS)-equipped S-70i Black Hawk helicopters from Sikorsky, at the company's assembly and flight operations facility in West Palm Beach, Florida, US.
The aircraft are scheduled to join five other S-70i multi-mission helicopters purchased by the COLAR to enhance combat capabilities in January 2013.
Sikorsky army and air force programmes vice-president, Jennifer Caruso, said the HTAWS is designed to provide military operators 360° situational awareness in low visibility, day or night, and at altitudes as low as 75ft.
"As a new baseline capability for all S-70i Black Hawk aircraft, this high-resolution system will enable aircrews to perform their demanding missions with greater safety and effectiveness," Caruso said.
Equipped with S-70i's night vision goggles compatible sunlight-readable display, dual GPS/INS system and digital map, radar altimetre, heading system and air data computer, the HTAWS is customised for combat assault and utility missions needs, and displays the GPS location, along with terrain, roads, obstacles and transmission lines.
Manufactured jointly with Sandel Avionics, the system can be adjusted to one of four sensitivity modes, including normal, low, tactical, and obstacles only to help reduce false alerts during low level flights, and also provide audible warnings through the aircraft's internal communications system to alert the pilots to obstacles.
Besides HTAWS, the helicopter is also fitted with a rescue hoist, an integrated vehicle health management system capable of monitoring the engines, transmission and rotors, as well as additional radios and unique mission equipment.
