Outerlink, a Metro Aviation company, has completed 30 percent of initial flight tests for IRIS, its ViaSat-enabled satellite communication system, the company told R&WI Aug. 11. Each component is being tested according to RTCA’s DO-160 standards, which specify environmental conditions and procedures for testing airborne equipment. Flight tests are conducted in Outerlink’s aircraft according to their availability, resulting in data for a variety of helicopters. Most of the initial tests have been done on an Airbus Helicopters H135, and two more rounds on an aircraft to be determined are expected within the next 30 days. The first FAA-witnessed demonstration flight is scheduled for October and will be conducted in a Sikorsky S-92. Outerlink says its STC application process is on schedule and advancing in parallel to the flight tests.
