Avionics suite -- Pro Line 21 from Rockwell Collins used in S-61 helicopter display upgrade

Posted by John McHaleCEDAR RAPIDS, Iowa, 11 March 2011. A Sikorsky S-61 long-range helicopter is now using a new Pro Line 21 integrated display system (IDS) from Rockwell Collins. Vector Aerospace in Toronto worked with Rockwell Collins on the avionics retrofit, which is the first time Pro Line 21 has been used on a helicopter.The flight display provides pilots with increased situational awareness and a greater sense of security, especially when flying under strict instrument flight rule (IFR) conditions. The Pro Line 21 IDS features an integrated design that reduces unit count and weight, resulting in lower operating costs for helicopter flight departments through reduced aircraft maintenance and greater fuel efficiency. Additionally, the system is designed for easy adaptability to meet future airspace requirements.The Rockwell Collins Pro Line 21 IDS retrofit package on the Sikorsky S-61 includes:- two 10 by8 inch liquid crystal display (LCD) primary flight displays (PFDs);- solid-state TWR-850 weather radar system with turbulence detection- AHS-3000A Attitude Heading Reference System (AHARS);- TDR-94D Mode S Transponder with ADS-B out capability; and- a dual display control panel (DCP).
