The Rockwell Collins Pro Line 21 avionics suite, long a staple in fixed-wing aircraft, has made its first rotorcraft appearance, in a Sikorsky S-61 retrofit program.
The installation of the Rockwell Collins’ integrated display system by Toronto-based Vector Aerospace consists of two 10-inch by eight-inch primary flight display units, TWR-850 weather radar with turbulence detection, AHS-3000A attitude heading reference system, TDR-94D mode-S transponder with ADS-B OUT capability and a dual display control panel.
The Pro Line 21 installation in the S-61 weighs less and helps lower maintenance costs, and it is fully upgradeable for future airspace and technology requirements.
A full line of avionics for rotorcraft is on display at the Rockwell Collins booth (No. 4306). Pro Line 21 components being featured include options such as the integrated flight information system with electronic charting, XM satellite weather and enhanced maps.
