Northrop Grumman provides attitude heading reference system for Sikorsky's newly certified S-76D helicopter

Northrop Grumman Corporation is supplying the LCR-100 attitude and heading reference system (AHRS) for Sikorsky's new S-76D helicopter, which recently received Type Certification from the U.S. Federal Aviation Administration.

The LCR-100 is a standard component of the Thales TopDeck® avionics suite on the new medium-sized, twin-engine helicopter. Northrop Grumman provided both the LCR-92 and LCR-100 fibre-optic AHRS on earlier versions of the S-76 helicopter platform.

Developed by Northrop Grumman's navigation and positioning systems subsidiary in Germany, Northrop Grumman LITEF, the LCR-100 provides critical flight information regarding the aircraft's position, heading and attitude. The LCR-100 offers precise outputs to the flight control system and has demonstrated high reliability and accuracy in the helicopter environment.

"The LCR-100 has proven its dependability and efficiency in serving rugged helicopter platforms, including previous versions of the S-76," said Eckehardt Keip, managing director for Northrop Grumman LITEF. "We continue to offer lighter products with greater accuracy and performance."
