Northrop Grumman Corp announced that it is supplying a modified LCR-100 Attitude and Heading Reference System (AHRS) for the newly certified offshore rig approach feature on Sikorsky's S-92A helicopter. The automated rig approach capability assists offshore oil operators with approaching and landing on oil rigs and platforms by guiding the aircraft to location coordinates entered by the pilot. The system is expected to reduce cockpit workload and enable safer landings, especially in challenging weather and operating conditions. The LCR-100 AHRS provides critical navigation data to the helicopter's flight control computer to help achieve the required integrity, availability and higher levels of precision needed for the rig approach capability. The unit was modified for rig approach to provide horizontal and vertical figure of merit data, which are essential to precise flight operations.
