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.

"The LCR-100 helps to make automated, precision approach to offshore oil
platforms a reality, while improving safety margins and increasing navigation
accuracy in low visibility conditions," said Eckehardt Keip, managing director
for Northrop Grumman LITEF, the company's German navigation systems
subsidiary.

Northrop Grumman LITEF attitude and heading reference systems, which feature a
high-performance, fiber-optic gyro-based inertial measurement unit, have been
standard products on the S-92A since the aircraft's production began. This
latest LCR-100 offering expands the product's capabilities that are
particularly suited to the demanding rotorcraft environment, including search
and rescue operations and offshore service.

Northrop Grumman is a leading global security company providing innovative
