Cessna choosing Northrop Grumman navigation avionics for Citation Longitude business jet
FREIBURG, Germany, 14 Dec. 2015. Avionics experts at Cessna Aircraft Co. in Wichita, Kan., needed an attitude and heading reference system (AHRS) for the new Cessna Citation Longitude super-midsize jet. They found their avionics solution from Northrop Grumman Corp. in Freiburg, Germany.
Cessna officials chose the LCR-100 AHRS, as well as the LCR-100N hybrid navigation unit from Northrop Grumman's Germany-based navigation systems subsidiary, Northrop Grumman LITEF GmbH, as the standard option inertial products for the Cessna Citation Longitude 12-passenger business jet.
This equipment provides critical navigation data to the autopilot and other key systems which help achieve required availability, precision and integrity, Northrop Grumman officials say.
The LCR-100 and LCR-100N consist of fiber-optic gyroscope based inertial measurement units and micro-electro-mechanical system (MEMS) triad accelerometers. The units feature gyro-compassing and hybrid navigation with coasting capability, including ARINC outputs, for precise Required Navigation Performance (RNP) and RNP with approach authorization-required flight operations.
The twin-engine Citation Longitude can fly as fast as 476 knots at altitudes as high as 45,000 feet, and with four passengers can fly as far as 3,400 nautical miles between refuelings.
This selection follows the introduction of the LCR-100 and LCR-100N navigation avionics on the Cessna Citation X+, Cessna Citation Sovereign+, and Cessna Citation Latitude general aviation aircraft.
