FMS Kalman RNAV

A Kalman system is used on a system where there are multiple inputs - in this case, the FMCFMC —Flight Management Computer which receives navigation information from many different sources. A kalman system uses mathematical algorithms to attempt to filter out "noise" from erroneous sources - so if, for a example, an NDBNDB —Non-Directional Beacon said you were 2 nm away from the position that the GPSGPS —Global Positioning System (USA), VORVOR —VHF Omnidirectional Range and INSINS —Inertial Navigation System said you were, it "smooths out" these data fluctuations and comes to the best solution.
