Abstract
A system includes a first solution engine, second solution engine, output voter engine, and output modification engine. The first solution engine receives first sensor data associated with a first error rate, and determines at least one first flight parameter based on the first sensor data. The second solution engine receives the first sensor data and second sensor data associated with a second error rate, and determines at least one second flight parameter based on the first and second sensor data. The output voter engine determines a difference between the flight parameters, compares the difference to a first threshold, and generates an output including the at least one first flight parameter or the at least one second flight parameter. The output modification engine receives the output from the output voter engine, modifies a rate of change of the output to be less than a second threshold, and transmits the modified output.
