Findings of studies on input processing of a digital fly-by-wire system of a fighter aircraft are presented. Objectives were to select a suitable software structure complying with reliability and fault tolerance requirements and to assess its computational load. Ramp and constant input signals with noise were studied based on Monte-Carlo methods. Voting strategies studied and compared include lower-median, upper-median, and weighted average. Execution times and memory requirements of each strategy have also been assessed.
