Abstract

This paper investigates the use of fiber optic comminucation media in a digital flight control system. A number of recommendations are included to allow reliable use of fiber optics in this application. A proposed fiber optic media, AFDX, is studied using dynamic, real time models. The effect of latency introduced by AFDX is studied for an F-16 aircraft model. Finally, the effect of latency and jitter are correlated using a simpler induction heater model and PID controller.
