Rocketman1988 recently commented “ if you drill down far enough, you will find single point failures”. Yes, carbs have floats and orfices. Mechanical injection has one servo. EFII has one circuit board.
So my question is, under what assumption is a single board EFII system viable for an airplane ? You have 4or6 injectors controlled by a single brain. Not really any worse than a single fluid path to the cylinders ???
OK, then lets use two circuit boards to fire the injector coils. How is that managed if one board goes TU, or they simply disagree ?
Your comments would be appreciated.
