Abstract
A universal vehicle control router for small fly-by-wire aircraft may include multiple vehicle control computers, such as flight control computers. Each flight control computer may be part of an independent channel that provides instructions to multiple actuators to control multiple vehicle components. Each channel is a distinct pathway capable of delivering a system function, such as moving an actuator. Each flight control computer may include a fully analyzable and testable voter (FAT voter). In the event of a failure to one of the flight control computers, the FAT voters may cause the failing flight control computer to be ignored or shut off power. Each flight control computer may comprise a backup battery. In the event of a power disruption from the primary power source, such as a generator and primary battery, the backup battery may power the flight control computer and all actuators.
