IMPULSE ENGINE CONTROL The impulse propulsion system is commanded through operational software routines stored within the spacecraft main computers. As with the warp propulsion system command processors, genetic algorithms learn and adapt to ongoing experiences involving impulse engine usage and make appropriate modifications in handling both voluntary external commands and purely autonomic operations. Voice commands and keyboard inputs are confirmed and reconciled by the current active main computer, and then handed off to the IPS command coordinator for routing to the engines for execution. The IPS command coordinator is cross-linked with its counterpart in the WPS for flight transitions involving warp entry and exit. Specific software routines react to prevent field energy fratricide (unwanted conflicts between warp fields and impulse engine fields). The command coordinator is also crosslinked with the reaction control system (RCS) for attitude and translational control at all speeds. Æ
