Synchronization cross-feed system

A synchronization cross-feed system for a thrust reverser having at least first and second sides. Each side of the thrust reverser has a thrust reverser actuation system having a plurality of actuators. The actuators in each thrust reverser actuation system are synchronized by a synchronization system. A synchronization cross-feed system couples the synchronization systems of the thrust reverser actuation systems of the first and second sides of the thrust reverser allowing an anti-deployment mechanisms of each thrust reverser actuation system to serve as one or more of the redundant anti-deployment mechanisms for other the thrust reverser actuation system.
