Performance Processor

 (a)  The performance processor performs most of the functions associated with performance computations. These functions are vertical steering guidance (relating to target speeds) and flight envelope protection. It also has a Central Processing Unit (CPU), which is physically identical to the CPU in the navigation processor.
