Core GFC 500 System
In addition to the core autopilot functions, the GFC 500 incorporates an independent
monitor that uses inertial sensors to determine what is happening to the aircraft. By monitoring
aircraft attitude, attitude rate and accelerations using these independent sensors, the monitor
can shut down the autopilot if it determines the aircraft has exceeded predetermined limits.
