Abstract
In an aircraft using fly-by-wire technology, the flight control functions have been integrated into the integrated modular avionics (“IMA”). The new flight control module (“FCM”) resides on the same data bus as the other modules in the IMA and receives power from the same power supply. In addition, the FCM is also connected to a separate power supply to add redundancy to the system. Several benefits arise from this configuration of an FCM. There is no longer a separate chassis needed for the flight control functions, thus resulting in a reduction in weight. In addition, the FCM now has access to all of the data on the IMA bus, instead of a limited amount of data over an ARINC 629 bus. The FCM provides augmentation signals to the actuator control electronics (“ACE”) to aid in the flying of the aircraft. In the event of a failure of the FCM, the ACE still provides enough control to fly the airplane.
