ALENIA - Aeronautica has been involved in Digital Autopilot design for the AMX and EF 2000 programs. The AMX is a subsonic attack aircraft whose Flight Control System is based on Fly-by-wire technology, incorporating an Hybrid Analog and Digital Flight Control Computer for Control and Stability augmentation in pitch, roll and yaw axes, which guarantees the aircraft capability of full performance; in addition the Flight Control System has also a conventional mechanical back-up in the pitch and roll axes, which guarantees aircraft safe re-entry after failure of both hydraulic and both electrical circuits. The paper deals with the development history of the AMX autopilot through design to flight test. In particular the paper addresses the design to specification relationship, the system development and clearance process and the flight test results. The EF 2000 programme is an international development for an agile, highly unstable Fly-by-Wire Air Superiority fighter. Within the EF 2000 consortium ALENIA has the responsibility for Basic Autopilot design. This design, currently in the early stages of development, poses peculiar problems due to the interaction of Autopilot (external) feedback loops and the basic stabilization (inner) loops. The paper address these peculiar aspects in conjunction with the specific design methodologies applied.
