A320 Systems
How the A320 family systems work, for type rating and ATPL candidates — hydraulics, flight controls, autoflight and more, reviewed by the ProPilotLicence captain panel.
Three independent 3,000 PSI circuits. No single failure removes all hydraulic power — but each failure cascades through flight controls, braking, landing gear, flaps and slats. Exactly what is lost and what remains, system by system.
The A320 autoflight system does not merely fly the aircraft — it communicates its intentions through the FMA on every mode change. Pilots who understand that conversation rarely get surprised.
The A320 does not have a direct mechanical connection between the sidestick and the control surfaces except in Direct Law. The pilot inputs a demand; computers decide how to meet it. What changes between Normal, Alternate and Direct law is the envelope protections the computers provide.
