What type of approach system does the Airbus A320 typically use?

The Airbus A320 typically utilizes a fly-by-wire system for its approach and overall flight control. This system replaces traditional manual flight controls with electronic signals. In a fly-by-wire system, pilot inputs are processed by onboard computers, which then send commands to the flight control surfaces. This technology enhances the aircraft's stability and maneuverability, allowing for smoother operation during complex flight maneuvers, including approaches to landing.

The fly-by-wire system also allows for various safety features, such as envelope protection, which helps prevent the aircraft from exceeding its performance limits. The system's reliance on computer processing enables significant advancements in aircraft automation and precision, making it a hallmark feature of modern commercial airplane design, particularly in the A320 series.

While other options reference control systems, they do not accurately describe the technology implemented in the A320. Conventional yoke systems and mechanical control systems involve direct, manual operation, which does not provide the efficiency or safety enhancements offered by fly-by-wire technology. A hybrid control system, which might imply a combination of manual and electronic controls, does not specifically characterize the A320's approach control methodology.
