各位，自动驾驶和飞行指引有什么区别？
自动驾驶就是完全交给FMGC来控制，飞行指引是指人工操纵跟随自动目标？

飞行指引：The FD displays the Flight Management and Guidance Computer (FMGC)
guidance commands on both PFDs. In manual flight, the FD displays
guidance orders to help the pilots to apply commands on the controls in
order to follow the optimum flight path, which would be ordered by the

自动驾驶AP：The AP guidance modes are selected from the FCU or the Flight
Management and Guidance Computers (FMGCs). The AP function is a
loop where, after a comparison between real and reference parameters,
the FMGC computes orders, which are sent to the flight controls. The
loop is closed by real values coming from sensors and given by other
systems (e.g. ADIRS) to the FMGCs. When the AP is engaged, the load
thresholds on the rudder pedals and the side sticks are increased. If a
pedal or side stick load threshold is overridden, the AP disengages.
