For example, the left side of the bezel houses three color LEDs located adjacent to the AP (autopilot engage), FD (flight director on/off) and YD (yaw damper on/off) buttons, so there's never any guessing which is engaged.

For example, there's a pitch/rate thumbwheel, rather than a knob or rocker, and there are dedicated keys to engage pitch, rate or airspeed vertical changes, plus dedicated keys for the flight director and--a new feature--a yaw damper. (Considering the SR22's lack of excessive adverse yaw and minimal yaw-roll coupling tendencies at cruise speed, we're not sure how necessary the damper is, but the AP has it and customers of high-end aircraft will probably want it, even if they don't ask for it.
