Is there any way to get X to notify me with a sound that I need to turn off the yaw damper before landing?I'm serious.

thanks

No, because also like a RL Pilot you work with a checklist. If you flying a plane, where it is inhibit to shut off the YD its in the checklist.

I don't think there is a native way to achieve that but it could likely be done with a simple lua script that either play a sound or pop up a message onscreen.
You would need to define the criteria to determine this, for example when AGL is below a given number, or when you lower the flaps, or when you turn off AP, etc  or a combination of these factors.
