I have only been able to find examples of auto-land systems for tricycle gear. Is there an equivalent for taildraggers?
I realize taildraggers are more commonly used in VFR conditions, so there may not be a sufficient market draw solely based on the weather argument (as would be the case for e.g. commercial air transport). I also realize that taildragger aircraft tend to cost less, thus making it harder to justify investment in an avionics capability that would likely be expensive. But are there any other reasons why they are so much less common (if they exist at all)? The physics would be different, but modern control systems are capable of handling those...
Follow-Up Feb 23: Since there seem to be no obvious examples - and in light of the constraints identified above and in John K's answer - what would be the simplest (read: cheapest) taildragger auto-land system that would provide meaningful benefit (e.g. prevent ground loops)? For example, would a simple "Heading Hold Mode" augmentation system be helpful? If not, why not?
Fun Fact: The closest to a "landing system" that I could find is Brodie Landing System for the L-4, discussed here.
