Default Final Approach Speed

What kind of final approach speeds are you Hatz-folks typically running, while coming down final and over the fence?

DISCLAIMER: I do know that there are variances due to differences in pitot-static system installations

Coming over trees into a short strip down around 50 (mph) at the trees, usually with a little slip to see where the tree tops are. Once clear of the trees, I slip harder and let it bleed off. Final speed at a "normal" runway, 60 or 65.
I did get into a 600 ft, one way in/one way out strip once. Drug it in really slow with a little power. Did it perfect that time so I won't try it again

I've never flown a Hatz but I suspect it is like other Biplanes, they do NOT like it when you get too slow. At a certain speed drag gets the best of lift and decent rates can get interesting and flair becomes problematic. There are many broken/bent airplanes to prove it.

I had the urge to visit a short local strip with trees at both ends in my EAA biplane so I practiced slower/steeper approaches and experienced one of those "Awe S..." moments when the stick came back w/o any change in pitch. Hard was not a sufficient term to explain the landing! I won't do that again either....I hope.

Be careful out there.

In general for biplanes and other high drag aircraft I use at least 1.5 X stall speed for initial approach speed. If that proves too fast/to much float you can make an adjustment .
