Since summer is upon us here in the Southwest, I was wondering if anyone has anything like a density altitude chart for a Housai Nanchang. There are airports around here with 10,000 ft. density altitude during much of the summer.

I am experiencing similar problems. High density altitude at airfields in the French Alps and no take off tables for altitude in my Yak-18T POH. So I'm using a Koch Chart. I think it still applies fairly well to low-pressure supercharged engines such as ours - it's not as though they are turbonormalised or have a wastegate. Better than nothing, attached.
