Bill,
 
Is that with the prop pulled back to high pitch (low rpm)?

Subject: [LML] Glide Ratio for the Lancair IVP

With non-feathering prop (and an actual engine failure) I got 1000 fpm at 120KIAS. So I use 2 nm/1000ft for planning. I notice the TAS at high density altitudes seemed to increased the range greatly, but the VSI is also indicated, rather than true VSI, so the ratio remains the same. Initially, I wishfully thought I could get a greater range like 3nm/kft if starting from say FL 250, but this neglects the correction to the indicated VSI.
 Once again L/D max is the same AOA under varying weight, G (turning load factor), and density(?) I think.
Thanks
Bill Miller
