True Airspeeds

Keven,

I'll scan a couple of the performance pages out of my 1977 POH for the P-model and post them. However, generally speaking, 2400/31 at 16,000 will net 67% power and about 192 KTAS, give or take on a stock airplane. You really need to be up in the higher rarified air to get the max cruise speeds, which would be FL200, and the numbers appear to be 2500/33" for 75% and 205 KTAS with 159# on fuel flow. Unless you're really going far, it doesn't pay to go that high. We find most of the flying in the 10K to 15K range to suffice, and running conservatively, 180 to 190 KTAS.
