Hi Jeff, these are the notes I took during phase 1. Looks like about 12/1 glide ratio is a good ballpark figure anywhere between 80 and 95 KIAS. If I'm near gross weight I'll fly closer to 95 KIAS, but no slower than 80 KIAS. Also, I think the glide ratios would be a little lower down in thicker air.
Time/distance/vertical speed to drift from 9,500' to 7,500' (distance is calculated based on TAS). I did the test at fine pitch as well, and at higher airspeeds (90-95 kts) the glide was almost cut in half.
9.5 to 7.5 at 75 KIAS (85 KTAS), coarse pitch = 2:26 = 822 FPM = 3.45 NM = 10.5/1 GR
9.5 to 7.5 at 80 KIAS (91 KTAS), coarse pitch = 2:43 = 736 FPM = 4.12 NM = 12.5/1 GR
9.5 to 7.5 at 85 KIAS (96 KTAS), coarse pitch = 2:29 = 805 FPM = 3.97 NM = 12/1 GR
9.5 to 7.5 at 90 KIAS (101 KTAS), coarse pitch = 2:21 = 851 FPM = 3.95 NM = 12/1 GR
9.5 to 7.5 at 95 KIAS (106 KTAS), coarse pitch = 2:13 = 901 FPM = 3.92 NM = 11.9/1 GR
