we tried it today and saw about 550 ft/min at +/- 63 kts
... But My RV12 POH gives two different things on page 6-10, Complete power failure forced landing:
>Maximum gliding distance airspeed 85 kts
>Minimum rate of descent airspeed 60 kts
Both are noted as flaps up. ...
Best glide speed (Vg) is the speed that will give the best power off L/d, and get you the most dist vs altitude available, so that is the speed you would want to use for the glide ring data.
Any idea why Bill's POH says that speed is 85 kts and mine says 63?
Scott --
Did Van's come up with any "average sink rate" data during flight testing that we could input into our SVs? I realize that there are many variables involved (e.g., flaps, wheel fairings, prop windmilling, operating weight, air density, etc.). I guess I will use 600 fpm for now and will do some testing of my own to establish a useful value that reflects an "average" situation for my use.
