Date Posted: Thu, Dec 13 2012, 12:19:05 GMT Hi everyone - me again. I recently did my bi-annual check flight with a different instructor (Chris). This included a Practice Forced Landing from 2500 ft onto a long grass airfield. The throttle setting specified by Chris and resulted in a sink rate of 500 ft/min at 75kts with 0degs flap. I wonder how this sink rate compares with that of a stalled engine. My prop is a Warp Comp which should (I guess) have low drag when stalled because of its narrow profile. Does anyone have any figures for best (dead engine) glide speed and typical sink rates under this condition? Also during the check flight I was asked to do some “wings level gentle stalls”. Firstly at slow idle (all gentle and benign) and then with a bit of power applied. With power applied after the usual pre stall warnings the high nose up suddenly flipped to (guessing) 20% nose down with a 30 degree wing drop. I’m guessing that the prop-wash over the root of the wings caused the outer section of the wing to stall?- rather than the idle power stall when perhaps only the roots stall and the tips keep flying due to the washout? Any thoughts/experience on any of the above appreciated. Cheers Bob [ Next Thread | Previous Thread | Next Message | Previous Message ] |
