All Goose, brick and bowling balls aside.When I had my engine out I was at 2000 Ft AGL.I landed easily on a field 2000 ft away while making a 180 in to the wind.If no turns where made and wind was 0, I would expect a distance of 4000ft.Not knowing the optimal glide speed, I kept 50 MPH.My guess would be a engine out glide ratio of around 1: 2 or 1:3.More importantly the Piet is slow, even with the nose pointed down it willtake some time to get there.With the throttle at Idle the glide ratio depends on what idle RPM yourrunning and the pitch of your prop.A low pitch Prop and a engine at low idle (600) creates more drag than withthe Prop at standstill.Hans "Phillips, Jack" To Sent by: owner-pietenpol-l cc ist-server@matron ics.com Subject RE: Pietenpol-List: Re: Corvair Flyers 05/08/2006 07:55 AM Please respond to pietenpol-list@ma tronics.com I once heard a Grumman Goose pilot describe its glide characteristics as:If you lose both engines in the Goose, throw a brick out of the cockpitwindow to see where you will land. After landing, run quickly from theairplane to avoid being hit by the brick.You and Galileo are right, if there is no air. In the presence ofaerodynamic drag, a tumbling brick will fall considerably slower than abowling ball. Now if you can manage to stabilize the brick to fall narrowend first, it might actually go faster than the bowling ball. Neither willfall as fast as a Pietenpol seems to with power off.Jack-----Original Message-----

The Pietenpol glides like a parachute...A very small, round, non-steerable parachute, with a big weight on it.Mike ----- Original Message -----
