Does anybody know if ground effect lowers your stall speed?
+++
I always believed that it did not, so I was surprised to read the
compelling evidence from John M, viz., "Mine actually lifts off at 37
knots in ground effect and will fly a foot or so above the ground
however stall a

Technically speaking, the stall speed decreases asymptotically to zero the
closer you get to the ground but

I think my latches will be OK, but their attachment to the canopy frame is
still suspect. I plan to epoxy an aluminum angle over the edge of the frame
and connect the latch to it, rather tha

Ground effect would be equal to approx 1/2 the wingspan. I doubt
that there is an airplane flying that can land without experiencing
ground effect.

Span on a Wilga is 36'-6", making the half-span (one wing) about 18'. Half
that wingspan is about 9'. Take a look at the chap standing next to the one

Larry I am gonna knock just alittle more dust off.
Ground effect actually begins the height above the ground that equals the width
of the wingspan, and is most pronounced at half the width of the wingspan
(where we feel its effects the most). Ground effect for fixed wing aircraft is
defined as

Not many of you are old enough to remember a gentleman named Max Conrad
who set many long distance records in the 50's and 60's.
He claimed to have achieved these long distance flights by flying only a
few feet above the sea and staying in ground (sea) effect.
Must have worked OK for him.

Does anybody know if ground effect lowers your stall speed? I would think so,
at least some small amount, but I don't know for sure. If so, how much?
