I am by no means an aerodynamicist myself either, but I'll give my 2 cents. Like you said, as smooth surfaces as possible reduce drag and therefore improve their flight dynamics. For example on gliders, it is normal to wash the entire plane after a days worth of flying because of the squashed bugs

All the Cessna 172's I've seen have had protruding rivets, but the heads don't stick out much, and the paint smooths out the edges to the point that they're just gentle bumps -- a 172's wing doesn't look like a steam boiler. IIRC, the Mooney has countersunk rivets, which is why it can go so fast.

Here's a bunch of random photos from a 172S: http://hellosimon.org/35117/ There's some close ups of some rivets in some of them. Hope that helps, Simon On Tue, Apr 13, 2010 at 4:48 PM, Stuart Buchanan wrote: > Bertrand wrote: >> This is some nice artistic/graphical work indeed, however, I am a
