Well spotted Stuart. They look very much like protruding rivets. May be what I reported above is limited to some specific class of aircrafts ? A Cessna C172 is a relatively cheap aircraft flying at low speeds, may be this is why Cessna are using protruding rivets (which are cheaper than countersunk rivets). May be it only makes a difference at higher speeds ? It seems I have extrapolated my experience to an area where it does not apply ^_^ As you may have guessed I am not an aerodynamicist myself, moreover my own experience is limited to airliners where, I think, the criteria are more stringent than for small aircrafts... Or may be in Cessna the design office have won the battle against aerodynamics ? ^_^ Anyway my contribution was not much worth it... Next time I will check closer ^_^ Cheers, Bertrand. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
