In the AC103 appendices, there are graphs to work out acceptable designs without having to do bothersome and accurate testing of stall and top speeds.
Skip to airfoil lift coefficients, namely Cl=1.6; Camber over 7%, that's easy enough to determine, but relatively flat bottomed? I'm looking at a flatish bottomed airfoil: the F5FRAS13 looks about right for my tandem; Page Title
Does anyone know how 'relatively flat-bottomed' is defined by the FAA?
