to support this cycle. The other way you can stem it is to make the stab
fin or wing very rigid and this is why biplanes can have as high a
redline as , say a Mooney might though the bipe might have no balance
area at all and the Mooney would. All the surfaces are too rigid to
allow the cycle to start.
You would think that a greater load on the surface, i.e, "G". would tend
to dampen the action, but the opposite is the case.
Flutter will appear at a lower speed if the surface has an aerodynamic
load on it.


So at a practical level, is it reasonable to say that avoiding a red-
lining of airspeed is sufficient to avoid flutter in small GA
airplanes? Or are there other things to watch out for in normal flight
to avoid flutter? I didn't quite follow the part about flutter at
lower speeds but thanks for the informative post,
