REFLECTOR: STICK & RUDDER

In case you are interested, here is the difference:

 
These are from:

You should not use "full deflection of control surfaces @ VNO. VNO is
Faster than VA

Thanks for the definition.  I looked in my handbook and did not find a
Va but there is a Vno (maximum design structural cruising speed) which
is the top of the green arc.  I don't know just what the difference is
but my manual puts it at 170 Knts.
 
Tom,
 
Here's what I think is happening from your description.  First I think
that your left winglet has more tow in than the right one and this is
why you had to shim the right rudder.  Second I believe that full right
rudder at high speed is twisting the top of the winglet to the point of
a negative angle of attack in the relative wind causing the winglet to
flutter, not the rudder. I am concerned that you are exceeding the
design limits of your aircraft and are on the brink of causing a
catastrophic structural failure.
