Subj= ect: [FlyRotary] Re: VNE / Flutter Testing

I read somewhere (I can't recall, sorry) that basica= lly you speed up a couple of knots, let go of the stick, and then bump it f= orward and see what happens (being ready to grab it in a hurry).  the = the same with elevator, rudder, and aileron.  Speed up a couple of mor= e knots, try it again.

The idea is that you can have a "metastable" = situation where there is no flutter until a gust of wind comes by, at which= point you're 30 knots over where it can happen, so it happens in a hurry.&= nbsp; Creating the disturbance yourself prevents it from being a metastable= condition.

Ernest,
   The procedure is to test with many steps increasing= speed in small increments always ready
to reduce throttle and increase AOA at the = slightest indication of flutter..............
 

Dang!  I was hoping = somebody had come up with something better than that.

Oh, well. = ; At least that gives me a "reason" to take up parachuting 8*)
