at least then it would automate the data capture for
the kinds of performance testing Dick Johnson does.

"Eric Greenwell"

I'm sure he does use an automated logger of some kind. I don't think he's
used a "vibrating panel" for quite a while!

I the spring of 2003 Dick Johnson when he tested my glider he still used
the hard ware he has been using for a long time.
A vibrator for the Panel, he calibrates the airspeed indicator and the
altimeter. He uses his own instruments and takes notes of temperature
and as he flies trough 500ft timed intervals. He is able to do 3 to six
speeds
for each flap setting on one flight from 12000ft. In my case he made two
flight. The other aids are a stop watch, a note pad and at least two if
not
three pencils. I would be able to provide you with a copy of the numerical
data sheet.
