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.

I was sure I'd read/heard he was using an electronic logger, at least at
one time. Did he mention if he'd tried one, or if some of the pilots
assisting him used one?
