The probes are quite short. You only need a long
probe to move the active part of the probe away
from the stagnation point and flow field around the fin or tailplane.
The tailplane tip chord appears to be very small.
Probably no more prone to damage than the rather
long probe forward of the fin. There's an image
on the Facebook page that seems to show that the
connections will be done manually at least at present.
Interesting possibility to screw up the
connections when rigging. I'd want 3 different
size tubes because we all know about Murphy's
Law. I think it is a great idea though, although
I don't think it will help or hinder variometer
performance. I still favour the landing gear door
location for the TE probe but all pressure TE
varios have fundamental problems which probe
location doesn't fix. I tested that about 30
years ago in comparison to the fin location and
forward of the nose. Seemed best but vulnerable to damage. Needs some kind of
spring loaded mounting which I never got around
to doing as I got interested in fixing the
horizontal gust problem which in the end needed
some new technology to get cheap enough. Now
fixed and only pending a couple of test flights
to verify latest software load in the
Dynamis system.
What we have found is that ALL current TE varios
except for Dynamis tell lies much of the time. As
primary varios they are obsolete.
As for Benalla the JS3 appears to have only just
flown and they have only 3 weeks, 4 max to get
it/them to Benalla. Real squeaky for a boat.
Maybe they are planning air freight. Or maybe
there are 3 and they already shipped two? Gold in the speculation olympics :-)
