Paul:

I got a nice manual pneumatic switch for use in my oxygen system from
Mountain High a few years ago. You might check with them.

Hi,

I received a few very nice e-mails from reputable sources recommending the
use of a pneumatic switch to switch between TE and Static input for a
motorglider. That is good information. This newsgroup is fantastic!

It was suggested that the switch could be made to be automatic. That
sounds
great. It is my understanding that even very small leaks can cause large
inaccuracies in TE functionality - so we must be careful about that of
course. Does anyone have any recommendations for manual or automatic
pneumatic switches? It would be great to get feedback from someone who
has
done this already.

Thank you,

Hi,

I have a question for motorglider owners. I sell variometers and TE
probes
but I'm still learning. A customer is building a Europa motorglider and
he
is wondering if he can mount a TE probe on the fin and connect it to the
variometer, or will the propwash cause problems. Is it necessary to use
some sort of pneumatic switch to switch between TE and static input for
the
variometer?

His pitot and static ports are on a boom that is mounted to the wing.

Thank you,
