Default Prandtl multi probe receptacle used for TE only?

Hi Matt!

I have a Prandtl type receptacle in the fin of my ASW27.
The previous owner converted to to TE probe only, by tying off the static
and pitot lines behind the panel. Anything wrong with this set-up?
I get my static from the ports on the boom about 2/3 back.


You mean a 3-way probe, right?
The probe pitot and static are better than fuselage ports (though pitot
is easily wiped out by a bug). If your instrumentation is working OK with
fuselage ports, why mess with it?

I guess there would be more potential for leaks, at a minimum.


Nope.

will the extra volume of air connected in the unused tubes create
any adverse effects on the TE line?


No, they are not connected in any way.


See ya, Dave
