Dr. Jack,
Did you solve your plugged up *hole*, problem?

Just a bit of information for all the *rule-followers*, out there. Your ships
manufacturer specifies the pitot and static sources that must be used in order
to make the airspeed read the same as it did when the design was certified. The
computer manufacturers tell us to use the same pitot and static that our
airspeed indicator uses. SO, we should use the same one that is specified by
the sailplane manufacturer. This applies to type certificated ships as well as
those licenced in the experimental category. Because, your experimental
airworthiness certificate says something like, This ship will be operated in
accordance with its flight and maintenance manuals, and that specifies the
source of pitot and static.
