it's not just a simple pressure if it's in the tail and there's a fan
blowing on it, you don't find aircraft with the Pitot mounted behind an
engine either.there is a reason they put alternative Pitot and statics on
motor gliders today...most newer gliders do have the multi probes
(pitot-static-TE) in the fin.they all work typically "best" there but they
intend these to be switched to alternative sources when the motor is being
used.....
next time you ask someone to test your pitot are you going to ask them to
blow really hard ?? or just lightly?.and the reason for this would be????

Which manufacturer intends the ships's ASI to ever be connected to (or
switchable) to a tail mounted pitot and/or static? The ASI should only
be connected to the nose pitot and fuselage main static. A vario/
flight computer (like my C302) might be switchable between both (as it
is in my motorglider).

Even if it was connected that way, which still seems awfully wrong for
an ASI, I do not expect the "fan" wind speed plus actual airspeed
induced pressures to damage an ASI.
