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????

If it is and the motor was run with the Tail Pitot in use rather than the
alternate Pitot (some gliders will have front and rear Pitot and static
inputs if they come with motors today) you may have damaged the ASI from
the
high pressure .......just a thought

I don't see how the pressure at a tail mounted pitot in a motorglider
will ever be enough to damage an ASI. Not compared the pressure from
airspeed they'll experience from normal flight at different speeds.
And the main ASI would normally be permanently plumbed to the nose
pitot and the ships main static (not a TE or triple probe).
