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????

Man who teach me to fly he say, "Never ever blow in pitot, altimeters are
not designed to deal with being blown"
If you must test it seal the tube with your finger and rub the tube. The
heat produced will warm the air enough to increase the pressure and cause
a small indication or better yet put a manometer on it, that will tell you
that the instrument is work AND if you have a leak. Of course if you have a
pot pitot gnore what I have written.
