Topic: A Pitot-tube windspeed...maybe?

Anybody seen this before?

[CW2274]

Measures airspeed from  9 MPH to 350 MPH (15KPH to 563KPH)
If you need this where you live, I don't want to be there.....Oh wait, I do....

Guilty...by proximity!

This picture was the first thing that came to mind:



If pilots are covering pitot tubes between flights to keep dirt/bugs out, how suitable are they for use in a 24/7 weather station which we all know are magnets for both...and also birds?

Probably passable in a handheld portable wind meter, though.....

I was thinking more about a "combined" wind VANE (direction) and ANEMOMETER (velocity)...basically an 'aircraft pitot tube wind vane'.

And, the reason pilots always cover/protect the pitot tube is because their LIFE depends upon it working 100% all the time, so it's protected until in actual use, ie: flight time.

I was flying with my dad when I was 10ish and the pitot wasn't working upon landing. I didn't get it then, but the trouble in my dad's face was not good, landing was over power lines on a short grass runway...all I remember is the stall warning horn constantly blasting, til he put it down. That was fun...

There was a fatal crash on takeoff from our local small airport several years ago.  Accident investigators found the "remove before flight" ribbon and pitot tube cover still in place. 

Just speculating that the reason why pitot tubes are not commonly used in fixed-location weather stations is because they are vulnerable to being obstructed by environmental elements like bugs, dirt, water/ice, etc.....

Pitot "icing" was the cause of the B2 bomber crash at Anderson AFB on Guam.

Just received this info from Dwyer Instruments in response to my question about using a pitot-tube for "home" weather measurement:

Wow, does this remind me of being a kid again! I wanted one of these bad in the early 70's. Shocked they're still making this.
Thanks for the flashback!
