Smile Pitot tube cover

Has anyone come up with a trick way to protect that sharp and pesky little pitot tube? Yesterday I walked past it and put a hole in my arm....that will heal...but I don't wanna damage the little thing by doing that again.

(BTW: local Airport Bums have asked what that is and I them it's my 22 cal. machine gun) :-)!

EBB:-)

Best one I saw was a guy who put a yellow tennis ball over it!

I fabricated a little plastic thread cap over it, made a small hole in the tip, and tied a plastic Do Not Remove to the inlet plugs. Works well?.until it's off and you knock your arm against it!!

We fashioned a pitot blank from a standard aircraft hose blank with a 'remove before flight' key fob (since upgraded to a Red Bull 'Flying Bulls' version!). A small hole prevents pressure change problems.



Prime reason for it is to prevent things climbing in and blocking the pitot tube, secondary reason is to prevent blood loss.

A secondary method is to leave the tow bar attached. Now I am the number one advocate of removing tow bars before you let go of it but on the RV-12, it does help keep peoples skin away from the sharp end of an RV-12....

See the modifications sticky thread at the top of the RV12 forum. A couple of good ideas in there.

Found an assortment of covers from pilotmall.com. Trimmed one down to fit.

I put a 5/16" vinyl screw protector on my pitot tube. Hillman part 881039 from Lowes.
Not only does it protect the pitot tube, it also protects skin. The vinyl cap fits tightly.
I put a very small vent hole in the end of the vinyl cap to prevent stressing the Dynon pressure sensor.
The hole is big enough for light to shine through, but will keep all but the tiniest bugs out.
One time I forgot to remove the cap, but the airspeed indicator and AOA worked as normal.
Those functions depend on pressure, not airflow. If the airspeed works OK with the cap on, then why take it off?
So I have left the cap on for the last several flights with no apparent indication errors.

I used the rubber bulb off a Rogaine eye dropper with a REMOVE BEFORE FLIGHT key chain fob as a flag. I got way more usefulness out of it as a pitot cover than as a hair restorative!😝

Interesting. Wouldn't the smaller hole be more prone to blockages in-flight though?
