Mooney F20 Mystery part

Anybody know what this is?  It appears to be plumbed into the airspeed indicator.

If it's hooked up to the ASI, there must be a [likely hidden] switch on the panel to use it instead of the pitot and impress friends and passengers with high airspeed! Getting prop blast in addition to ram effect from speed should wind that puppy a little higher!

Looks like the mounting bracket for an ADF sense antenna with the wire removed (and mounted backwards)? Normally found on the top of the fuselage with the wire going to the top of the vertical stabilizer.

Maybe it’s being used as a cooling duct for the emergency gear extension crank.

Welcome aboard New Garry!

I don’t think I have seen one of those before...

There are a few versions of airspeed switches used on Mooneys...

Does your plane have electric landing gear?

 

If yes, what does it use for an AS switch..?

Or does it have a squat switch?

Best regards,

Or perhaps Ram air for Piloto's pee tube

I waited to see what the real answer was...but it looks like that's going to take a while!  My thought was a deer whistle...

Yeah, I was so ready to go there...

I couldn't find a WD-40 reference to throw in with it tho...

This is the outside pickup for the Brittain (yes same Brittain as autopilot) true airspeed indicator. You notice it has no knob to adjust the outside temp etc.  They work great and always read out true airspeed. Been a lot of years since I had one of these. Last one was on N2980T which I delivered to a buyer in England.  Was a Meyers 200D

Haha I was just thinking the same - maybe an early relief tube prototype.

As a relief tube there, one must stand up facing the window

Mooneys interiors are capable of many different activities!!
