What is the thing you often see hanging off the top of the fin on test flights ?

Looks like a wire with a weight on the end ?

Is it a VHF/UHF antenna ?

I gotta know it's doing my head in.

It's called a trailing cone pressure transducer. Trailing cones give an easy way of calibrating the static pressure error of a pitot-static system.

Here are a couple of info sites.

It's a wire with a weight on the end of it.

I thought it was the cockpit voice recorder as it's unlikely that it would back into a mountain.

IT'S MY HAIR NET!!!!!!!!!!!!!

Thanks Roy, mystery solved !

It's a flumix, carpitchulater. It measures the flumix overload caused by excessive carpitchulation, but only in the southern hemisphere.

But but but...what if you are an A/C...which makes you a closet Canadian...which makes you French?
