Bohli Compass

What is a reasonable value of a Bohli compass? does not appear to have ever been installed
Does it still have value?

r/Jim

No, it's worthless now. Please send it to me and I will dispose of it
properly. :-D

I hate to see Dan have to go to the trouble of opening the package so send it to me, collect!

Maybe I should put it on e-bay and see where it goes. Sounds like it is worth more than I thought.

I truly don't know what it's worth, if anything.

I've read that, properly set up, it can be used to fly in clouds. I've
also read that it was banned in contests in the US for just that
reason. It would be fun to have as a toy, just like that J-8 attitude
indicator that I've had in a box for close to 40 years.

I've flown with Bohli compass and it's main use is same as directional gyro's. When IMC (or VMC, of course) you can straighten your turn to correct heading right away if compass is tilted correctly. With normal Airpath compass procedure inside cloud is to straighten to any direction, wait 15-30 sec to get compass reading, then calculate how many seconds to make 30sec (or 1 min) standard rate turn to correct heading. This takes easily couple of minutes in all. These days any modern GPS gives you track reading at 1 hZ, which makes Bohli compass totally obsolete. You can not fly IMC with only Bohli compass, that has to be some misunderstanding.

Weren't they once banned from use in contests?

In continental Europe. Not sure if that expanded to the UK.

The ban was because a very skilled pilot could cloud fly without gyro
instruments, just using a Bohli compass. Not banned in the UK because we
allow cloud flying.

Last one I saw sell on Ebay in Europe went for 165 Euro.

They are a valuable piece if in working order.
