Airspeed Indication

[Dusty]

Try a very small restricter under the dash.
I had the same problem.
Rock solid now,possibly reading slightly low at speed and slightly high on approach.
Only a few kts out but ok

Thanks a lot for the information. That sounds like a good fix. I wonder how critical and how small the hole size should be.

BTW, your plane looks a lot like mine. Have you got a larger picture?

I plumbed in a static port and my indicator is rock solid. On the model 7 the factory has a recommended static port location that is low on the left side and just ahead of the lift/push handle.

Hi chuck
The hole can be very small,about the size of a pin.
It is effectively only a breather
Re photo,I recently posted some images on where I fly

Thanks for the neat photos, our planes are somewhat similar.

Thanks for the info. If simply restricting the pitot side doesn't tame oscillations, I'll install a static source. Isn't it amazing the things we do to make a simple airplane complicated.

When it built my series 6 , I placed my static port in the same location! My indicator is calm also.
