I Needed to think about Instruments in my panel but as the only increment I have at the moment was the compass I decided that I would fit it for something to do on this very wet day. I first made a flat just in front of the front window. This is exactly the same level as the door sill. And is at exactly 90 degrees to the aircraft. The compass bracket is fitted the same angels and drilled and bolted to the flat area. Cool I now will always know which way my Europa Is Pointing.
