Your Compass mounting experiences

NYTOM · #1 04-23-2016, 09:54 AM

Looking for input on mounting a whiskey compass on a slider. Has anyone found it impossible with the steel rollbar and center brace causing interference?

I'm getting directional info from two other electronic sources but just like the idea of having a old school compass available.

Anyone? Bueller? Bueller?

I bought the SIRS compass and roll bar brace mount from Vans. I've grown to like it even though I initially preferred the look of Airpath. Was unable to find or make a good mount for the Airpath.

Not flying yet so this doesn't help you much. But my roll bar brace from Vans is non-magnetic stainless steel.

Are you talking about interferance from the roll bar? Im not at that point in the build yet, but I'm pretty sure you have to degauss the roll bar.

I tried to degausse the roll bar but was unsuccessful. I eventually found an acceptable location in the lower middle panel as I had to avoid the welds at the sides and the center top where the brace attaches. I rarely use the compass and rely on the EFIS's digital magnetometer located out in the wing tip.

I didn't bother with a compass on my plane because one is included in the EFIS.

I've the SIRS compass mounted on the roll bar brace. Heads up - if you use a tablet app for nav, the tablet's battery will cause the compass to swing a few degrees, unless the tablet is located to the far sides of the cabin or on your thigh, kneeboard style.

Thanks for all the help. I was afraid that was going to be the case. Probably never use it anyway. Guess I'll save the weight.

I moved a vertical card compass to several different locations in the panel without finding a spot where it worked to my satisfaction. SIRS on the roll bar brace works great.

I'm with Bill, two effis screens, 1 or 2 cell phones, and a handheld compass in the side pocket for emergency that I have not used yet is enough for me!

I had the local FAA FSDO office sign off my RV-10 four years ago. The inspector required a TSO compass in the plane - even though I had two independent EFIS ADHARS units.

No - this is not a requirement that I could find, but such was the cost of getting the plane signed off. Perhaps old thought such as this is working its way out of the FAA.
