Jeff, what you have to lose is time if your inspector won't approve it.  The inspector or DAR might pan such a cheapie as regulations require a compass.  Would they allow it if you have an EFIS with compass?  Better ask.

Correct but there is no TSO requirement for the type of compass in a EXP-HB. As far as an EFIS as a compass  they should.

The actual wording is "magnetic indicating device" I believe. I have seen a

number of (approved and flying) panels with nothing but an EFIS.

The DAR that tells you what to put in your airplane is not doing his  job.... His job is to inspect your aircraft and make sure it is in a "Condition  for safe operation" and if he wouldn't give you an airworthiness certificate  because you had a cheap compass than you my friend have pissed off your  DAR. If you were correct in your assumption then he could also say you  can't fly with that Stewart Warner Tack or that car motor. The Dynon is not  TSO'd either. Just because something costs more doesn't mean it's better or not  worthy of flight.

CFRs state that your aircraft must have a "magnetic direction  device".   Doesnt say make or ect....

Exactly, if your DAR refuses to  give you an airworthiness certificate because of your compass, fire the son of a bitch and find someone else. He obviously doesn't know his job. There's no requirement for an aircraft approved compass in a home built.

I find a compass a useless piece of avionics in today cockpits. With my Dynon/Sensornetics and GPS why the heckdo I still need a compass. Oh right the Canadian Government will not give me a flight authority without a “Whiskey Compass” Not a remote compass like my Dynon, not a card compass or a directional gyro but  a Whiskey Compass.   

   

I think I have finally figured out why!! If I go down in the frozen north wilderness of Canada I can crack open my whiskey compass and drink the contents, blindness would follow shortly. The fine gov officials know that I would not want to see just how screwed I am after they cut spending on our search and rescue resources again.

I actually use my compass all the time in my boat. I've actually had times where either the LORAN wasn't picking up this last go round, it actually stopped working, while I was in the geographic center of the Delaware Bay, that's 12 miles from anything. 12 miles from anything on a hazy windless flat day at slack tide at 12 noon and you can't see any land, you have no idea which direction is what. Couple that with concentrating on fishing for 2 hours and you definitely don't kow which way you're looking. It's like being in IMC. I've been flying on borderline VFR days and at 1,800 feet, it's like looking down into a fishbowl with a small circular window surrounded by hazy, and that's actually legal VFR. 3 miles of visibility at 1,800 will give you a cone about 135 degrees to see down, and you can't see the horizon. If you're electronics give up even in that kind of legal VFR it's probably good to have a compass onboard. Maybe you don't get that kind of hazy weather up in Canada, but in Jersey it's the norm.

 His job also is to see that the airplane meets FAA regulations.    If regulations require a magnetic compas, some units MAY not meet this  reqirement if it exist.  Bob U.

My DAR looked at my vertical card compass and must have thought it was lovely.  At that time, that was the only type of direction indicator I had.  This is a non-issue.
