I saw one once in a C152 I think...

For vfr in experimentals, no compass or magnetic direction system of any sort is needed. If someone gives you a hard time about a card, just remove the compass!

In Canada a compass is required for day and night VFR with it's corresponding correction card. Both in certified and home-built aircraft.
Make that "daytime VFR"! It is required for night time.
I actually filled the card out - about a year later....when I had nothing better to do....

After very exhaustive research, I have not been able to come with a regulation requiring a compass card for experimental aircraft. I therefore retract my previous statement.If you have an adjustable whiskey compass, the correction card is required.
For compass requirement; FAR part 91.205 does not apply to experimental aircraft (i.e. nothing is required for daytime VFR) except as noted in your operating limitations for night and/or IFR. For night and/or IFR in accordance with 91.205, you must have a magnetic direction indicator. The magnetometer in conjunction with an EFIS meet this requirement.Mel,
I'm sure this has been kicked around before (hopefully not to the extent that the horse is dead) but I was wondering how you look at the need for a whiskey compass if a magnetometer is used in conjunction with an EFIS? I am getting differing opinions as I draw near to finishing up my panel.
Thanks,

Craig is correct. We are talking the MINIMUM requirements, not necessarily what is prudent.Just my opinion,
I think if you are day VFR and buzzing around town for 20 minutes at a time do a couple of rolls and go home you don't need a compass. But if if you are leaping continents and oceans in a single bound, you might want to think twice about not having one. I know what the rules say. But what do you say when the alt/battery die and there you are? No fancy gadgets left just the sun or stars looking at you? And on a 50-120,000 dollar aircraft, what is 75 bucks for a little bit if insurance?

Craig,
Good point but that is why many of the EFIS manufactures offer backup batteries. Also, many of us fly with handheld GPS units, which also contain a battery.
In my installation, should the alt/battery die, I still have a few hours of power in both of those units to find my way safely to my destination.
Remember, whiskey compasses can leak, rendering them inop.
Which brings up an interesting point, how many of us could actually find our way home with just a compass as a nav tool? I suspect not very many.
