Some idiot at TC offered an interpretation that because something is connected to said electrical system, it therefore cannot operate independently from it. Really you have to read the interpretation to believe it, makes NO Sense.

So we in Canada are stuck installing wet compasses, despite the clear intent of the rule otherwise.

This issue drives me so bonkers, I expect I will try to fight it when my time comes!
Keep in mind that not only do you have to fight TC on this, you have to fight MD-RA as well. MD-RA has internal policies that prohibit inspectors from signing off an aircraft that does not have a wet compass. Not only that, they can't sign one off that doesn't have a 406MHZ ELT either, never mind that there are no regulations requiring a 406MHZ ELT in Canada.

When I imported my RV-6 from the US, it had a wet compass, but I removed it when I installed the Dynon D10A, that has it's own internal, battery backed, magnetic compass. You can *remove* the aircraft's electric generating system, and it'll still work. It came with a 121.5MHZ ELT too, but this was (just) before MD-RA changed their policy.

FWIW, I don't have a wet compass in my plane. I do have 5 GPS's (1 IFR, 2 VFR as part of the EFIS, 1 VFR on my tablet, & 1 VFR on my phone).

I'll take flying a partial panel approach with one of the VFR moving maps over a compass any day of the week. YMMV....

Rob - once again, I'm going to sound like a cantankerous old phart here, so I'll ask in advance for your indulgence...

MD-RA does NOT and CANNOT require a 406MHz ELT be installed. They do require an ELT be installed, and it must meet TSO C91a or newer. It cannot be one of the original TSO C91 ELT's - these have been ineligible for new installations for quite a few years now. The principal differentor between the 91 and 91a units is that, with a rare exception, 91a units have cockpit-mounted remote control panels, whereas the 91 units do not have. It is important to understand that some of the original 91 models could be activated remotely by a simple cockpit-mounted switch - this does not constitute the remote control panel functionality that came along in TSO C91a.

Again, MD-RA does not enforce any requirements for 406MHz, or at least they should not. Every MD-RA inspector is an individual, and human, thus capable of incorrectly interpreting their marching orders from head office. If an MD-RA inspector says a 406MHz ELT is required, please ask that inspector to show you the basis of that requirement, in writing. That should stop the argument in its tracks.

As Marc points out, but more generally interpreted, MD-RA has no regulatory powers. They can only apply the rules as they exist. We had this discussion here a year or two ago regarding the requirements around the avionics checks and when/for whom they are required.

If they make you get your avionics "check" before first flight (even when nowhere controlled airspace) and a 406 ELT, they have over stepped their bounds and imposed on you regulations that do not exist.

At the same time, it is true that each inspector is technically an individual delegate ... so maybe one could interpret the compass rule correctly!?

Somehow, flying IFR with a dead glass panel and just a compass would not be very much comfort for me.
