My DAR wouldn't hear of not having a wet compass...even with two separate panel mounted efis systems with backup batteries for each. If it's driven by electricity it can fail...in his words. Have never even glanced at it...waste of my panel space.
In the real world who cares about magnetic heading? Track is the important thing. Donning the flameproof suit now......
ATC still cares quite a bit.
Actually I've found that not to be true. When you get a heading (except for a charted departure or arrival) they are guessing at what heading they really want you to fly. They will then make corrections as needed for you to fly the ground track they want.
CAR 605.14:Yes, it is a requirement in Canada...
Note that by the wording of the regulations, a Dynon D10A would meet this requirement, as it has an internal backup battery and does operate independent of the electrical generating system.(d) a magnetic compass or a magnetic direction indicator that operates independently of the aircraft electrical generating system;
That DAR mentioned earlier is basically demanding a higher level of reliability for heading information (2 efis and a whisky compass) than he is for the engine...
I believe a WHISKEY compass is still required equipment for a VFR airplane. A direction finder NOT reliant upon power.......
Someone insert the FAR's here..........
I would not fly without one. I cross check it all the time against the GPS for reference. I work around electronics all day long in my Paper Mill. I am amazed at the issues that pop up from electrons not flowing in the right direction.
No, it is NOT. I quoted the FAR for you above. It says "magnetic direction indicator". That's all. It doesn't say anything about power, or no power, or anything else.
That would be a choice you can make. But it doesn't mean they're required.
This is correct in the USA.
Mel, do the latest EAB Op Lims still specify that flight instruments are not required per 91.205 for day VFR? I poked around on the FAA's site and kept running into outdated links.
He's actually demanding compliance to a requirement which doesn't exist...he's making up his own.
For the life of me I do not understand the seemingly arbitrary "rules" people keep running into during inspections. The FAR is quite clearly stated...91.205 says "magnetic direction indicator". Let's see...a magnetometer senses the direction, and it's indicated on the screen. It's magnetic, and it indicates direction.
Requiring an additional "wet compass" is going beyond the FARs.
SBLACK is from Canada where different regs apply.

Part 91.205 only applies to EAB for night and/or IFR operations by Operating Limitations.
