Default Backup for Electrical System Failure

I just bought an RV-12 with the SkyView 10" display. Does anyone have any comments about what equipment one should have for a backup if the SkyView is inoperable and you find yourself in marginal weather over unfamiliar terrain? I suppose that a hand-held radio, manual compass and a portable GPS would be sufficient to get out of trouble. Any other thoughts?

I'd go with an iPad Mini (with ATT or Verizon option so that you get the built-in GPS) with Foreflight--self-powered, gives you moving map--just missing the attitude info. Our Skyview once showed us flying 7000 ft BGL (below ground level) for about ten minutes, but the Ipad told us otherwise, until the Skyview slowly got its bearings.

Default Add some 2 1/4" backup instruments

Jim,

You could consider adding some 2 1/4" backup instruments as I have done. I used instruments from UMA. UMA was also willing to silk screen the white and green arcs, ect. on the airspeed indicator.

I installed a vertical card compass as well, but not sure how well that will work out as I have yet to try to swing the compass. First impressions are it will be OK ... but will not know for sure until later in the week (weather permitting).

Plan to also have a notepad as a backup on cross country trips ... plus have Garmin Pilot on my smart phone as a backup for the notepad.

Return from the future: Was not able to swing the PAI 700 vertical card compass to my satisfaction even with compensating balls and Mu-metal. However, an Airpath C2300 compass was able to be successfully swung ... see post 18 in this thread for more info.

Below is a photo of my panel.


Happy flying,

For the given situation, an Iphone with Foreflight or equivalent would be all that you would need if you are VFR. You could even call ATC on the phone without a backup radio. Might want a headset adapter for the phone.

I find it curious that no one has said, "Carry a map".

The GPS part of the phone works fine at any altitude.

John and all,

Any luck with the standby compass? Anyone install a liquid filled/whisky compass? What is the logic, all be it legit, to not have to have a stand alone none-electric compass?

Thanks for any ideas.

Doug in IL

Add a Dynon D2 Pocket Panel and a Garmin 660 Aera.

You can wire the D2 and 660 into your electrical system so they are always charged. These two units are simple to install and light.

If you are really worried, toss a handheld radio and extra batteries in your flight bag.
