Default Whats your electrical setup?

Not looking to start a war but just curious to what you have on your aircraft and if you fly IFR with it.

"Integrated back-up battery system" - the TCW product.

Thanks.

So, my next question is, if your EFIS has an internal battery backup, you mount a handheld GPS in the panel that has a battery backup to backup the EFIS GPS, and you have a battery powered backup EFIS such as the Dynon Pocket Panel, why would you ever need an IBBS, backup battery, or backup alternator?

I guess I won't need to answer this poll.

Because my LSE ignition doesn't have a backup battery.

Good answer!

However, if you only have one LSE, then there is no requirement to have a battery as a single mag should keep you in the air until you can land and sort things out.

Question None of the above

I didn't vote because my option isn't listed. I have two batteries but both are not full sized. The second one only runs the second Electronic Ignition system. One alternator. VFR only.

I have TWO LSE's, and there is no REQUIREMENT to have an alternate electrical source. But doing so makes a lot of sense.

My plan is to add a standby alternator at next annual.

One battery and one alternator. Backup batteries on both of the Dynon Skyview EFIS. Backup batteries on the Stratus II / iPad. Lightspeed + old fashioned Magneto.

If I lose my alternator, my main battery (PC680) has enough juice to power everything long enough to get safely to the ground.

If I lose my main battery and alternator, I can still fly using my EFIS on battery backup to stay level, my Stratus to provide GPS, and my iPad / Foreflight to provide mapping.

If I lose my IFR GPS (an Avidyne IFD440), I can use my Dynon GPS.

If I lose my Dynon EFIS / Artificial Horizon Display, I can use my Stratus / Foreflight Artificial Horizon Display.

If SHTF, I figure I have about 45 minutes of battery to figure out where the ground is.

If it's VFR, I'll go do a couple more loops, two rolls, dance with a cloud, and then head back to the airport.
