Default IFR Power Requirements

Ran across this thread and want to give it a "bump" because I am considering installing IFR capability in my RV12 and have some input on power usage.

I have an IFR RV6 with Skyview and normally power: 10" Skyview, GTN650, Dynon Com & Intercom, Dynon transponder, Dynon ADSB, Dynon D6 and Whelen Strobes. My recollection is that this draws about 9 amps in normal flight - higher when transmitting.

This equipment works well in the RV6 and I would do the same setup in the RV12, except probably a Dynon D1 instead of the D6.

If I turn on pitot heat, nav lights and my old fashioned dual automotive landing lights the amps go WAY up in the RV6 but I would have none of those in the RV12.

I would be interested in hearing from anyone on the forum operating their RV12 in IMC - how you have it equipped and how satisfactory it has been.

Just curious if anyone has done/is doing anything like this? If so, what equipment are you using?

Dynon: D1000, SV-XPNDR-261, SV-Knob, SV-AP-Panel, SV-ADS-B, GPS-250
Avidyne IFD540 with IFD100 on iPAD Mini4, Garmin GA35 WAAS antenna
Garmin GTR200
PS Eng PM3000 w/COMM1, COMM2, NAV switch (4P3T)
Dynon heated pitot/AOA in wing, NAV/ILS antenna on top of VS
ForeFlight 9.1.3 on iPAD Mini4 w/DUAL WAAS GPS
D1000, IFD540, and iPAD are all connected by WIFI/BT (synch ForeFlight FPs)
Dual batteries with A/B power buss (more for the dual ECU and fuel pumps, than avionics)

The IDF100 duplicates the IFD540 data and can be used as an additional display/control for the 540. Nice because you can setup the 540 for a FP/approach and use the 100 to look at/change other 540 data.

Setup hits about 35A with the pitot heat and lights on. Other items to keep in mind: IFD540 added 11 lbs to panel and depth pushes connector wiring within an inch of the firewall. A 3/4x3/4 AL angle was added to the F1202B panel base from the left to right longerons to handle the extra weight (originally also included the second battery in the map box area). The F1202J instrument rack brackets were replaced with a custom bracket that incorporates the F1202K bracket that works with the one-piece panel design. There is a lot of wire running down the tunnel to the tail cone, so plan ahead for snap bushings & holes.

What he said. In the end, you only need the navigation equipment required for the flight. In other words, you don't need a GPS unless your doing GPS approaches, and you don't need a WAAS GPS unless your doing RNAV approaches that require WAAS. You can get by with a simple NAV radio and do VOR approaches.

When you say "light IFR", I understand what you mean:

I took this photo this morning on the way in to work; it's a beautiful day, but with a cloud tops at 1800' and bases at 1,000'. I obviously suck at panoramic photos in flight, but you get the idea. To be certain, it's the same equipment requirement for "hard IFR".

In addition to the VFR equipment, you just need the 9 items listed in 91.205. For an experimental airplane, unless it's prohibited in your Operating Limitations for some crazy reason, be rated and current as PIC and go fly; that's it.

Now, you can go crazy, like some nut I know personally, but it's not required:

Small clarification: The FARs restrict EAB to Day-VFR. What you're looking for in your Op Limits is a waiver, allowing IFR if equipped per 91.205.

It is a nuance, but an important one. The FAR Bob is referring to is 91.319.d.2; As long as you are smart about your operating limitations, it should refer to FAA Order 8130.2H, Appendix C, paragraph 41 allowing VFR day, night, and IFR operations. I'd also ask for para 46, operations over populated areas.

...and then just be current and properly equipped for the flight.
