Default IFR Requirements

Hi All,

I'm a VFR pilot asking an IFR question.

I'm going with a full Skyview system with dual 10" displays in my RV-7A. What additional equipment would I need or would you recommend for making my bird good/safe/legal for flying Instruments? I've also got the Dynon Heated pitot which I see has a new service bulletin.

As always - thanks for the valuable input!

What are you using for nav/comms? GPS?

It may not be 100% Complete, but it helped me memorize the key points.
IMHO, I would also add if you can afford it, duplicate as much as you can.
You may only get one chance to save your .... well you know.
(It can get nasty up there)
I have this in PDF form and downloaded it to my foreflight documents for easy reference.

That is a non-W 430; b/up batts in the SV and D6. I also carry a handheld comm (belt and suspenders). If I was building my panel today, I would be using a 650W for sure. Honestly, the level of capability available to experimental aviation is incredible - especially when I think back to finger to low altitude chart, plates strapped to my leg, and watching my RMI needle bounce back and forth 45' either side of center outbound on an NDB approach.

Without getting into personal opinion about IFR in ASEL, etc, you already have awesome capability with SV (dual 10" to boot). I would add a second comm for sure, a reliable backup AI, then the nav source. Even though it is $$, I don't think the 650 can be beat. You then have one of your comms and ILS capability. Add Dynon's new control heads and you have an A/C with remarkable functionality. I am truly glad I learned to fly instruments with steam because the glass SA is just really simple in comparison - just my opinion.

There is no one correct answer. All flying involves risk. With ifr flying, you add the risk of flight instrument and/or radio navigation failure.
For some pilots, they are willing to accept the risk of flying with the bare minimum equipment. Others will settle for nothing less than triple redundancy everywhere, including dual alternators and batteries. Most are somewhere in between. For myself, I would not feel comfortable without a second set of flight instruments completely independent, including software, of the first set. So I have a D6 to back up the GRT HX, HS. Also a Trio autopilot. But I did not put in a second (E buss) electrical system, so my worse case scenario is a direct short to the primary buss, taking out the alternator and battery. I'm then left with the D6 and its two hour backup battery, and handheld VOR and handheld GPS, to find an airport within 2 hours.

A few corrections to the required equipment post:
First, for EAB aircraft, nothing is required for day-vfr flight. Assuming your op limitations are the standard "night and ifr authorized if you follow far 91.205" then the day list applies, too, for night or ifr operations.
MP, OAT, and landing light are not required, although it is standard practice to have MP with CS prop installations.
Slip-skid is not a gyro.

Ken, Nice list!

I always liked this one since I was in the northeast and ATC would spit out a clearance at warp speed!

C ? Cleared to
R ? Route
A ? Altitude
F ? Frequency
T ? Transponder code

To Ben, the OP of this thread. All the replies have been good. I have just gone through this process the last two or three years and just passed my biannual IFR check ride. Before doing any IFR work I had completely different thoughts as to what equipment would be required. I would suggest that you get some IFR training with an instructor, in actual IMC conditions. This will give you a much greater appreciation for what is required and what your personal comfort levels are. My personal IFR limits are a lot different then I thought they would be prior to sticking my head in the clouds. It is serious business and before you spend any money on equipment get some training.

When I learned to fly instruments we had one VOR and an ADF. Everyone thought that was just fine. Now it seems like you need dual GPS. I am not recommending going back to the old ways, but getting some time with an instructor is great advice. Even if it is only a couple of flights. You will least get exposure to the system and will have a better perspective to make your decision.

I am building an IFR aircraft, but I have no plans on flying all day in the crud with my RV-7. IFR departure and maybe arrival if the minimums are high enough.

I am also a VFR pilot. I have been told/am under the impression that some "certified" equipment is an FAA requirement for IFR flight, particularly a GPS unit. Neither the Dynon nor the GRT glass panels qualify even if you have dual screens and dual gps units by these manufacturers. Is this notion correct?
