A back up is always good, most home built aircraft don?t need a a ILS receiver as a back up. A simple VOR should be enough. Only if you are planning on routinely flying to 200/1/2 would a ILS backup make sense. Again cost and complexity have a big say. You could put in a 375 and a 650 and be well backed up.

Default Back up ILS

A side note.Most LPV approach minimums are higher than an ILS DA or DH. Having said that we're talking 300' vs 200'. Still pretty darn low.

Emphasis on FULLY charged. Not something I fully appreciated. I'll spare everyone a repeat of my saga.

Have any of you actually flown an ILS approach on the portable Navcom radios?
Just wondering....

Oh my. It is foolish to call other people foolish.

That was a real question. Not making judgements at all.

Yes. I'd say it was like bringing a .22 to a gunfight: not perfect gear for the job, but vastly better than nothing.

Meanwhile, I've flown a non-precision GPS approach with a Garmin G5 and an iPad running Foreflight. Obviously that combo isn't legal for IFR, but it's very very functional in a pinch, probably easier than using a 430.

The 430 is miles ahead of an iPad in terms of reliability, obviously. My 430 has never crashed on me once. My iPad definitely likes to take a nap every now and then.

Had VOR/GS/LOC/MB in my old RV-4. I flew IFR rarely. It came in handy a few times for IFR departure to VFR or IFR letdown through under-cast. No GPS approaches or area navigation, e.g., ATC go direct to a way point that you cant track to with your VOR, you can't accept. You could decline direct waypoint clearance and ask for vectors. In certified planes I used a handheld GPS as secondary situational awareness flying NDB approaches.

Commuted for years in a Tomahawk with only VOR/LOC and MB. VOR approach was all timed, VOR on the field. LOC had MB at FAF. If it was low I did not go... This was before IFR GPS were available. Now most NDB/LOC and MB have gone bye bye for GPS approaches. GPS is far better of course. However ILS is still the mac-daddy of approaches, can get you to 200 HAT and 1/2 mile or 2400 RVR and pretty commonly available. That is low, However GPS with WAAS can now achieve it. Not that common yet, and GPS LVA does not give your vertical guidance, so it's not really percussion. (Correct me if I am wrong)

I may not go IFR on current project. I'm sure some folks are flying IFR with non certified GPS.... don't do it. My bottom line are you really going to fly IFR? I suggest put in previsions and add later. BY ALL MEANS have attitude instrument flying instruments and PRACTICE using them (with safety pilot and hood).

Now many RV's have one or two axis autopilots as a norm. Those will save your bacon, and I say almost mandatory for safe SINGLE PILOT IFR... Hand flying an RV in clouds single pilot can be a handful. If you get in an unusual attitude it will WIND UP FAST!!! Not good IMC. You are adding $10K or more to your panel to get IFR GPS and Autopilot... How much will you use it? My guess is not $10K worth. It is up to you and of course if not equip you will have much higher mins to fly to avoid IMC. If you fly local you can stay on ground. If you go XC a lot, a special VFR departure may get your travel day started early.

.
I recall when aviation gps?s came out. All you needed was a good ground track, and suddenly you could fly NDB approaches to right over the runway with any piece of sxxx ADF. Of course the gps was for position awareness only

I haven?t done a survey, but I?ll bet nearly every runway in the US with an ILS now has a GPS LPV approach, with most of them down to 200 and 1/2. Then there are lots of gps approaches at runways without an ILS, with slightly higher minimums due to the need to see the runway environment where there is usually not an approach light system.
LPV approaches do have vertical nav guidance.

I agree. And I don't think this is limited to RVs.
