I am about to purchase the avionics for my RV-7 and I have one last
point of confusion. Any advise would be greatly appreciated.
I live in the Los Angeles area where there is frequently a thin
marine layer that traps VFR aircraft. My mission objective is to have
light IFR capability in the plane to be able to penetrate this layer
when necessary.
I am not currently IFR licensed but plan to get this after my plane
is flying (so I don't know much about IFR requirements at this point).
I am looking at using UPS (Apollo) radios. I think I would like to
upgrade the stack to include an MX-20 Multi Function Display in the
future.
Should I buy the SL60 GPS/Comm now (for later use with the MX-20
display)?. With the later addition of the MX-20 display, does this
make for light IFR capability using a GPS approach? Do I still need
the VOR/GS/LOC on top of the GPS and display?
Or should I use the SL30 Nav/Comm w/VOR/GS/LOC at the initial
installation with the CDI indicator? Will this give me light IFR
capability right away?
Thanks in advance,
Robert Paisley

Yes, the SL-30 with external CDI head will give you IFR
capabilities. For the rest of the list of required equipment see the
FAR's part 91.205

Hi, Robert,
Torrance was my home airport for decades, IFR lite. I'm planning for
the same type of mission in my RV-7, popping through status decks, no
heavy mixed icing in precip over the Cascades (I moved to Boise),
thank you.
I'm going the Apollo 30 route because you will instantly be IFR
legal. Forever, too, as long as you check that VOR within 30 days
(Yeah, sure.), plus the biannual pitot/transponder cert. Vertical
guidance from the GS makes ILS minimums far lower than GPS. You must
hassle maintaining the GPS database (which is not a trivial
expense). No big screen TVs required to see how you're doing on the
approach when you have steam gauges. I'm going to stuff a Garmin 196
into the stack, but for information only (wink). Far greater
flexibility and legal, without boxing yourself in with just GPS IFR
capabilities. Also, I think you need a TSO'd box ($$$) and it's a
more complex installation; a handheld won't pass muster. Could be
wrong here.
I mulled the need for a marker beacon. Best reading I get from a
variety of knowledgable, authoritative sources is that you don't have
to have one aboard to shoot an ILS as along as there is a substitute
for the OM (radar, vor, compass locator, etc.,). But there really is
no substitute for the MM except radar, but coverage is iffy and
that's at decision height, so relying on radar substitute is not good
practice. I've yet to fly to minimums before going visual, so I'm
not installing a MBR, but King does make a stand alone unit (21, 16?)
so you don't need to buy a pricey audio panel with a MBR built in if
you want a MBR.
Read the equipment requirements in part 91 and the IFR nav sections
of the AIM. That's what the DAR references before he hands you the
airworthiness cert for an IFR ship.
BTW, I'm going all electric. No more suck pumps and whirling magnets.

DimpleMaster -
Great minds think alike. I also have the SL30 and Garmin 196. I
recently
looked at the MB. Worse case, I'll by the MB kit and build it myself.
