Dream Panel

This is pretty much what I'm planning for my new ship. A few (probably stupid) questions for you: 1) What is the smallest battery that the LX V3 would have? 2) Why both the V80 and the Butterfly Vario? Can't the V80 do everything that the Butterfly can do? 3) Any idea if all that would all that fit in a JS1's panel? By my reckoning, with the jet control unit taking up one slot then there wouldn't be enough space for both the V80 and the Butterfly but that's a guess.

Regarding JS1 panel, in my opinion if you stick with LXNAV 9000 (V8 and not V80), all 2.25 instruments, and Trig radio and transponder tightly "stacked" or the yet to be released Air Avionics Air Com there is enough room. One 2.25 instrument will have to go under the panel in the raised floor pan instrument area. That instrument should be a "look only" instrument such as an altimeter or compass.

Redundancy is the reason for the LXNAV 9000/V8 and Air Avionics Butterfly and they should have no common plumbing including probes.

PM me your email address and I'll send you a paper "mock-up" picture.

The LXV3 has a battery pack UPS you can buy with it that will power the instrument with full audio for 8 hours or more. That is the pack I would use.
As for why Butterfly and LX 90XX with V8, in one instrument you have a back up vario with audio, speed to fly, instatainious wind, navigation, final glide, Flarm display, Flarm radar, data logger, horizon and perhaps a few others I am missing. Not cheap but then the question was "dream panel".

A "Memphis" variometer.

What is a Memphis variometer?

Burt,

More accurately it's a Memphis rate of climb. And I still have one! Once in a while I think about popping it into the panel but I don't have room. You're the first person to mention a Memphis in at least 20 years.

Chip, you are correct. Like many sons of the fifties and sixties soaring pilots, I have a couple of classic "Memphis" rate of climb indicators. One is still working fine in my late father's Open Cirrus sailplane here at Marfa. A prized instrument in its time and sought after by vintage sailplane restorers. For the "newbies", see the SSA "American Soaring Handbook", Chapter 7, page 18. Yes, it's out of print but a valuable resource and in some ways better than the current FAA Glider Flying Handbook as the ASH chapter topics were written by soaring pilots, not by non-pilot FAA "technical writers."

History lesson (Burt, correct me where appropriate; my memory is a little hazy this far back): My father also had two Memphis ROCs. The second one he found in the 60s in a V-tail Bonanza in the small town in Alabama where he had grown up. [I don't know where the Memphis instruments--referred to, I believe, because the manufacturer (Aircraft Indicators?) was located in that city--were installed but the early Bonanzas were a common location] He persuaded the owner to let him swap the Memphis for a brand new Kollsman ROC and she was happy to.

A club member in the Soaring Society of Dayton (predecessor of Caesar Creek) named Bill Coverdale (brother, IIRC, of Miles Coverdale, who was active in the SSA) quickly removed what he referred to as the "chokes" (restrictors) and, voila, a self-contained, sensitive rate of climb. The Memphis was the backup in many competition cockpits in those days.

Yes Chip, that sounds right. Beech installed them in many Bonanza airplanes in the fifties. Back then, Bill Coverdale would bring his bright blue Ka-6 to my Dad's gliderport south of Miami, FLA, in the winter. He wrote an article, actually a letter to the editor as I recall, in SOARING about removing the restrictor from a "Memphis." A search of the magazine archives may be worthwhile to anyone interested.

His brother Miles Coverdale (often sporting a big bow tie) wrote many articles primarily on training and safety and was the "grandfather" perhaps of our current Soaring Safety Foundation, of which I am Trustee (which in the southern states, means a trusted prisoner!)

Like you and your Dad, I was lucky to meet, through my father Fritz Compton, many of the legends of soaring from that golden age and listen to the discussions of "how to" which they shared willingly at the single national "open" contest or at one of the regional events each summer.

Many years ago there was a Heads Up Display offered for sale. Have never even seen these on the secondary market. Would be nice to have a HUD with vario, farm and airspeed info. Maybe if it had compass info a mechanical compass would not be required instrumentation. Just a thought. LX Nav want to make another option to go with the LX 90XX computers?

Was wondering what would be your dream panel if cost was not a factor and why you would choose the instruments you do?

Firstly it would be inside of a KA-6e, and made of varnished birdseye maple, with a pellet vario, and ivory-faced, anodized aluminum instruments

like this:

No GPS, no electronics, other than maybe an audio vario that wouldn't ruin "the feel", and of course a radio. especially one that looks vintage.
