I have the BM EFIS one and Lite installed in my aircraft and I am glad I
chose BM for my installation.  Dave Bertram

I forgot to mention this (not sure why this would slip my mind), but I put ½
of my money down on the BM at Oshkosh ’04 and I am (cross your fingers
please) suppose to be getting mine next week or the week after.  It really
hasn’t been an issue since we didn’t need the box right away.  It’s starting
to become an issue only because we need the AP servos to mount.  There have
been more “vocal” people on the BM website that order there’s much later
(Oct) and have gotten there’s sooner.  Squeaky wheel gets the grease.  But
I’m sympathetic of the “small guy” and sticking it out.  Plus I feel this is
a one time delay and the feature set it worth.

Have any of you guys considered Blue Mountain Avionics?  They have had
growing pains 
 but I really believe the value is unbelievable and the
system works.  I am flying it now.

Keith,

I think you'll like the setup.  GRT was going through the usual growing
pains but they seemed to have gotten out of the gate and up to near full
speed at least as well as, if not better then BMA.  I do wish they would
finish up their ARINC 429 software so the vertical bug would drive the
TruTrak A/P.  I suspect they are being particularly careful about the
vertical commands being bullet-proof.  Something about commanding the plane
to descend to a lower preset altitude at a predetermined descent rate in IFR
conditions has a smell of liability associated with it.

Steinair seems to be a safe choice.  He seems to be present/participates on
both the RVList and AeroConnection websites and no one seems to throw
brickbats at him.  Some of the things he posts even makes sense...which puts
him ahead of many, if not most.

I think you'll be happy with you choice.  If I were to make the decision
again, I'd do the same (though not at the same place).

Chuck

Chuck,

I agree on the big map display.  As I wrote, I'm planning to use the upper
for PFD, lower for moving map.  I had planned to swap out the moving map
display for the graphical engine display at those times when I want to look
with more detail at engine parameters than the display on the EIS provides. 
However, the split screen on the upper is a pretty good idea.

I just got a quote from Stein Bruch (www.steinair.com) on a dual display GRT
EFIS & EIS system for my Velocity.  He basically confirmed that you have to
use two multi-function displays.  The good news is that my configuration
(including fuel gauges, fuel flow transducer, pressure transducers,
thermocouples, OAT, etc.)  came out $435 less than GRT's list prices, and
includes free wiring harnesses!

Keith,

I pretty much dedicate the bottom display to the engine data because I take
my map stuff off the Garmin 480/MX20 combo.  But if you use the lower
display for the map, then you can do the split screen on the upper and
display the PFD left and major engine data (RPM/MP etc) on the right.  The
PFD, even on the split screen, is still plenty big to show you a good
horizon, airspeed and altitude.  When I've played around with the map
function on the GRT EFIS, I didn't care for the map function on the split
screen.  Maps are all about context, hence the map on a split screen is like
trying to drive a car looking through binoculars.....okay, so you've never
been stupid enough to try that, but you can know that it's not easy because
you loose reference to the surroundings, which is what a map on a split
screen does.

In short, I don't see any advantage to a dedicated screen, unless there is
big $avings.

Thanks, Chuck.  I had planned to mount the EIS 6000 in the panel anyway, so
when I'm using the lower display for moving map full-screen I'll still have
the basic engine information displayed.

I had intended to use a "PFD only" dedicated display for the top, but l need
to confirm whether or not I can mix a multi-purpose display unit with a
single-purpose display.

Keith,
I have the dual GRT EFIS and both can be selected for PFD, MAP, ENG or split
screens.  I personally like the PFD on the top and all my engine stuff on
the bottom.  There is a soft-button that you can 'lock' either unit to PDF,
but I don't see any advantage.  The buttons are big enough that they are
easy to locate and push, even in turbulence and without the problem of
inadvertently hitting the next door neighbor (button).  I also have the EIS
6000 LCD screen mounted on the panel.  If it wasn't for infrequently
resetting some value, I wouldn't put it on the panel as it just eats up
space.  Unfortunately, when fuel is loaded, it is inputted thru the LCD unit
 not the EFIS, so you need access to the rectangular LCD computer unit--may
as well mount it.

What would be great would be if the EFIS and EIS talked both ways, so the
fuel could be added thru the EFIS screen, but I think the conversation only
goes one way--kind like some relationships.

Hmmm. .   I talked to the EFIS sales guy at Grand Rapids about my intent
about 5 months ago, and he said, "no problem".  I'll have to look into this
further.  Of course, my situation might be somewhat different because I'm
using their EIS 6000 for engine monitoring.  I agree that flexibility is
nice, but it also leads to more complexity.  Then there's the $500. . . .

I'm also planning to use the GRT EFIS.  At this point I'm planning a
dedicated PFD on top, with a multi-mode Moving Map/Graphical Engine Info/PFD
under it.  My thinking is that I will always want the primary flight
instruments right in front of me, but if that unit goes south, I can use the
lower GRT display as a backup.  The lower unit will usually be in moving map
mode, except during leaning or evaluating a potential engine issue.  The GRT
EIS 6000 will provide engine indications the rest of the time.  My backup
moving map will be the GPS (both panel-mount and handheld).

I have the dual screen GRT setup, and also intended one as dedicated display
since I have a separate engine monitor with will not display on their screen
  Apparently, you cannot have one dedicated and one not dedicated with the
two displays, and they charged me the extra $500.  When questioned, they
refunded $250.  I think it is good to be able to use either screen for any
display.
