REFLECTOR:GRT EIS

For those of you who haven't purchased a system yet, I can highly recommend
the highly functional, very useful, and excellent value Grand Rapids
Technologies EIS http://www.grtavionics.com/ - and if you must have a color
display he has that too - or will soon.  Support from GRT is excellent!

I had originally considered the VM but decided to save the panel space and
$$$ and chose the EIS.  It isn't as "sexy" looking, but considering
everything, I made the right choice FOR ME.

I have been flying for 6 months and have 90 hours on my Velocity.  My EIS
4000 has worked flawlessly, takes up little valuable panel space and is my
super highly intelligent IDIOT LIGHT.  It monitors everything, limits can be
set on anything - high, low, rate, etc as needed.  I don't have to monitor
anything - except when setting engine RPM and monitoring EGT when leaning.
Any alarms trip a master alarm light then I look at the EIS and the
parameter in alarm is flashing.  EASY!  I have fuel flow, fuel pressure,
MAP, header tank level, for my optional inputs. And during my flight
testing, I hooked my Laptop to it and recorded all of my engine temps,
flows, pressures, every second. Love it!

| I also have the same setup Chuck has, VM with the VM-1000, fuel gages,
OAT-CHT and clock.
|
| I won't repeat Chucks comments but I will heartily second them and add a
few comments to them. The lack of interconnection between my vision fuel
gages  and the vision system is really irritating.  Makes the fuel warning
system a joke.  My clock is always set to flight time, because its a pain to
change it, the interface is clumsy too. I have a countdown timer in my Terra
Nav unit that is simple and easy to use. I never use the vision clock for a
timer.
|
| in addition.
|
| 1.)  The inflexibility of the settings is frustrating.  Not being able to
set the warning values for Low Voltage, or High RPM or any other the others
is a big negative in my opinion.  I called VM and they said oh just send it
in , pay a whopping engineering fee for custom settings and your good to go!
So my plane has to be down for weeks and I have to pay a huge amount just to
have my Low Voltage warning come on 1/2 a volt lower than the factory
setting.  I should be able to set individual parameters myself in the
plane..
|
| 2.) Not being able to suppress a warning makes you ignore them.  If Low
Voltage comes on I don't want it flashing in my face for an hour or two if I
decide I can make it home on battery power.  I should be able to suppress
the warning for a few minutes or for the rest of the flight. I put tape over
the VM1000 on one flight because of just that.  Having a red flashing
warning that your are completely aware of for two hours is useless and
distracting.  So I covered it up and sacrificed all the other warnings
because of a lame interface that was interfering with flight ops.
|
| 3.) The 100 or so individual connectors to the sensors is a joke.  30's
technology.
|
| 4.) The visibility of the unit in high light conditions is very poor. When
flying into the sun its completely unreadable even with the back lighting
turned way up.
|
| As I said before, I would probably not install a VM in a new plane. I
think there are comparable units available that address all the shortcomings
for a comparable or better price. Its a very cool looking unit, one of the
coolest in my opinion, gets lots of ooh's and ah's when people see it, but
it falls short on the operating side.
