Hi Dave,
I believe you are correct - you can fly VFR with any old
expired data you want, since you are supposed to be relying
your eyes for navigation, not the GPS. I have a Garmin 295
handheld, and I update the database once per year, for what it
is worth. At any rate I believe you are legal as-is, as long
as you are carrying current VFR charts with you.

Dj,
Not to heist the thread, but how do you like the 295? I'm considering
one and was wondering if there are any problems I should be aware of.
Thanks,
Jeff

--> Avionics-List message posted by: "GMC" <gmcnutt@uniserve.com>
Re GPS Updates.
My Understanding is that you require a current database to do a GPS approach
(IFR) and that the approach must be retrieved from that GPS database. No
build your own.
For IFR enroute and terminal operations the GPS database does not have to be
current provided that you verify each fix using a current date source.
For VFR use I am not aware of any rules regarding GPS database currency.
Ok now let me get up on my soapbox and rant! - The charges for updating
databases and Government publications are one of the biggest unnecessary rip
off's in aviation. It is cheaper to buy a second VOR or ADF than keeping the
GPS IFR legal.
And why do maps/charts, publications and databases need to be updated every
28 days, or 56 days with mid term correction. Most of the changes in
databases & publication here in Canada are things like government office
telephone numbers, heading change of 1-2 degrees (variation change),
altitude changes (runway resurveyed and now 2 feet higher shorter/longer)
etc, etc. And believe it or not many of the changes are to correct the
errors they introduced doing the previous revision.
There is absolutely no reason why all major changes (frequencies, airways,
waypoints) could not be planned to take place with a quarterly, or even
longer, revision cycle. Important stuff is handled with Notams.
Rant over - feeling much better now!

I consider it one of the best aviation investments I ever made.
I've had it for over 3 years, and find it to be an excellent tool.
The screen is very easy to read, and I think the color screen
is a huge benefit to the clarity.
The only limitation I can think of is that it
is rather bulky if you want a yoke mounted GPS.
I have mine mounted on a RAM mount attached to the
panel, so that is not a factor for me (experimental aircraft).
You could also use one of the window suction mounts
as an alternative if you have a certified craft.

Jeff -
I've owned the 195, 295 and 196. The 196 is be-far the best IMO. Faster,
more features, and frugal with batteries. I don't miss the color of the
295 at all.

Hi George,
I feel the same way about the expense of the IFR GPS updates.
I have read recently (can't locate the reference) that the
FAA is going to be releasing "free" data to the GPS companies
to use so that the cost of the updates will decrease dramatically.
Apparently part of the expense now is that the private companies
are the ones keeping the databases up-to-date.
I don't recall when this is going to happen, but I seem to
remember that it is not far off (within a year or so).
Maybe we can find out more at Sun-n-Fun or Airventure.

The 196 is also much smaller/lighter than the 295, and more
suitable for yoke mounting, IMHO.
But I think I would miss the color... *grin*

I have had a 295 since they where introduced, It is a excellent machine
except for the run on batteries,but if you run it from the aircraft supply
then that isn't a problem,
Likewise i do the update once a year at the start of the flying season and
keep up to date charts on board,

Thanks for all the replies. I'll be running primarily from A/C power,
so I don't think batteries will be a problem. Also, it will probably be
mounted atop the "dash". I've heard great things about both the 196 and
the 295, but think the color would be nice. Oh well, I'll make the
decision when I decide to lay down the bucks. Thanks again...

| Subject: | ICOM A200 Questions |
--> Avionics-List message posted by: "Troy Scott" <tscott1217@bellsouth.net>
Gentlemen,
About the ICOM A200:
1. WRT the three auxiliary audio inputs, does the volume control of the A200
affect the level of whatever auxiliary audio I'm playing through the A200?
For example, If I run the marker beacon audio through one of these auxiliary
inputs and I have the volume of the A200 turned all the way down, will I
hear the marker?
2. What happens with the auxiliary audio inputs when the A200 is turned off
completely? Would the marker (or whatever) still "play through"?
3. I'm assuming there must be audio isolation in the A200...?
4. WRT the transmit/receive interlock requirement, the ICOM instructions
tell me how to interconnect two A200s. If I use this A200 with, for
example, an Apollo SL30 or SL40, will I still have to accomplish the
transmit/receive interlock?
Regards,
Troy Scott

I'd recommend checking them out side by side
at Sun-n-Fun or Airventure or similar.

Gentlemen,
What's the consensus on an antenna for the ELT in my Glasair? Should I
install a dedicated copper foil dipole? Should I just use the portable
floppy antenna that came with it?

Gentlemen,
Where can I get a good deal on the Honeywell/Microswitch 45/59 series
solid-state (LED lit) annunciator lights like the ones Vision MicroSystems
used to sell? Lancair Avionics has them, but they want $38 for the
annunciator/lens unit. That seems a little steep. I want 10 (maybe 16) of
them. Here is a link to what I want:
http://content.honeywell.com/sensing/prodinfo/pki/catalog/aml45_59.pdf
Also, If any of you have a suggestion for a good substitute, I'd like to
hear about it! I already know about the panels from Aircraft Simulators.
Regards,
Troy Scott

I don't know what you consider not "steep", but try
http://www.onlinecomponents.com/
The ones listed there seem to be about $24 for 1-9 and $21 for 10-24.
Don't know which ones you want. Some are in stock, some are available
with 8 week delivery and others are not listed.
Depending on how clever you are you could also make something that would
be equivalent by using the LED indicators listed in (I don't remember
where, but I have it at work - so stay tuned tomorrow)...
Good luck.
