New GRT Software Drop!
For those with GRT panels, they released the latest software drop today (if you haven't already heard)! Lots of new stuff - the maps now show roads, population centers, railroads, etc. Getting better for VFR, that's for sure! There have been tweaks to the autopilot steering laws, and some cool features I've wanted - for instance, you can now set the red line to be a "barber pole" like variable that shows you the IAS that corresponds to a TAS limit - since the flutter limit on RV's is based on TAS, that is really convenient for high speed descents! (Guys with rocketized RV's may want to ignore this....)
I loaded up the new releases this afternoon and headed out for a quick evaluation flight. Unfortunately, a thunderstorm popped up and I had to race home, not able to take any picture - those will come when I get the chance. There is also a new AHRS load, but I didn't take the time to upload it in to my units - I want to see if it fixes the heading errors we have seen crop up after three (plus) turns in the "Commercial Death Spiral" maneuver.
Once again, all this stuff is free, as it is from most of the experimental EFIS companies - how can you beat that!

Hey Paul, any idea if the new map functionality is compatible with the H1 hardware? I noted the various new databases on the support site, but info on the v34 upgrade for H1 (HWS) was sketchy.

Full coupled ILS approach in the NEW GRT software
The button pushing on an full ILS coupled approach (one needing course reversals etc.) using the info from a Garmin 430W has now been simplified. It works just like the ILS approach using vectors. Arm the approach, select GNAV, and sit back.
Alas, this is not the case with a GPS/ LPV approach. You still have to wait until established to ARM the approach.
If you arm it early, bad things happen. If you forget to arm it after getting established, the needles will appear but the autopilot is not coupled.
It works so much smoother now on the full ILS approach, I hope GRT will standardize the LPV approach also.
Again, GRT Avionics has done a good job! Thanks to all in Grand Rapids!

Bug fixed in new GRT software- ILS frequency in GNS 340W
 A l known "bug" in the GRT EFIS software has now been fixed. Before if an ILS/LOC frequency was loaded in the Garmin 430W, a GPS/LPV approach could not be loaded in the GRT EFIS. This has now been FIXED! Thanks GRT!
Now I still wish the turn and bank indicator moved in the direction of the bank...for us old guys who have been flying like that for 40+ years. When I bank to the right, I want to see the needle move to the right....I know this is not the way the bank indicators in the HEAVIES work....but I am flying a RV9 not a 747

Good news, Bad news
The bad news is that GRT pulled the new software because of a problem with the AHRS 33 part of the new load.
I downloaded and installed it before it was pulled. I installed the new software on my dual Horizon I (WS). The first thing I noticed is that the new map looks great (I run 1 screen in Map mode all the time). Private airports are now shown, so there were a ton of airports cluttering the screen. There are new map settings, I changed the "Show Small Airports" to 10 miles to remove the clutter. Anything greater then 10 was too cluttered.
I also installed the Water and Roads databases - looked great from what I could see without flying.
The new AHRS V33 gave me the leans, so I going to re-install V28.

Revision Control? Change Control? Release code reviews? Unfortunately these are some of the first things to fall prey to lean times and small teams.

I can't agree that lean times or small teams caused this ... I use to work for a large company with 100's of programmers, testers, and customer beta programs (RockwXXX). We still got product to market with Thurday (yes it was to be Thursday) in our entire software package. I took customers in the field to tell us we couldn't spell. That was after two years of development.
on the other hand GRT got it fixed in one day!

Yup - got home today from a day of flying at work, and saw the note about their mistake on the AHRS software. That was on top of their redo yesterday on the correct version. I'd rather they slow down a tiny bit in their excitement to get the new stuff out.....
Fortunately, I am MUCH slower to update my AHRS software than I am the Display software, and still had V28 loaded. I always keep the previous software load on a thumb drive in the cockpit, and generally stay about a rev behind on the AHRS.

Now that is an idea worth stealing
Great idea, wish I had thought of it.
