Just the ground calibration, the D100 with the EDC-10A does not have to perform the in-flight procedure according to the D10A manual

Did the calibration, the calculated magvar initial position numbers for my current location (Tulsa OK) were quite different from the existing numbers in the D100 but I have not touched those since I finished the plane in 2008 (in Salt Lake City). NESW setup was quick. Only question is I did not...

I have the typical D100/D120 setup with the D10A and the OAT. The system is coupled to GPS (GNX375 and Aera 760) via the HS34 (both serial and Arinc429). For some reason the calculated wind component at altitude (as shown on the HSI) has never appeared to be correct either in magnitude or...

What information does the D-100/HS34 pass to the 175/375 over the arinc 429? Does it include the altitude encoder data or does that still need to connected over RS 232 from the D-100 to the navigator? Also does the OAT data go to the 175/375?

Thanks for the reply very helpful, in my case I have the aera 760 on pin 1 of the male DB25 on the HS 34 and the SL30 on pins 2 & 15. If I connect the 175 via the 429 then I believe I would be able to cycle the HSI between the 175, the 760, and the SL30 nav sources. The 760 is also connected to...

I assume on the 175 to HS34 drawing that the RS 232 to the autopilot is a backup in case the 429 has an issue is that correct? I also assume I could connect that RS232 to a switch that could switch the input to the TT AP between the 175 and my 760 in the event that the 175 had a problem. What...

System has been working well since 2008 but recently my altitude readout  has been off by about 100 feet from my flying buddies (at the same baro setting). I read the ALTADJ section in the manual but it does not say specifically how to do this, do I set 29.92 with the HS34 and adjust the reading...

My D-100 has worked flawlessly for almost 3 years but when flying back from Oshkosh the display started to show horizontal noise like patterns reminiscent of raster scan lines. The lines also appeared related to the display driver as they appeared to map to each screen in split screen mode. I...

As an update I finally got the process to work and for info this is what I found. There appears to be a conflict with the prolific USB to serial drivers with the 5.2 release if there are other comm ports in use. In my case I had comm drivers installed to allow my laptop and netbook to tether to...

Trying to update my systems (D100, D120, HS34) to version 5.2 from 5. Using a netbook running XP with SP3 and the prolific USB to serial driver. This all worked fine in the past for the updates but on 5.2 when I start the support program I get the message that the device is found on com 3 but...

Thanks for the response

Any way to keep the heading bug on the tape but not have the numerical readout on the lower right?

I am running version 5.0 on my D100, D120 and HS34 with no apparent problems, I noticed that the latest version on the web site is 5.0.2 however when I tried to update the system it said that the version was already installed and did I want to reinstall. I said no and re-checked the  installed...

Recalibrated the tank senders in flight attitude and they are working much better, also reset the Tach as suggested and this is working now. Thanks for the support

Tried a couple more tests yesterday, went to HSI setup and selected the various AoA alarm choices in turn: EXT Voice..test function worked "STALL", annunciation occurred after the stall break after the top flashing red chevron EXT Tone ..same result as above EFIS Tone ..no tone from the test...

I sent the backup files, any update?

Top of triangle was flashing and the chevron indicator seemed to be working fine (green to yellow to red then stall) I will get backups tomorrow and email them to you

I should also add that I also tried recalibrating the AoA and had no change in the alarm behavior

I just updated my D100, D120 and HS34 yesterday to release 5.0 and today decided to check out the new stall voice warning function. There appears to be a problem now with the upgrade as neither the voice or the tone alert occurs until about a second after the stall break (top of the red...

In my RV-7 I installed the oil pressure sender switch with circuit normally closed, this lights a master caution light on the panel. When the oil pressure is greater than 15 psi the switch changes to NO and the light goes off, the other side of the switch now controls the hobbs. In the NC side I...
