Re: Looking for Instrument Instructor Who Knows Horizon HX E

Bob's advice is very good. I find that I leave my PFD set as usual and display the HSI on the MFD. That way the PFD display is as I normally see it. When I tried the split screen, I had to look to find stuff and the display gets pretty cluttered. Now I have my MFD Map page with just two screens avai...

Re: Attitude Issues

We had problems with the mag heading changing in flight. Didn't happen often and we couldn't make it happen on command. Eventually we relocated the magnetometer and that solved the problem. I think our problem was actually caused by radiation from the comm antenna. The new location is 10 - 12 feet f...

Re: aux input sensitivity

That should work fine. You probably won't need any filtering and I would try it first without any (always take the easy way first!). I used this amp for several years on a fuel pressure for my EIS. Do you know how to calculate Offset and Scale Factor? There is an article in the files section of the ...

Re: aux input sensitivity

Yes it is too small. 50mv is only 1% of 5 volts. So your input would vary less than 1% of expected input range. You may also find that there is noise in the aircraft that could be a significant factor - it may be as much or more than your signal. Two possible solutions. You can put a amplifier on th...

Misc Questions

Investigating another problem the other day, I measured the regulated 12 volt output of my EIS (red/green wire). It measured 10.5 volts when the battery buss (power to EIS) was 12.5. Is this normal? Shouldn't it be close to 12 volts? I ocassionally see variation in fuel flow which I don't understand...

Display

I've noticed that when I select "Set Limits" (pushing the left and center button simultaneously), the display goes into a reverse mode. In other words, the characters become a light character on a dark background. I think EIS stays in this mode until powered off and back on again. The disp...

XM Weather weight

Does anyone know how much the GRT XM WX processor and WXWorx receiver combination weighs? I'm considering relocating for CG reasons and need the weight which I can't seem to find in my documentation or on the website.

Thanks

Re: HSI Background

One other trick Carlos showed me. When flying an ILS, once you have the needles centered, keep the flight path marker on the airport. This makes compensating for wind easy and makes keeping the needles centered easy. Of course keeping the needles centered is the primary reference and requirement but...

Re: HSI Background

I flew some approaches with Carlos yesterday and have worked out a system that works well for me. I no longer change the PFD to split screen. I leave it as I usually have it so it is familiar and I know where to find information. I did add the ILS bars to the PFD but they only display when a ILS is ...

Re: Installation of GRT Autopilot

Bob, I believe the GRT servos are similar size and mounting as Tru Track servos. Here is a link to how to mount Tru Track sevos in a Zodiac http://www.trutrakflightsystems.com/documents/ZodiacPitchandRoll.pdf Likewise, there are pretty good manuals on check out of autopilot functions on the Trutrack...
