Joe Larussa Posted January 16, 2018 Report Posted January 16, 2018 Anybody out there install the GMU 11 to go with their G5? How did it go? Cost and is it awesome? Quote
N201MKTurbo Posted January 16, 2018 Report Posted January 16, 2018 Put it in the right wing. It is awesome. I used it to swing the magnetic compass. It is dead nuts all the time. Quote

Mine is wired to the 530. The GMU 11 is just the magnetometer. If you hook up a GAD 29 and connect it to something that puts out the correct AIRINC data. You get an awesome HSI! Quote
kortopates Posted January 16, 2018 Report Posted January 16, 2018 So do you need both? Both for what?Sent from my iPhone using Tapatalk Quote
Hector Posted January 16, 2018 Report Posted January 16, 2018 I think you will need both with dual G5’s with one of them as an HSI and you want to use the AP in heading mode. Without it you will only have GPS track mode. Sent from my iPad using Tapatalk Quote
Joe Larussa Posted January 16, 2018 Author Report Posted January 16, 2018 I would like to see the localizer and glideslope. Already have an HSI. Quote

N201MKTurbo Posted January 16, 2018 Report Posted January 16, 2018 Are you saying that you want to see the localizer and glideslope on the G5 PFD? I installed mine as an HSI but I have flown it in PFD mode and it does show your heading, the localizer and glideslope Quote
BDPetersen Posted January 16, 2018 Report Posted January 16, 2018 I’m just finishing GMU-11 install for my G5 AI. In my C model I opted for a tail cone location. I ran into a snag in the magnetic interference test from the rotating beacon causing interference . I had a Grimes “coffee grinder” which I elected to replace with a Whelen led flasher. To my surprise, it caused a problem as well. It turns out the problem came from the unit being grounded to the adjacent airframe. Running a ground back to the battery resolved the issue. Waiting for a warmer day to finish the compass calibration. Quote
Browncbr1 Posted January 16, 2018 Report Posted January 16, 2018 I have mine installed in the tail way up high where a previously installed electric magnetic compass sat. It works well. I was flying an ILS yesterday (vloc on the gtn/G5) and the GS didn’t appear until about 3.5 miles from the runway, so there is something going on there than needs to be addressed, but all other things are great. The gtn automatically turns the HSI course needle to the final approach course for the ILS. Quote
ArtVandelay Posted January 16, 2018 Report Posted January 16, 2018 Put it in the right wing. It is awesome. I used it to swing the magnetic compass. It is dead nuts all the time. I replaced the old NSD 360 unit which was mounted on a shelf in the tail. No issues. Quote
MIm20c Posted January 16, 2018 Report Posted January 16, 2018 I think the OP is asking if only one G5 is used with the GAD 29 that the display is able to show the LOC and GS info. I’m also curious for using the unit as a secondary for that purpose. Quote

I have a GAD29 I will sell you cheap. I replaced it with a GAD 29B for the autopilot interface. The GMU11 was only $150 or so, so the install will be the big expense and it isn't hard to install. If you put it in the wing you can fish the wire through by taking off the belly panels and the threshold plate on the door so you can pull the interior panel back a bit to stick your arm down in there. If you put it in the tail you have to take half the interior out to fish the wire through. Quote

bradp Posted January 17, 2018 Report Posted January 17, 2018 If folks are installing the GMU-11 in the wing mind taking a picture of the mounting bracket? I’ve seen a shelf in the tail picture but not a wing yet. Also where in the wing (how far outboard / at what Station) did you mount it? Thanks ! Quote
ArtVandelay Posted January 17, 2018 Report Posted January 17, 2018 If you have electric speed brakes, you probably won’t have desired clearance from motors required if locating it the wing. Quote
kortopates Posted January 17, 2018 Report Posted January 17, 2018 If you have electric speed brakes, you probably won’t have desired clearance from motors required if locating it the wing. Shouldn't be a problem. Mooney has been always been installing the magnetometer in the wing. They install them on the left wing same area but opposite wing of where the AP aileron trim servo is installed. Speed brakes are further inboard where long range fuel tanks are or would be.Sent from my iPhone using Tapatalk Quote
