I just came out of a great annual with a meticulous mechanic and was a happy camper with a great report card on the Toga. This afternoon after the weather cleared I was able to take it up for the first post annual fight. It was VFR and I was doing a visual RNAV back to my home and I looked down at the NSD 360 HSI and was baffled that the heading didnt match. I was throughly confused and it was CAVU out the windscreen. Truly an eye opener for a real deal instrument failure during IMC. The fact that the instrument had died and was wrong was not the first thing to pop in my head.
Anyway, all functions of the HSI still worked except the DG portion wouldnt spin. The needles would move fine and the glideslope, etc. operated fine despite a fixed heading displayed.
So after pulling it into the hangar I just sat there about to cry thinking about how Id hoped that thing would keep breathing until the Dynon skyview became available. I didnt want to fix this old mechanical one and I dont want to drop a bunch of money on a G5 if Im thinking bigger glass in the next couple years.
Then the obvious solution slapped me right in the face... I already have a Garmin G5 in the panel as my backup AI. It sits in the T/C slot. The quickest and easiest solution (I think) will be to move the G5 one hole to the right into the HSI. I believe all Id have to add would be the remote magnetometer to make this work. Then to be legal Id have to put my T/C back into its original home. Fortunately I saved it when I put it in the G5.
Im saying all this to ask if this is my best solution. I really need something reasonably quick and simple as I am super anxious to get to my IFR checkride and I dont need a multi week setback at an Avionics shop. I think the G5 move / magnetometer addition would be a quick change?
I realize I lose my backup AI by making the G5 my HSI... but I did that panel change before adding the IFD 550 so I have no worries about a backup AI any longer.
What say you all?
