I found the cowl flap thing. It is in the CAR-3 and part 23 certification standards. So, the mooney would be required to have a CHT gauge.

Apparently, it is not required. https://www.law.cornell.edu/cfr/text/14/91.205 If it is listed in the type certificate then it will require an STC to change it.

Not sure exactly what could cause the broken plug. It looks like it got real hot. Was there anything unusual going on with the EGTs and CHTs ? Have you checked your GAMI spread to see if you have any rich or lean cylinders? As far as the severely fouled plug is concerned, those deposits came from somewhere. And that plug looks like it was running cold. Both of 6hose things could indicate a very rich mixture in that cylinder. How long had it been sense those plugs were cleaned? have you checked your timing? Read this: https://www.championaerospace.com/wp-content/uploads/2015/06/AV6-R-Aug20141.pdf

The plugs show almost no wear. The electrodes look brand new. The cracked insulator is usually caused by some severe trauma like overtemp or detonation. The severely fouled plug can only be caused my a very bad cylinder. It is not a plug problem, your engine is crying for help.

Sure, and I think those are valuable tests for a new product. But the reality is that it is legal to fly approaches with a 60 year old autopilot that barely works on a good day and not a modern piece of high tech equipment that works perfectly day in and day out.

I’m sorry you misunderstood me. I don’t violate the FARs I guess I object to the wording. It suggests that we need approval for everything we do and have to ask permission to get out of bed in the morning. I would have liked it better if they would have said that it was prohibited. I realize the two are synonymous in most thesauruses. That being said, aren’t we capable of evaluating if it works or not? Shouldn’t we fly all coupled approaches on a hair trigger to disconnect and hand fly the airplane to the runway? That’s the way I fly. i was flying Safety pilot with a guy once and during an approach I pulled the CB for the autopilot. He compleatly freaked out, got very mad, pulled off the hood and said if I ever screwed with his airplane again he would report me to the FAA (??). I said he needs to be able to hand fly the plane at any time. He said that he was not planning on hand flying today (??). To say the least I never flew with him again.

This is America, we are free to do what ever we want unless it is forbidden by law. We don't need approval for everything we do....

I think that information may already be in the ARINC messages the TruTrack is receiving. My Avidyne 550, which has a heading display, shows the position of the heading bug from the G5.

I didn’t see anything in the install manual that would exclude a plane with a G5 or Aspen. The TruTrack doesn’t need anything from them.

I just read the install manual and it only accepts ARINC and RS232 signals. I don’t know if the heading bug or error is transmitted through the ARINC messages from the GPS. I guess we will have to wait for an answer.

Except for burnt exhaust valves, cylinder wear problems usually progress very slowly. It usually ends when the oil consumption gets intolerable. I would give a borescope inspection more credence than the compression numbers. Now if the compression on one cylinder goes into the 30s or so, I would fix something. Other than catastrophic valve failure, cylinder problems are rarely a safety problem.
