I’m pretty close to you right now. I’m at KJFX.

It is almost always the field wires. Check that first.

That kind of makes the AC worthless. Taxiing and climb is where you need it.

I’m not familiar with the Mooney air conditioning system. Where does the condenser get its air from? Where does it exhaust it too? Where is the evaporator air return? I’m thinking the condenser is sucking in exhaust and instead of blowing it overboard, it is getting into the tail cone. Then it is either getting into the cabin from the tail cone or there is an air leak in your evaporator circuit.

I have a 14v KX-165

You can. The KX-165 has an internal VOR decoder. If you want to use it, you have to add a couple of wires. If not, just plug in the 165.

Wow, I have an engine heater plug with the wires cut off too.

I tried to get a car near KLHW, but no dice. It looks like I’m still going to KSAV. And @Hank, our hotel is two blocks from the river.

Thanks for the info! I was going to go into SAV because of the rental cars. I will see what I can get at LHW. And I will read your article. I have never been there. The wife wanted to go. March would be more pleasant....

For effective breathing, we need to inhale through out noses and exhale through out mouths. That would require a CO2 sensor in your mouth. Perhaps it could be built into your headset microphone.

Getting the SpO2 doesn’t take any signal processing. Getting the respiration from it does.

The cable and mechanism are very difficult to get to. They are the type of thing that should be serviced every year. Most have never been serviced. If you remove one of your air vents, you can probably spray some lube on the mechanism and most of the cable.

Cool article you linked. It is a bit tricky to extract a ~16 breaths per minute signal from a ~70 beats per minute signal. Especially when you don’t actually know the frequency of either to start with.

They didn’t have a cannula on at the time. They didn’t put one on until they wheeled me into the procedure room. On further reading, it looks like you can get respiration from either the ECG or the Pleth. It also seems the pleth display isn’t well defined as to what exactly it is showing. I assume the engineers at the monitor company have access to all the internal data and have their own algorithms to derive the displayed data. Being an FDA certified patient monitor, it was compleatly validated.

I got a colonoscopy yesterday. They left be alone for 1/2 hour hooked to the patient monitor, so I started playing with the pulse ox. The monitor had ECG on the top trace, SpO2/pleth wave on the second trace and respiration rate on the bottom trace. It would take blood pressure about every 5 minutes. With what was connected to me I'm not sure how it was deriving the respiration, but it was. If I held my breath the trace would stop and it would start beeping. Anyway, back to the SpO2. I tried it on all my fingers with different orientations. It would always eventually get a good pleth wave and give a stable SpO2 reading, unless I didn't insert my finger deep enough into the sensor. It seemed to have an AGC function that would try to optimize the red and IR levels. I'm not sure what the pleth wave was actually showing. It could be the red channel, the IR channel, the sum of them, or the difference of the two. It could also be some derived combination of the two. Whatever it was doing, it was pretty robust and once I stopped messing with it, it would get a steady pleth wave and gave consistent readings. 98 in my case. If I jacked with it and the pleth wave trace went to hell, the reading always went down, never up, which is good. I couldn't get it to read high, but I was close to max as it was, and I didn't have CO poisoning either. https://en.wikipedia.org/wiki/Photoplethysmogram

will do, thanks for the offer.

I’m in no hurry. If I get stuck, I get to explore a new place.

I’ve never actually been taught any particular methods for going around, but I’ve always done it the same way. Power up till the yoke pressure gets a bit high. This will arrest the descent. Then trim nose down then full power. Gear up. Once you get 100 feet or so, flaps up. This whole partial flaps thing seems silly in a Mooney. A Cessna 310 is another story, it has real flaps. You can do all of this in about 10 seconds without rushing.

I’m heading your way on Saturday. Going to Savanna. The dry heat isn’t enough for me I need some humidity and mosquitoes. I will try to use the turbo.

The heat doesn’t bother me, but the bumps start at 11:00 and start tapering off at 4:00 and are mostly gone by 6:00. The tops of the bumps are about 11000.

Climb and maintain 70 degrees!

Perhaps, but those guys are already doing their things. In that case, it is the IAs that are pencil whipping annuals that should be punished. I have known a few.

I forget how many times we stopped, but the stops only took a few seconds to check what they read. We were checking the test box, altimeter, encoder and G5. He stops the test box, I tap the altimeter until it settles, then I tell him what the altimeter reads. He has the encoder on his test equipment.

I think the annual inspection should cure most bad maintenance. If the owner did bad maintenance, it would cost them more to correct it, so there would be a bit of negative feedback.
