Troublesome problem here. I have a 1986 Mooney 252, equipped with a KFC 150 autopilot with KAS 297B altitude preselect. There's also a roll-steering adaptor but I don't have the model number handy. For about a year once in a while (approx. once per flight) I'd get an excessive pitch up during...

No idea. Currently between mechanics as I've just moved.

Mooney Encore, 1986.

I just noticed this small dent in my wing near the pitot tube. Would anyone consider this necessary to repair for safety or reasons other than cosmetic? It's about 2" long and doesn't pierce the skin. Mooney Encore, 1986. Image link

I've been using a cannula for years in my Mooney and each time I tell myself to look into getting a mask for the higher altitudes and O2 savings. So finally I'm looking at the Aerox 4110-712 Series. I assume for the one without a built-in mic you put your boom mic in front of the black circle...

Thanks, makes sense!

I think my guy can get it capped, but is there danger running the engine if he can't (uncapped)?

Wow, really? Anyone know where I can find a diagram of how this works? Where does the other end of the hose actually connect? Right to the intake manifold?

Makes sense. Would this prevent the engine from running or just make the built-in manifold pressure gauge not work properly?

I just removed an Insight G3 engine monitor to send back for repair. Aside from the wire harnesses, I disconnected the manifold pressure sensor tube. My mechanic will be back from vacay in a couple weeks to reinstall and certify everything, but in the meantime I'm wondering can I start the...

Just showing --- (dashes) on the GPS display for any air related items. Indeed the static system is a likely source of the issue, as is the OAT probe (that's where Shadin initially suggested I look). But given the fact that the transponder altitude is affected (and corrects when the ADC is...

Not sure if I explained it correctly above. The way the Shadin guy explained it I THINK is that the gray code from the altimeter and the RS-232 from the ADC both come into the GTX 33 (maybe through the GNS 480, not sure) and it can fall back to the gray code if it's not getting the RS-232 data...

Ok, I spoke to Shadin to float the static heater idea by them. He said he'd never heard of that but suggested it's likely that both the ADC and the altimeter are wired to the transponder and that the transponder uses the altitude from the ADC unless it isn't receiving it and then uses the gray...

Thanks for pointing that out

Really interesting... I wonder if the temp control has broken and it's overheating, causing the static air to heat up as well. Seems possible. Disconnecting and capping the static line seems like the way to debug this. Only point against this is that the altitude problem seems to go away really...
