I blame the modern technology. When we were young, when a plane flew over, we ran outside to see. It seemed magical, and we longed to be able to "do that". Now, any kid can buy a video game that seems much more thrilling than the real thing. For $20 and no effort or risk.

Annual turned into engine overhaul. Jewell Aviation
DonMuncy replied to MATTS875's topic in Modern Mooney Discussion
Only in aviation would "only" and "$7000" appear in the same sentence. -
#3 Cylinder runs very hot after overhaul
DonMuncy replied to Greg Ellis's topic in Vintage Mooneys (pre-J models)
First thing I would do is swap the 1 and 3 CHT probes and fly it to see if perhaps the # 1 might now show the high temp. Thus a bad probe. I had it happen on my K model. -
Absolutely amazing. I wonder how often one of those robots go out of adjustment, and have to be tweaked.
-
It is not hard to do a capacity check on the battery (OK, you do have to have the equipment). If it checks out good, no worries. If not, replace it.
-
I think the thought process is that one often needs a light to unload the plane after a flight. Not a bad thought, but it has cost many batteries. The shut-down timer is an easy fix.
-
Bear in mind that (at least in the modern planes), there are two senders, one at the inboard end and one outer end.

With the cost of the timer and ease of installation, I consider this one of the "best bang for the buck" things you can do. I know that many people fly a lifetime without having the problem, but one battery is one two many.

It is not too much more than that. But some. Getting (or designing) a timer good for 30 seconds or so is easy. Getting one to stay on for 10 or 12 minutes is more of a challenge. Basically, the power feeds into a capacitator, and when the power is removed, it then bleeds back through a resistor. Sizing the capacitor, resistors, diodes and the transistors to get the timing right is the problem. Thus the Darlington pair transistor set-up. And yes, it requires a relay to carry the power for the lamps.

Good luck

After I ruined my battery leaving the cabin light on, I designed a circuit to keep the lights on for 10 or 12 minutes after the master switch is turned off. It is an electronic circuit with a darlington pair transistor set up. I have a couple of them made up. Naturally, they are not STCed, so would need to be installed as a minor modification by and A&P, or a reasonably talented hangar elf. Let me know if you want one, or I will be glad to give you the diagram so you could build your own.

The only one I am aware of is the one I make.

Are you happy with the result? Do they fit flush with the cowl like the originals did? Is there any downside, other than cost?
-
Thanks guys

My granddaughter is interested in a career in aviation. Is anyone knowledgeable about scholarships available for females in aviation.

I'm glad I have people smarter than me to explain this stuff to me.

I thought the cited "new ยง 61.57(d)" read differently. Maybe I'm just wrong.

No, at one time, if you didn't meet the currency requirements, you could fly with an instructor and do the 6 approaches etc. within the next 6 months OR do an IPC. Not much of a change, but still a change

As everyone here knows, I am a charter member of the CBs. But when it came to my glare-shield, I sent it to Hector. It is really nice.

Thanks everyone.

I went out to the hangar this morning. After cycling the autopilot circuit breaker, everything seems to work fine. We may never know! Thanks for all the help. If the gremlin returns we may have to revisit it.
