Updating Panel with New Switches and Annunciator Lights
gevertex replied to Me & 8883's topic in Avionics/Panel Discussion
I can post my logbook entry once I get the mine back. It's supposed to wrap up this week. It was supposed to wrap up 3 weeks ago... but who's counting. They seem slammed so I give them a little slack. -
The replacement switches are apparently breaker toggles and have a circuit breaker built in. I didn’t know that was a thing until recently. Kind of cool.
-
Thanks guys. I though someone was yanking my chain at first.
-
I hope you are joking. Where? I can still correct it.
-
Final panel design. Being cut now. I was able to get the shop to replace many of the switches with circuit breaker switches. They did not want to replace the field alternator or master switches. Added 2x LEMO plugs on the panel and moved GA headset plugs to panel. N9127S Pilot Draft 7.pdf

Looks great. Fixed that for those of us that can't see upside down.
-
Nice. We have basically the same airplane.
-
I’ll ask again about the annunciator. They might be too far along at this point. I am also at budget for this project. I am hesitant to spend more at this stage. It probably wouldn’t be too expensive though. I like the idea.
-
I need to redo the interior at some point. I’ll address the insulation then. I had no idea there was fiberglass elsewhere in the airplane. I’ll check it out
-
Progress picture.

I agree. This is unfortunately a problem for another day. I am at budget for this project and it’s almost complete at this stage. I have 3 or 4 light’s remaining that are useful.
-
I’d like these also. I have a panel being made now. Could also make some nice embroidered hats too.

Latest panel draft.

It’s pretty handy for sure. You just have to be careful with cheaper devices as more than a few of them use the USB-C port but don’t implement the USB 3.2 spec meaning they are just dumb 5v power supplies. There is also USB4 which is also used on the USB-C connector. USB4 can apparently go up to 48v and 40Gbps of transfer rate! https://en.m.wikipedia.org/wiki/USB4
-
If it's true USB-C (implements USB 3.2 spec) it supports 5-20v. Up to 20v can be negotiated with the USB-C power supply. That lighter plug adapter will have an embedded chip that negotiates 12v power. There are several manufacturers now that make USB-C cables (each cable negotiates the rated voltage for the device) that serve as power supply replacements for those devices. Using those cables you can use an array of USB-C ports instead of separate power supplies to power your devices.

Draft panel arrangement. As some have suggested the GNX 375 may need to go below the GDU-470. Any thoughts on the autopilot panel placement? N9127S Pilot Draft 4.pdf
-
That would be quite the chain of cables, but you'd be able to use a 12v lighter plug devices with it.
-
Yes, it’s 24v. I plan to have both USB-C and 24v outlet for flexibility.
-
Too late for that. Most of the installation is already done. I'll keep searching.
-
Is there a regulatory rationale you can cite? I am being told by the avionics shop (got a call just now) that they have to be PMA and I don't see any switches that have a PMA part number on aircraft spruce. But... Maybe I am missing something? I see plenty of certified aircraft with lever or push-pull switches.
-
Closing in on getting this finished. Question for the group. I am looking at putting new switches in since the rockers are hard to come by / expensive. Do they need to be TSO or will anything work? Any recommendations / links? For instance, I have seen others with toggle switches in place of the rockers. Thanks!
-
Good point.
-
Interesting idea. I wonder if they could go where the suction gauge is now.

I believe this is showing a backup communication bus not a backup GSU 25. Normally GSU 25 communicates via arnic or canbus afaik. This shows backup RS-232 connection. Does the diagram show a second GSU 25 block?
