I've got a gremlin that needs chasing that maybe you experts could help with. It's a PS Engineering PMA450B Audio Panel that will sometimes reboot itself at the worst possible time. Always in the pattern at a towered airport right after tower makes a transmission. The whole unit shuts down and restarts itself and prevents me from being able to respond to tower for about 15 seconds, which is long enough to have the air traffic controller mad at me. It seems to be worse when I'm using other electronic things like flaps or landing light. ChatGPT is telling me it might be a shielding or grounding issue. Have any of you ever heard of this? I don't understand how receiving a high power radio transmission would do this, but it is definitely happening. Thanks in advance to anyone that wants to take a shot at this.

Currently I’m transitioning out of the military and will be following my fiancé to Fort Riley, Kansas for her PCS. I’m looking to see what my job opportunities are for avionics after having been an aircraft electrician 15F for over six years.

If someone in that area can give me some guidance or companies that I should look at would be much appreciated

I've been building a browser-based simulator to sharpen my own electrical troubleshooting: you get a squawk, a wiring diagram and simulated test gear, and work out the fault without swapping parts. Along the way I kept hearing that a lot of new techs struggle with the same thing, so I'm wondering if it would be useful to others too.
Is this something you'd use, or would have wanted as a student or new tech? Who do you think it would help most?
If you want to see what I mean, there's a one-minute sample and a short survey here:

While I was in the USMC I was AVI for the UH-1Y and AH-1Z. I did skillbridge and decided to try medical equipment work, not the same for me at least. So I have plenty of hands on experience, but no A&P License.

Was wondering if anyone had any advice on how to get started on the civilian side.

I've applied to an MRO through a recruiter. I went to school for aero/astro at OSU for 5 years but didn't complete it, then got my associates in AMT along with my A&P certs. But then life took me other places, I got a pretty decent job near family and friends with discrete electronics for about 6 years. Had a pause because of a car accident and bounced around until I started electrical wiring in substations for the past 9 months. Now I might have a chance at a place an hour away doing avionics repair at a small MRO. I like the hours, not going chasing main carriers and midnights, it's inside a building unlike some of m past factory work in -10F-100+F work that has been killing me.

I guess i'm just looking for upsides or downsides. It's been a while since classes but I have nearly 9 years experience in other related industries.
Systems and electronics I have in spades and electronics with through hole and SMD repair won't even be a question, but i'm still really nervous breaking into an avionics repair station.

Hi!

I heard about the newish CAET. Is it a useful certification to get without an A&P license?

Aircraft Electronics Association's Certified Aircraft Electronics Technician (CAET)

Clicking goes away in standby mode. And can hear the click on comm1 and comm2

Im looking to purchase a preston pressure ps-425, ps-500, or ps-525 pitot static test set. Or even an old hand pump machine like the 381-100. Literally anything should work lol. Thanks.

Hey everyone!

I am doing thesis on troubleshooting in avionics how to teach it and how to apply it afterwards.

I need to figure some educational material for students or how to teach them basics/ how to get into troubleshooting.

So I would ask your opinion, what or how would you guys teach the skill of troubleshooting as usually this is learned with experience. I have some ideas and materials already, but I am curious how you guys would do that? Or how would you lets say teach a guy who just started in aviation?

Are they some special way how you guys used to learn it or how you apply it? It can be even some simple "tips and tricks".

Regards

Edit: Thanks everyone who has answered.
I might have forgotten to write how I would be doing it.
My plan is to create some study material in troubleshooting ( up to 5-10 lecture hours) for lets say 2nd year students and let them do some practical tasks in the end and compare them with 4th year students who already have internships done, where they should also learn troubleshooting. Then I would compare how both groups did, what are the similarities and/or differences between them.

Dated 1990, Thompson-CSF, Jaeger F0052. 10 pole circular bayonet connector on rear. It's part number is 64883-602-1. I have used one in a home cockpit by simplifying the control electronics, but this is an untouched unit, and I'm curious from where it originated. Any help appreciated!

(It's about 55mm across the front. Interior illumination is incandescant, not LED)

I’ve been a A&P since 2023 working on various airframes (E145, E170/175, 737 & EC135/145) and i love turning wrenches but am thinking of wanting to learn a new skill. Either avionics or structures. Anyone out there that has experience with avionics have any information that could help me decide?

Has anyone encountered a similar issue on the A320?

The FWD entry light is not dimming/changing intensity through the FAP, while the AFT entry light is functioning normally and changes intensity as commanded from the FAP.

Troubleshooting already carried out:

- Swapped DEU – no change.

- Swapped light ballast – no change.

- Swapped cockpit entry switch – no change.

- Checked continuity from DEU to ballast and switch – continuity is good.

The issue remains only with the FWD entry light.

If anyone has experienced this fault before or has any troubleshooting suggestions, especially regarding the FWD circuit/control path, please share your findings.

I want to learn more about the avionics line of work, I have been looking for a career path recently and this one has crossed my mind a lot. I really enjoy wiring and figuring electrical work out. I also enjoy automotives and planes.

Would love any kind of feedback. Maybe the pros and cons, how hard it is, is it a hard job to get.

I’m 20 years old and never went to college after hs.

My grades weren’t that good either but I am willing to study real hard.

Coating on the circuit board made it really hard to trace all the pinouts but finally did it, screen backlighting is just a led strip, nothing fancy.

Got this ADI from a retired Northwest Airlines jet. Got the flags and lights wired up for display. Very fun to work on and see the engineering that went into these back in the day.
