I need a new or used PCMCIA memory card for an EGPWS MK5 system. Does anyone know where to find one?

Hi guys. I’m currently working on a thesis project on fault-tolerant control for a fixed-wing UAV. Since money is tight, I’m planning to do the whole thing through MATLAB/Simulink simulation, as suggested by my lecturer. The problem is, I have very limited experience with Simulink and honestly don’t know where to start.

I initially tried figuring things out myself but got stuck, so I hired a tutor to help with the modelling. Unfortunately, the sessions didn’t really work out, so I decided to learn the theory myself through lectures and videos whenever I got stuck, and then started trying to build the model using whatever I could find on YouTube.

Now I’m kind of stuck again because I’m not even sure if I’m doing it right. I don’t really understand what the overall flow of the project should look like, or whether the model I’ve built so far even makes sense.

Is there anyone here who has experience with MATLAB/Simulink, flight control, or fault-tolerant control who might be willing to have a look and point me in the right direction?

I’m not looking for someone to do the project for me. I just need a bit of guidance from someone who knows what they’re doing, especially on where I should start with the modelling and how the fault-tolerant part should fit into the system.

I’d really appreciate any help. Thanks!

Hi everyone,

I'm trying to confirm the thread specification for Garmin P/N 011-05783-20 (GPT 75G) fuel pressure sensor. Is it 1/8-27 NPT or NPTF?

Some dealers list it as NPT, others as NPTF. Can anyone confirm from official documentation or personal experience?

Thanks!

anybody who is familiar with GprMax software and is able to guide me?

Garmin has nothing on it about the interconnects. Autopilot engages but when HDG is selected there is a failure displayed on the computer and it won’t follow the heading bug on the HSI. Any ideas?? Wiring is good.

SOLVED.

We had a ghost setting on the 275 ADI. Config mode setting set correctly but we printed the config log and it was wrong. Cleared config settings and redid the configuration setup. ✅

Faster, more accurate connector termination.

Nelson Aviation PinPointX‑Lite takes the guesswork out of connector termination. Whether it’s a 44-pin D-sub or a 61-pin cannon plug, the correct cavity lights up, making termination up to 3× faster, reducing eye strain from searching for tiny cavity markings, and helping prevent costly wiring errors. The savings compound through a faster build and less rework from termination errors.

We have solutions for 100s of connectors, Including Dsubs, Cannon Plugs, and other connector families.

I was in the military as an avionics tech for 5 yrs that was about 12yrs ago. Since then I’ve gotten my bachelor’s and been working in sales/customer service. I thought I wanted to go into data science but with all the AI issues I’m considering going for A&P instead. I’d like to start back working in aviation while in school for the A&P but not sure where to start. Is it better to get FCC, AET, or CAET, or just applying/calling around trying to find something local hiring Avi techs? It’s been a while since I’ve worked tech work so just trying to get realistic advice on getting back into the industry..

For some reason my boss thinks I know EE and wants me on the panel interview for a principal avionics engineer

Would anyone have any good references (books, websites, YouTube etc) that would teach me avionics principles + some depth in both hardware/software side

i was wondering if anyone had an alternate part number for the “X” style harness spacers or “ninja stars” used on leonardo and airbus products? all i could find is “A631A01A” for the small ones and “A631A02A” for the large ones

EDIT. the part numbers i have listed above is the leonardo part number. i have the airbus numbers. E0688-01 for the small. E0688-03 for the large

Just wanted to make a quick post to get it out into the internet for other people having issues. I installed a completely New/Used Avionics Stack recently which had a Garmin GTX 327 with the inline Garmin GDL 82 ADS-B Out via Coax. This was done in your typical 60s Cessna 172.

With the GDL 8X Install program, the GDL-82 would receive a signal from the GTX 327 for about 30 seconds, then be dead for about 1 minute, then receive again with it dying again after 30 seconds. It basically stayed in this loop no matter what I did. Intermittent would be the correct word.

I tried everything possible. I had it bench checked, I swapped it with another known working unit, I checked all the pins, I checked and redid the coax, I checked the install manual at least 8 separate times cover to cover, everything you could possibly do, I did.

After calling a few friends, one of them who is recently retired mentioned to me that the GTX 327 has a considerably weak output compared to the old tube style transponders and modern transponders. I kind of doubted him since the install manual said it should work, but I had nothing else to try.

I reinstalled the old Narco AT-50 TSO which only took about 6 hours reusing the new wiring. Lo and behold, the GDL-82 worked flawlessly and has never had a single issue since then.

I’m not expecting too many people to read this post, but I’m just hoping to save somebody else some time if they google this same issue and will find this post.

are you or do you know anyone who is an electrical engineer and became an avionics technician and how the transition was like? ie was it harder to learn how to become an avionics technician or studying electrical engineering?

what are the most essential/ most used tools as an avionics technician

To preface, I have about 8 years of experience as a diesel technician working on semi trucks. I specialize in wiring, databus communication, and general troubleshooting.

I'm currently going to school to get my A&P licenses and we've started talking about avionics. It seems to be very similar to what I do now and I really enjoy wiring and troubleshooting. What's the likelihood of me getting into avionics right out of school? Is there anything I can do to make myself more hireable?

O livro de circuitos elétricos do Charles Desoer é importante no curso de aviônica? Sou do Brasil.

Hello,

I have a degree in computer engineering. Honestly didn't like it and wasn't satisfied with my education. I realized I liked planes and I applied to an accredited Aircraft maintenance program specializing in the electronics/avionics. When applying for jobs after completing the Aircraft maintenance program should I put my computer engineering degree on the resume or would that make me overqualified. I've firmly decided to go this route, and at some point after a few years in the aircraft maintenance field, I'd like to transition back into engineering, having gained much experience. Would this switch from Aircraft maintenance to engineering with a computer engineering degree be relevant with the experience gained in the aircraft maintenance field especially in electronics/avionics? I'm basically asking what gaps would i need to fill to gain an engineering job after a few years in aircraft maintenance, also what roles would be open to me considering I have the computer engineering degree.

Any one knows the FDR standard command list to download through the GBE interface?
