ARINC 825 devices

Hello fellows.

I'm researching ARINC 825 devices, and the only things I find are ARINC 825 controllers, data loggers, and interface devices. I'm finding it hard to encounter sensors, actuators, motors, or other devices.

Do you guys know any products that have an ARINC 825 interface?

Tool recommendations?

I’m currently a student who is planning to go into avionics. Are there any basic/essential tools y’all would recommend while I still have access to the snap on student discount?

Thoughts on these?

Looking to possibly buy some. Are they any good? Is the 30° offset any better? Cheaper alternatives with “robo grip?”

Bad financial decisions part 2 electric boogaloo

So about a month ago I made a thread asking for advice on getting my Cessna 140 instrument rated, despite the stupidity of this decision financially, I went ahead and put $15,000 into a $30,000 and got a gps, nav radio, audiopanel, and dual Garmin g5's. Last thing on my wishlist is an autopilot however I cannot seem to find any approved for the Cessna 140, Google says the KAP140 is however I cannot find any actual evidence that it is. Does anyone know of any approved autopilots or stc's available for autopilots on the 140

Advice on Career Opportunities in the Aviation Sector with Visual Impairment

need your opinions and advice regarding my career. I am a first-year student in the Aircraft Airframe and Engine Maintenance program in Turkey, and unfortunately, I lost vision in one of my eyes due to an accident. My passion for the aviation industry has been with me since childhood, and I am eager to progress in this field. However, I am wondering if I will face limitations regarding job opportunities.

As a technician with a visual impairment, what path should I follow to work actively in the sector? Are there any resources or groups where I can connect with individuals who have similar experiences or have gone through this situation? Additionally, I am considering an academic career in this field. I would appreciate your advice on the chances of being accepted and succeeding in the sector as a technician with a visual impairment.

Thank you,

VIR20 Madness - 501 Citation

Pop quiz, hotshot:

Nav2 performs flawlessly. Nav1 is on an MD41 switch with the GPS. Nav1 audio is clear, but very quiet. Nav1 will not pull flags or move the CDI on any frequency, VOR or ILS, on a ramp tester or the local VOR. Swapping radios changes nothing. Antenna connection verified, both radios see the Nav antenna just fine, thanks. OBS info to the GNS is unstable. Wanders around the value of the OBS ± 3° and drops out for ~.5s at a time every second (or so).

I'm at my wit's end.

About to swap out the MD41 relay box but the NAV audio doesn't go through that so I'm dubious that it's gonna be the sum total solution.

Ideas?

Requirements for a rockets flight computer?

Hi reddit I have been placed in charge of developing a custom flight computer for my schools rocket. Currently the target distance is 180km which comes with new challenges.

I was hoping I’d post this on here to brain storm some requirements. Current what I’ve thought of is: -Dual channel deployment for main and drogue parachutes -3 axis gyroscope -Special connection to our custom accelerometer -Short range 2 way communication to start initial launch -Connection to long range 1 way communication to send data -Altimeter

Is there anything I could have possibly missed in my assessment? Any help is appreciated thank you.

Snr uk electronics engineer seeking to move into CAA regulated avionics install, repair, test etc.

Hi, I've worked in design and test of scientific instrumentation for much of my life, and have an opportunity to branch into avionics to do similar, ie. repairs, modifications, upgrades, safety & functional assurance, etc.

I'm aiming to cram all the part 66 exams ASAP, and there seem to be 14 units to it altogether, eg.

https://training.resourcegroup.co.uk/product/part66-selfstudy-b2bundle/ and scroll down a bit :)

Question: how much of my background might let me skip any of the most elementary modules, or have you got to do the lot for accreditation?

Anyone else jumped through these hoops lately?

Kind regards!

Where do you source parts like slip rings, switches, and small electric motors?

I'm working on designing an instrument, and to keep things easy I'd really like to find off the shelf parts. Business is business and every dollar spent on custom solutions is just more bullshit to deal with.

Is there a good general source for this kind of stuff, or is it all handled by small companies each doing their own thing? It would be even better if I could get non-certified parts for prototyping with references for certified parts when the final evaluation prototype is made, and subsequent production models.

Horizon P-1000

Does anyone know how to set a new tach time on a used Horizon P-1000? The install manual says you could send it back to Horizon, but with them being out of business I'm having a hard time finding out if it's even possible to do on my own.

Can AE become avionics engineer?

I’m first year AE student and I’m really interested in programming and electronics. I know C/C++, python, basics of electronics and I’m starting with Arduino. Should I switch to EE/Embedded systems or maybe it’s good to stay and go on with AE. My course doesn’t have specialisations related to avionics.

How to get into avionics in Missouri

I live about an hour from St Louis, I'm really interested in this field but have no prior experience. I'm considering going to Missouri State technical college for the aviation degree, but I really don't know where else to start. Is this a good school to get my a and p? If anyone has any suggestions or any input I truly appreciate it! Thank you in advance! Just any information in general would help because I know very little about it all, but I love airplanes and working with my hands on electronics.

GI275 GMU44B CALIBRATION FAIL

Hello everyone,

I have just completed the installation of a GI275 with GMU44B, and I have a problem during the magnetometer calibration. Every time at the end of the calibration procedure "Calibration Failed" message appears.

On the diagnostics page it seems that there is no data transferred through RS232 between GI275 and GMU(black square). The RS485 works properly.

I have already checked a second serviceable GMU.

Does anyone have in mind what is the root of this problem??

Thank you in advance.

Problems in Avionics

Hello!

My name is Christian and I am a student from The Netherlands. Currently I am researching the field of avionics for Standard GA and home-built aircraft, with the goal to find as many inconveniences or problems within this field.

With almost every product there is something wrong, sometimes we know exactly what, and other times we don’t realise it immediately. That is why I am trying to find out what people involved with GA aircraft think is wrong with avionics. With the goal to find problems that a lot of pilots, maintenence crews or plane owners can find themselves in.

This question can be complex and sometimes it requires to think out of the box, or maybe you already know exactly what find annoying.

So this is my question to all the people involved with aircraft:

What inconveniences or problems do you experience in regards to avionics?

I’m very curious what everyone comes up with, Thank you!

Sanity Check

I just did a thing.

I purchased a Piper Arrow. It has:

GMA 340 KX 155 with Glideslope KX 155 KMD 150 KLN 94 L3 Lynx Piper Autocontrol 3

Initially, I wanted to replace the KLN-94 with a GNX-175 and then install a pair of GI-275s that could interface with the AP and remove the vacuum system.

Then I had the avionics inspected, and it was determined that the KX-155s needed to be overhauled, and the autopilot was barely working with some Mickey Mouse wiring /soldering.

I decided to keep one of the KX-155s for Com 2, change from a GNX-175 to a GTN-650XI, and put in a GFC-500 A/P

Now the shop is making me a seemingly sweet deal on a G3X Touch for an extra $3,000 vs the GI-275s. Seems worth it.

What I’m not doing:

New custom panel EIS New Nav/Com 2 New Transponder that will integrate with the Garmin gear

Am I crazy?

Edm 900 high oil psi, never changing.

We did a 100hr on a cessna 172G w/ continental O-300. During 100hr it received an EDM suite. It's constantly reading 125psi on the oil, never changing.

The transducer is good. The plug to the transducer is good. Where else should I check? Boss wants the bird out tomorrow to fly down to wiley post for paint, this is the only hold up.

UPDATE: situation was resolved. A non-electrical type with delusions of grandeur pinned the plug wrong and very poorly. Thanks to all for the suggestions.
