ASP - Magneto Ignition Systems

This video is an overview of Magnetos and Ignition Systems for the AVS-167 course.
I made this video as part of a class in the Portland Community College's Aviation Science professional pilot program. It's a two-year program that helps people start their pilot careers. If you're interested, you can visit our website at www.pcc.edu/fly

Thanks. This is much better than handbooks from the 1970s that they gave us in class. Lol “it’s a mechanic thing”. That’s adorable. A&P’s ✌️

[@B59h]

Extremely well explained. Thank you. I honestly have not heard or seen it explained better anywhere else

[@j.chenmuas]

This explanation is more clearer than how my instructor word it to me last night, thanks you!

[@pccaviationscience6769]

Glad it was helpful!

[@FlyingWildAZ]

Larry you are amazing. You have a gift to explain clearly and efficiently.

[@pccaviationscience6769]

Thanks! Glad it was helpful.

[@jhansen55j]

Excellent explanation. Came across this video while troubleshooting the Wico-X magneto in my 1936 John Deere Model A. It not only educated me on the tractor application but more importantly, for the mag installed in my ‘77 C172. Thank you very much.

[@pccaviationscience6769]

You’re welcome! Glad it helped.

Currently taking Ignition and Starting Systems in A&P school. I was in class today and it just wasn't clicking. Thank you for posting this, I get it now.

[@jeffreyfalls8951]

Thank you thank you thank you. I just bought a case trencher with a v4 with a magneto and I’ve never touched one before and now I see everything I was doing wrong

'just a GA pilot trying to understand better how his airplane works. Excellent job!! 😎 Thanks!

Glad you liked it! Thanks!

Im repairing an old tvs-90 lownmower....this video really helped me...

[@eduardocardenas1165]

Thank you so much currently working on my power plant FAA written test was really struggling with electrical/magneto Systems your video really help me understand and picture the questions in detail.

[@pccaviationscience6769]

Glad it helped! Good luck on your written. Those tests are really challenging.

[@Casry12345]

working towards my AME license and these videos are bang on. Super super helpful. If you aren’t already a teacher, you should be.

[@pccaviationscience6769]

Thank you! And I am. These videos are for the classes I teach for Portland Community College in the Aviation Science program. I'm glad some people are finding them useful!

Hi Larry - Thanks for sharing this excellent video on magneto operation. - Jim

Very well presented keep up the good work.

Gracias.

[@pccaviationscience6769]

Haha! Sweeet! All I need is a couple million people who are REALLY interested in magnetos. Hope things are going good for you, Brian!

[@June-lf5hx]

Hi, that's a great video. Thank you! And you mentioned on the video that some pictures are from the textbook. Could you please tell me what is the name of the book?

[@Gl4uc0n]

The book is FAA-H-8083-32A. The AC 65-12A has the same pictures in black and white and can be found the FAA's website as a PDF.

[@June-lf5hx]

@@Gl4uc0n Thank you so much for your information!

[@pccaviationscience6769]

Sorry I didn't see this sooner. We use the AMT handbooks, which you can get for free from the FAA website.

[@2polev355]

Dude is grinding up the spelling typos in the 8083. 😂 glad to see that everyone hate that damn book just as much as I do.

[@mademoisellepunk777]

Ummm where is the d2l link to the virual mageto ? And thanky you for the vido ofc :)

[@championassetmanagement4889]

He mentions the link at minute marker 8:08, but didn't see it either. Where is it?

[@MeiGunner]

if the coil have more Turns ,, does that Give it more volts?

[@pccaviationscience6769]

Yes, though to be precise it is the RATIO of the number of turns in the primary to the number of turns in the secondary (along with the strength of the magnet and how fast it is turning) that determines the final voltage. That ratio works the same way in transformers, too.

[@x-techgaming]

11:17 Centrifugal dogs? Haha. Flyweights?

[@pccaviationscience6769]

I'm guilty as charged of using slang there. However, "dogs" usually refer to something that engages to stop movement, and these are centrifugally (centripetally?) activated, so... I'll stand by my centrifugal dogs. Ruff.

[@jhunyorgarcia2558]

how to test a motorcycle magneto

[@pccaviationscience6769]

Sadly, I'm not up to speed on motorcycles, though I worked on one a bit as a kid. It was very different, at least in how it was built, but the principle is probably similar.

[@devilswish8876]

the original magneto does not need those things and it was a dc magneto ac is not necesary at all

[@hubercats]

I think this is a matter of semantics. To cause a spark, the current through the primary has to change with time. The faster it changes the larger the induced voltage, hence spark. So the current does indeed change with time (I.e., it “alters” with time).
