I would add this to the information presented in this video: In my 45 years of flying every checklist I have ever seen describes the procedure for doing a magneto check during the Before Takeoff checklist items. That is all well and good, and should always be performed. However, I subscribe to doing another magneto check after you land and are going through the Shut Down checklist. The reason for that is that it is possible to loose a magneto during the flight and you may not even notice it. If you check the magnetos just before shut down and find that one of the magnetos is inoperative that is the best time to report the failure to a mechanic so he can resolve the problem. That is much better than finding out you have a magneto issue just before getting ready to takeoff and then needing to delay, or even cancel, your departure.
I only worked in aviation a short time, back in 1970. After I got my A & P license, I worked in other parts of aviation, getting little experience. When you graduate from aviation school, They tell you to go out and learn to be a mechanic.I think a lot of people don’t know that there are 2 plugs per cylinder. I’ve learned more from watching these video’s than 2 years of aviation school. We never had a mixture control on the carburetor to kill the engine. I had little magneto training. They need to know that the magneto has a permanent magnet that produces spark in the primary and there is a set of points that shorts out the spark to ground, so the secondary doesn’t fire. I used to prop the 150’s and 172’s all the time until I took the starters to an automotive shop, replaced parts form an automotive starter had the same guts.
Basic concept and good for pilots. But there's plenty of magic in that component to discover how the charge is built up and discharged. Like you said its done by itself and its quite interesting.
If I may ask. What you mean. The only way to turn off the magneto is by grounding? I am thinking when you turn off on the switch you are connecting the positive to the any metal or metal casing 2nd) the ere just like you showed from magneto to the switch, no rallays or anything else? Thank you
The magneto has its own internal Timing that has to be set when the magneto is assembled. and then whe its installed on the engine it is timed to the engine.
There is a set of points in the magneto that opens the primary coil, then induces it into the secondary, at a high voltage, similar to how a transformer works. You can’t transform DC. It is constant, Ac alternates, reverses direction.
congratulations on your channel👍👏👏🎉🎉🎉.🎈you are the best, my name is Paul and I follow you from Bolivia I am a student of aeronautical maintenance and soon I will start my practices in ultralight, I do not know if you could make a video of the cessna 210 later, and something that I forgot, you could put subtitles in Spanish to all your videos, I apologize for my improvised English, thanks again and congratulations I'm your fan.
Thanks Paul!!! I really appreciate it!!! Thanks for watching and I hope the videos are helping! any Videos you would like to see me making on any specific topics?
Yep, Regular Tachs arent very accurate. Ive seen some that are off by 100 RPMS. The engine might be dropping 75 Rpms but only shows about 25 or 50 Rpm on the Tach. Really Im just looking for it to not drop too much, and also i dont like it when it doesnt drop hardly at all, like 25 RPMS or less. To me that indicates that a Magneto isnt timed Right.
very similar, but the only difference is a distributor has to have power form a car battery to create a spark, the magneto creates its own spark by using magnets.
I have a magneto plane.....it s written at the back in the oval Black bakelit (5,6..10)... cm..NILMOR...It s about 2 Kg.....my GD FATHER..used to say (it s s from the first WAR...1915.. )... you have to turn a manette to obtain a big spark..can you confirme here ON YOU TUBE..thank

That’s how it’s taught here in New Zealand, check before takeoff and before shutdown

The best explanation ever. I dont understand the FAA book. you got it.

Please keep making engine systems videos!! They are so helpful!!
Thanks a lot for your video!!! Please, keep doing this…
Thanks for vids like these! Im gonna take my practical exam next week and i needed some sources, good thing i found your vids on youtube!😃
Awesome! Im so glad they are helping you!!
Plenty of videos on these mags. How about the single drive mag on radial engines? A very thorough in-depth analysis would be great.
thank you for taking the time in making this video. Having these type of videos, help understand the books better.
You're very welcome!
Thank you thank you!!
I’m in Gainesville while watching this video
Thank you for the informative Video
Wow this was INCREDIBLY helpful. Thank you thank you!
My Pleasure Emily!
Thank u so much..
You are welcome!
so informative, the was you explain things is perfect for me !! thank you
great video. best explanation I've seen with impulse coupling to.
Just what I was looking for. Many thanks!
Glad I could help!
Thank you for the videos. It is great to see all the parts and understand how they work. Keep it up!
Thanks m8 u r extremely knowledgeable 👍
excellent presentation and explanation
Thanks!
more videos pleaseeeeeeeeeeeeeeeee- thank youuuuuuuuuuuuuuuuu
Thank you sir! 😎🙏
If I may ask.
What you mean. The only way to turn off the magneto is by grounding? I am thinking when you turn off on the switch you are connecting the positive to the any metal or metal casing
2nd) the ere just like you showed from magneto to the switch, no rallays or anything else?
Thank you
Great video thank you thank you
Glad you enjoyed it
Is the pulse timing built in?
The magneto has its own internal Timing that has to be set when the magneto is assembled. and then whe its installed on the engine it is timed to the engine.
What is inside the & what makes fire?
There is a set of points in the magneto that opens the primary coil, then induces it into the secondary, at a high voltage, similar to how a transformer works. You can’t transform DC. It is constant, Ac alternates, reverses direction.

So during engine run up, when checking the left and right mags, is a 25-50RPM drop in the normal range?
Yep, Regular Tachs arent very accurate. Ive seen some that are off by 100 RPMS. The engine might be dropping 75 Rpms but only shows about 25 or 50 Rpm on the Tach. Really Im just looking for it to not drop too much, and also i dont like it when it doesnt drop hardly at all, like 25 RPMS or less. To me that indicates that a Magneto isnt timed Right.
So does it act in the same way as distributors did in older cars?
very similar, but the only difference is a distributor has to have power form a car battery to create a spark, the magneto creates its own spark by using magnets.
Not all magnetos have or use impulse couplers. Lycoming engines only use impulse couplers on the left magneto.
Ironically, the Stearman he is sitting in front of doesn’t use impulse couplers either.
"Say 'OK' again one more time"...in my best Samuel Jackson imitation.
Seriously you supply great info but you must correct this public speaking issue.
So only 1 magneto is supplying spark during start-up until at least xxx rpm is achieved?
I have a magneto plane.....it s written at the back in the oval Black bakelit (5,6..10)... cm..NILMOR...It s about 2 Kg.....my GD FATHER..used to say (it s s from the first WAR...1915.. )... you have to turn a manette to obtain a big spark..can you confirme here ON YOU TUBE..thank
?
Say “ok” again…..
get to the point
