How Magneto Works | Simply explained for student pilots.

MAGNETOS have been around for over 100 years. Magnetos are engine driven electrical generators that produce high voltage to fire the spark plugs in an aircraft engine. Find out exactly how they work, in this video.

Lmao

[@twistedyogert]

That's the wrong kind of magneto.

[@domanigonzalez7139]

[@johnmcminn9455]

when was his first appearance?

[@Allan_aka_RocKITEman]

It's that anti-telepathy helmet. It REALLY gives him an edge...😉

[@Gearz-365]

Magnetos were also used in early car engines before the dynamo and alternator came to be. Very interesting stuff

[@NoosaHeads]

Best description of a magneto i have seen.

[@rondj1965]

This is a concise and easy to understand explanation video. Great job. Thanks.

[@michaelhazell9533]

Thank you, not just for this video but all the others you make. I've only recently discovered them, but i like that theres no waffle and straight to point but easy to understand. i wish you would make more

[@flightclubonline]

Thank you. More videos coming soon.

[@envitech02]

It's important to test each magnetos separately. Expect 50 rpm drop off engine if magnetos operated individually. After that do not forget to switch back to both. Check and verify. Sometimes the engine switch can return to single magneto operation due vibration or if knocked by the knee etc.

[@AdmiralofAlterra]

This was a well presented video.

[@GranVlog]

So simple and effective. The generator at our cabin is a very old Honda one, and it no longer works as the spark doesnt show when pulling the cord. Now i know why

[@IsraelConsonni]

this explanation is so simple and visually straightforward, it makes me want to cry

0:38 *enough VOLTAGE will generate a spark. Sparking is a function of voltage, such as when shuffling your feet on the carpet and touching a doorknob. Arcing is a function of current, as illustrated at 3:40

[@flightclubonline]

Great to hear!

[@samuelglover7685]

Very interesting and well done. I'm curious why aircraft use magnetos instead of an alternator/battery system, like cars have. Reliability? Better performance? Are aircraft spark plugs radically different from those you find in cars?

[@StephanAhonen]

Magneto ignition means the engine keeps turning even if the aircraft has a total electrical failure. Also, certifying anything new in aviation is an expensive process for a very small market, so piston engine technology lags well behind its automotive counterparts. Avweb has a pretty good video about the economics of the aviation engine market and how it has resulted in modern planes with space age composites and sophisticated avionics still using engines essentially identical to aircraft from the 60s

[@FlyingCoon]

Thank you for another great and simple video! As you described at the end there are two magnetos - why is the performance better with two magnetos and why does the power drop slightly when I test the individual magnetos?

[@alianjohnson6035]

as the video stated there are 2 mags and as such there are 2 spark plugs per cylinder unlike a car where there is only one plug. having 2 spark plugs spaced within the head of the cylinder allows the air fuel mixture to be ignited more evenly/uniformly and therefore more efficiently ie more fuel is burnt in the cylinder with less waste and as more fuel is burnt you get a bigger bang and more power. the power drops when individual mags are tested because initially you are running on 2 spark plugs then testing you are basically earthing one mag which effectively stops that mag working so when you do the test you are running only on one mag and one spark plug and less power.

[@thunkjunk]

@@alianjohnson6035 What would be the thinking behind using one vs two on a flight?

[@user-hd2xm4jz1u]

thank you very much the explanation was very clear

[@flightclubonline]

You are welcome!

[@loags73]

Tidy explanation. Keep the videos coming!

[@flightclubonline]

Thanks, will do!

[@Swaggerlot]

This raises a point that as an educator I have raised many times. For example, one of the industries I developed training in was heavy locomotives. The training was full of totally useless content about how the systems worked. Useless because it did nothing to train them to identify and resolve any issue that arose (if they could at all). I'll add that much of my life was involved in aviation.

[@NickWeissMusic]

I love that model T technology is still relevant

[@BruceDuncan]

Nice! Can you do capacitive discharge ignition next?

[@coffee3513]

Thank you for the understandable video. It is so great.

[@AudioNaut93]

It’s the thing that keeps your spark plugs firing therefore keeping your engine on which is a lot better than it being off. That’s all pilots need to know.

[@waynenocton]

This is either really good, or wrong, and I’m leaning towards really good. I’ve always been taught the reason for the capacitor or condenser is to stop the arc as mentioned but for the purpose of preventing damage and wear to the breaker points. But what this video stated makes good sense.

[@alexcurmi7412]

I’m pretty sure it’s the same reason. The arcing can cause the conductor to degrade because it generates a lot of heat because air has a high resistance. Maybe that’s what it’s referring to?

[@zarrokea]

Thanks these videos are so simple and well made !

[@flightclubonline]

You're very welcome!

[@qatarairwaysflybywirea320]

Please do some videos about aircraft electrical systems( generator,alternator etc.....) I'm waiting to watch, quick actions would be highly appreciated I have ATPL exmas so please do it as soon as possible

[@tobyodonnell9353]

Start reading your books

[@TheReadBaron91]

If it’s a small aircraft, pretty much the same, if even simpler than a typical car.

[@adamdelarozza1985]

Don't forget that a Magneto doesn't Need electricity (unlike a Generator) from a Battery and will work on it's own! A redundant magneto system is wise 25,000 feet in the air😃

[@ArneChristianRosenfeldt]

You can connect a generator directly. No need for a battery. For example you could use the AC ( like on a bike ) and distribute every lobe to a different cylinder and there have a coil on plugs for a shorter HV cable.

[@Tg-gz8qt]

Both magneto and generator (alternator) are engine driven and they are the one that produces electricity. I don’t understand what you mean by “unlike a generator that needs a battery” ? Cuz a generator doesn’t need a battery, its engine driven

[@dennisjohnson8753]

Good explanation

@@flightclubonlineThank you very much for the recommendation

[@firass465]

You should know also that Magneto Discovered by Robert Bosch 1861 - 1942.

[@onetruekeeper]

Does the battery power a starter to turn the magneto which powers the spark plugs ? If not what turns the magneto to begin with ?

[@karhukivi]

The battery is used to start the engine at the same time, all turn together.

[@233kosta]

Why are the gears plastic?

[@tbas8741]

Interesting side note: That high voltage needed for spark ignition in modern engines is in excess of 20,000 volts With car engines and their coils making upto 68,000 volts for high compression or high boost engines. Even on a motorbike you are looking at 15-20,000 volts from a 6v motorbike battery.

[@ArneChristianRosenfeldt]

When the spark happens in a region of calm air, the flame expands slowly. So we can advance the timing before max compression at TDC as the turbo spins up.

Mag = large. Neato = cool. And with the vernacular stepped back a generation or so... THE BIG NIFTY!

[@carmenchacon726]

but it does not say what happens when applied to my knees.

[@maxheadroom1506]

why not use alternator like in a car?

[@StefanoBorini]

I am willing to guess weight and complexity. Also it needs to work in any conditions of weather, altitude, temperature and atmospheric pressure. I am willing to bet these requirements are not satisfied by an alternator, although I can't say how.

[@jhbf]

to be completley honest i still dont get it, especially with the voltage spike, but great video nonetheless

[@StefanoBorini]

When you have the closed circuit, there's a lot of energy accumulated in the magnetic field of the coil that is created by the current flowing. When you open the circuit, that energy has to go somewhere. With nowhere to go in the first circuit, it can only discharge through the other coil (since the first one is now an open circuit). Energy can be delivered either through current or voltage. By the way it's designed, the other coil favours to discharge the energy through voltage. This results in a spike which reaches differences in potential enough to make the air in the combustion chamber break down and let current flow through the massive voltage. Imagine a massive pump delivering a massive pressure spike through a narrow pipe. The pipe blows up. That's the spark. It's like a water hammer, but for electricity.

[@pauldmann1166]

I’m surprised distributors are still used and not electronic ignition.

[@StefanoBorini]

electronics tends not to deal well with extreme temperatures, and you get those a lot in an airplane.

[@ArneChristianRosenfeldt]

@@StefanoBorinimil spec electronic survives where humans die. Military jets also hvac their computers. Use tubes?

[@kenmohler4081]

Did I miss the purpose of the magnet?

[@ArneChristianRosenfeldt]

Dynamo . Yeah, I want EFI and lambda probe. I need electric first. Hand starting a propeller leads to injury

[@Notabot101]

This explais how he beats wolverine so easily

[@itsjohannawren]

The terms in this are mixed and contradictory. Please, don't pay attention to the actual terms. "High-voltage electrical current" is not a thing. Current is measured in amps. Voltage is its own measurement.

[@flightclubonline]

Fair point. Thank you for clarifying.

[@karhukivi]

Thee is a distinction between a current driven by a Van de Graff generator and a current driven by a car battery. If you want to drive a current through a high-resistance path like air, then you need a high voltage. In this video there is no need to measure the current, so no mention of amps.

[@Alexandre-zv8gd]

I'm taking the commercial checkride and failed the oral because the examiner I guess wants me to be an A&P. I guess I need to know how to overhaul an engine too. Does anybody know a DPE that isn't on a Nazi power trip? They know how badly you want to pass. You hand them $800 and they say you failed. Come back and pay me another $800. Next customer. Bunch of Cartels is what they are.

[@Lembobwaii]

Are you trying to get your A&P ?

[@4-7th_CAV]

My suggestion: Talk with some other applicants, and their instructors, to see if this is a common occurrence. If it is, then contact your FSDO and report his actions. I realize that there is also his side of the story, but if he is not conducting practical exams in accordance with the appropriate ACS (or PTS if applicable) I am sure the FSDO would like to know that information.
