- In this video, we show the components of the electrical system on board the Cessna 172S. Here you will learn how electricity is generated and distributed throughout the airplane.

Whoever made the animations for this video is an artist and loves his work. They should be very proud that their work is still helping people 6 years later here in 2023. I'm starting a&p next month! getting ahead of the curve with these vids!
"not the bus that brings you to school, BUT AN ELECTRICAL BUS!!!"
Yeah that moment was weird :) But this video by and large is very helpful in my opinion
I really needed that clarification.
It's a dad joke/wordplay :)
This will need further clarification someday when electric school buses become standard :)
Both can be short In some way.
Great videos! You really put a lot of time into them and production value pays off
This is extremely helpful, I love how clear it is!!
This channel is absolutely amazing. Everything is explained so well and made very simple to understand. It complements my studies for my PPL written exam very well. Thank you so so so much!!
Nice overview of the electrical system.
One fault I see. 1:25 - Circuit breakers trip when Amps or Current exceed the breakers rating, not voltage.
Also, circuit breakers utilize magnetism to function, not heat. Fuses on the other hand do use the heat produced by current to function. Anyway, awesome video series, thanks @ERAUSpecialVFR for sharing your work.
Thermo-Magnetic Circuit breakers, as you can tell by the name actually use both depending on the amount of excess current. The thermal part part of the breaker is activated during current overloads. An overload is anything more than the rating but less than the super high currents associated with a short circuit. Klixon breakers' data sheets for example shows that at 200% rated current, the breaker will take from 2-35 seconds to trip. The ambient heat will affect how soon it reacts on overloads as well. The other (magnetic activated) half of the breaker reacts to short circuits. The short circuit current will be in the range of 1000% or more of the rated current. That will be enough to pull apart the contacts and open the circuit within half a second.
While there are magnetic only breakers that protect motors from short circuits, they rely on the overload heater in the motor starter for overloads. For most other applications, the thermo-magnetic breaker is what is used as a fuse alternative.
Great summary. Thanks for this.
This channel explains everything so well! Thank you!
This channel explains soo well...thank
Hoping for more such videos
This series is amazing, so much info so clearly described and as a bonus some of the best dad jokes around, 1:51. The nr.1 one is in the static instruments vid @ 4 min 17 :-)
First of all i sincerely want to thank you and share my appreciation about the whole videos which explain the Cessna 172 systems and parts very well, on the other hand ,for this video individually, the duration of the video and the content are not satisfying.
Awesome video with great graphics! Thank you for sharing this video. I subscribed your channel!
Normal people can understand working of electrical circut in aircraft through this video.
Great video 🙌 so well said and easy to understand
This is what I needed. Thanks alot for the video sir😍
Lol “not the bus that brings you to school” had me weak!
This series is amazing, so much info so clearly.
Excellent video amazing visuals very informational
Thanks for the video, man
thanx brothers from morocco ....
Love it!
Thank you it worked!
« Not the bus that brings you to school » excellent 😂🚌
Really Great 👍👍👍👍👍
Sir please please please try to upload the electrical or different systems of jet engine , narrow body or wide bodied aircrafts, That will be very helpful. This video helped a lot thank you
had to save this masterpiece !
thanks for your video
I like the power strip analogy.
I like it so much
Thank you
There is 3 phase electricity at 400 cycles. It provided by the alternator Pryor to rectification. It also has specified voltage, like 115 volt and 26 volt systems
Not the voltage, but the current will make a fuse/circuitbreaker blow. ;) #smartassmodeoff
Alternator is for AC. AC is converted to DC via Rectifiers.
For DC it is called - Generator.
Correct, an alternator produces alternating current that is converted into DC (or Direct Current) usually through solid state components mounted on the rear of the alternator, usually referred to as a Rectifier. Therefore, it is also true for someone to say the alternator produces dc current for the system, though it is less specific, and and demonstrates a very simplified understanding of how the system works.
What does the starter contactor do
1:27 Circuit breakers pop when there to much current flowing through them.
Damn that is a huge mistake on their end.
'Excessive voltage or too much current same thing...no?
i confirm
Wow where was this shit when I needed it for A school.
Thxs naval education for a subpar course
Why light aircraft use DC.?
What is normal load should bs on loadmeter.
If the ammeter is showing neither a charge or discharge then the alternator is not working but why isn’t the battery discharging?
If the ammeter is showing neither a charge nor a discharge, then it's being charged at the same rate that it's being discharged. The alternator would still be working. If the ammeter was showing a discharge, then the alternator would not be working.
@@ERAUSpecialVFR There should only be either battery getting charged or discharged at one time right? can there be a possibility where battery is discharging its power at the same time is being charged by Alternator as well??? cos how can it happen that both battery charging relay closes and battery discharging relay closes as well??? either of them should close but not both at same time right?
0:00 : the electrical system provides electrical power to different systems...
*Thanks captain obvious*
P.S. ; this is a joke.
The fuse blows due to over amperage not over voltage lol
What happens in the event of an alternator failure? Do the systems run on the battery until it dies?
Yep!
Could you test my creation, thanks! Observe androidcircuitsolver on google
No way the voltage regulator is literally an LM317 in TO-220 package... I thought planes are supposed to be built better.
That's exactly what I thought! or could this be a mistake as well?
1:53 lol
.
Build your electrical circuits on the go! probe circuit solver on the playstore!
I tested all of the sites, and all except for 1 are fake. It's name is Gamecrook.
An ammeter with markings of six volts per division, and a load meter with three volts per division. Unlikely, and also stupid.
Yo, if anyone wants to get free coins, gold, gems, diamons, etc., they may get them at GameCrook.
Thank you
