Old video now but massively educational for me, now getting into x-plane. It’s fantastic to hear about the depth of realism in simulating these systems.
Super explanation! Even though I’m only a simulator pilot I love the Cessna 172 and try to learn everything about it! This was a great demo. Thanks Clay!
Thank you and congratulations. Your videos are awesome ! You must be a very good pilot, it’s clear for everyone. Your are also an X-Plane expert, we all agree with that. But, for sure, you are a very, very good teacher. That makes your videos so brillant. Your explanations are clear and concise. Please continue. We have a lot to learn.
Dude thanks so much this will help me on my PPL checkride! I had no clue that the numbers on the circuit breakers meant the amps that flow to that system. So much information explained in a very interesting way.
Great, Luke - good luck and just be sure to compare anything you see here to your flight manuals and with your instructor. Many differences exist in the sim world, as real as it is, and I want to make sure you get the best information from an instruction and other official sources.
IRL, avionic buses do not turn off the flaps, the fuel pump or the annunciator (warning) lights, they are not avionics. They are all connected to electrical bus #1 instead (C172SP POH).
Nice! when I finally make the jump to X-Plane I'll have to get the Airfoillabs Cessna 172. This sim is a great place to practice system failures and emergency checklists... if it's modeled correctly ;-)
Agreed - there will always be differences in how airplanes are modeled, but the real value comes in the “chair flying” benefits of running through checklists and mentally rehearsing.
Very interesting! I think I'd like to understand the engine a bit more. I didn't quite grasp how the spark was still being generated when all electronics were switched off. I think my confusion is in that I am not familiar with how magnetos work. I might do some youtubing to see if there are and visual explanations. Then I'll come back to this clip. Thanks!
Great presentation! Unless I missed it, you didnt show system voltage with the alt off, should be about 24 volts. With alt back on should be about 28 volts charging with pressure to make sure batt is fully charged at at 24volts. Also with stock X-plane 11 cessna 172, you cant turn off batt side of master switch without turning off alt side also. Again, thanks for presentation.
Great video, I learned some things I didn't know. One question, did you ever determine why the DME breaker was thrown? If you covered that in the video I missed it and will have to go back and review again. FYI, I love your videos, you are a very good instructor. Thank you for sharing your knowledge and experience.
Thanks DaugBiscuit! I think it might have just failed with the others, but I’m not certain I ever pinpointed when it happened. Thanks for flying along!
My instructor actually turned off the ignition and put the key in his shirt pocket. The resulting "engine failure" was not just a "throttle to idle" simulation. He'd "hide" the auxiliary practice grass strip directly under the aircraft. And we'd dead stick spiral to landing. If we were setup well for landing, then he'd give me the key back and I'd restart the engine. Or it would be a soft field landing to a full stop.
Hi Clay, awesome tutorial! I just wondering how did you do to interact (pull and push) with the cockpit breakers. I tried to do the same you did in the video but the breakers are not doing anything when I'm clicking on them. Thanks in advance for your help!
Hi Clay, awesome tutorial :) Quick question and I apologize if I didn't understand something that you've explained in this tutorial. I understood that the battery/alternator sends power to the magnetos which then sends current to the spark plug. So if I have the battery and alternator switch off, where are my magnetos getting the power from ? since the aircraft keeps flying even with the master switches off.. Thanks for any info :)
Thanks Elvis! No apology needed for good questions. The magnetos are small electrical generators that are driven my the physical rotation of the engine. So if the battery and alternator are off, the engine effectively runs independent of them since the turning of the engine powers the magnetos and the magnetos supply the spark for ignition in the engine cylinders.
Love the video. Thank you so much. I still have a qusstion though. What is avionic bus and primary bus. Like when you turn off the avionic bus we lost most of the things such as gps clock. But what would happen when primary bus goes off. What supports primary bus and what supports avionis bus? Thanks
Most POHs have a map of what equipment is tied to each bus, and it varies. I had to try each one and make a list of the items on the busses in this particular airplane.
I keep getting the volts light and I have no clue why it turns on. I’m new to the sim/flying in general, even on tutorial it sudden turns on and doesn’t turn off. I only have the yoke from honeycomb. Any help on this? I searched the manual, it says what it is but does not tell me how to solve it. Thanks
The “Volts” light indicates that the alternator is indicating a discharge. It is often seen when running a very low RPM with a heavy electrical load (like during taxi). In this case, it just means that the engine isn’t spinning the alternator at a rate sufficient to keep the battery charging. Is this when it’s happening for you? If so, try throttling up some, maybe to around 1000rpm.
clayviation it happens on all the tutorials, about 1 minute in the air, it’s starts to do this sound and turns the volts light on, yet I have my rpm at around 2200rpm as I climb to 1500 ft.
Hi Clay thank you for the video. One question, if I had to turn off one or both Avionics switches mid flight, from reading your description it sounds like I would lose lights, pitot heat and flap control (along with other things). But during preflight we test those three things after turning off the avionics switch in a 172. I must be misunderstanding something and was hoping you could clarify? Thank you!
Great question, Dean, and I’m stoked that you are thinking about this so critically. Here’s what I can tell. I can’t speak for every airplane, but in this Airfoillabs Cessna 172, having the master switch on with the avionics master switch off will indeed allow flaps to operate, just like when you preflight and pop the master on to lower flaps. If the circuit breaker for the Avionics Bus 1 is pulled, the power supply is then broken to the items listed, including the flaps. So my takeaway from this learning is that by knowing the items that are on each of the avionics busses, it might provide insight into what would be lost if those circuit breakers were to pop.
Thank YOU for the great question! The truth is, since you and I have now paused to dig a little deeper, we have that much more of an edge on understanding these systems.

Great to hear, Adrian! Welcome to X-Plane.
Everytime I find somebody on You Tube who is good at teaching and explaining .....I am a happier man .....thanks.... I subscribed
Thanks for the kind words, Jan! Lots more to come.
Good information transfer pace, calm voice, top video, thank you
Thanks, with growing insanity!

Thanks for the generous comment, Nonkelbeer! Expert might be a stretch, but I'm happy to share what I learn. :)
Very educational! I learned a lot here. This is a testament to the depth of the AirfoilLabs 172. Great add-on...
Thank you! Yes, it has been my favorite airplane so far. Well made and great to fly.
i realize I'm pretty randomly asking but do anybody know of a good place to stream new movies online?
@Gavin Titan flixportal :P
@Mathias Uriel Thanks, I went there and it seems to work =) I appreciate it!
@Gavin Titan Glad I could help :)
Awesome explanations!
Very interesting although I'm a newbie it's good to know that I don't really have to panic in case anything goes wrong. Appreciated. Thanks.
Glad you found it helpful, Billy!
Awesome tutorial and info... thank you!!
Finally I understand this. I got unsat because of this question. I feel stupid.

I fly here all the time, good for cross country time from Oahu. 2000 foot runway, such a great flight!
Sounds amazing, Kaden. So cool that you get to fly this!
Another well explained and clear video. Great work Clay :-)
thank you so much this was very helpful
Enhorabuena por el video
Wow, by far the most informative instructions on electrical systems. Keep this up!!!
Thanks Hieu!
Wow!!! Amazing video, with great details and visuals. Great Job!!!

Thanks, Stephen!
Thanks for all the Info!!! I love this!
Absolutely, Matthew! Thanks for watching!
Really a very well and nicely explained video. Please do make more like these.
Thanks, Monish. I hope to produce more soon.
It finally clicked thank you
Another excellent tutorial from clayviation.
Thanks Dave - you're just saying that cause I flew you around Hawaii :)
This was great - going in for my commercial this week. Thanks!
Best of luck with your Commercial, Rachel!
did you pass?

This is great. I'm gunna get xplane
thanks for the video and to the first question: you'd lose avionics, lights, and gauges. but your engine would stay.
Excellent video!!
Thanks for watching Ivo!

What is the inst circuit breaker can’t find it in the poh at all
Great information thank you, but in real 172 you cannot move battery to off without the alternator.
It appens that if I switch on Master ad I waste time doing something when I try to start engine doesn't start... How can i solve this problem?
Hi Clay, awesome tutorial!
I just wondering how did you do to interact (pull and push) with the cockpit breakers. I tried to do the same you did in the video but the breakers are not doing anything when I'm clicking on them. Thanks in advance for your help!
Hi jose - that is a feature that the Airfoillabs Cessna 172 has. I’m not sure that is possible in the default one.
Very good. 🙏
Thanks, Hailstone!
