Good luck!

[@Joyplanes]

Yes, the vacuum pump would've taken me some extra work but again, there are many details missing, like the fresh air intake to the cabin, how the magnetos work, a detail view of the trim mechanism and the Yokes and how they work with chains, etc. it was going to make the video also too long and I would still be rendering :).

First time on this channel. While I was watching this video, I've felt like I was watching a Discovery Channel program. Absolute monumental level of work and such a simple, interesting and informative result. I've had my eyes glued to the screen all the time like a small child.

[@ModelBuilders]

Really impressive video. I work as an aircraft mechanic I (not alone) maintain about 15 172s and 40 152s that’s my day in day out. You got this pretty much spot the heck on man. Couple little details here and there but this is pretty accurate. I’m not going to nit pick because this is a really good and informative video. You only can notice things that are off if you stare at them all the damn time. 10/10 impressive!!!

[@eclectichoosier5474]

I only saw one factual mistake. (About fuel injection.) For a video like this, that is truly impressive.

[@ArmaGuyz]

So I take it your Training videos back in 144 were also from the 70s and understand just how badly the AMT schools could use this. We are watching material from when I our Instructors went through School 20 years prior and that's ridiculous.

[@joelramirez2846]

Have had my PPL since 2015. I consider myself a visual learner and even though I’ve read material on the systems of this planes and how things work on them I still didn’t understand how certain systems worked until watching this video. Thank you so much for the time and effort you’ve invested to provide us viewers with such great material!

[@eclectichoosier5474]

Very good video. You got all the basics spot-on. One thing that might be different from what you showed would be that on newer planes, they put the landing and taxi lights on opposite wings. In much older 172s, they may have the landing light on the nose, under the propeller. One thing that is slightly inaccurate is that the fuel injection system does not use electronics to control fuel flow. The pilot is in complete control of air and fuel. The system is pressurized and a constant stream of fuel is injected into the manifold, but only sucked into the cylinder when the valve is open. The electronics are only used to monitor fuel flow and report it on the display, so the pilot can adjust as necessary. The engine can run even if the electrical system fails completely. (You covered that part correctly when talking about magnetos.) A minor quibble is that you call the control cables "wires." The cables are made of wires, but they are multi-stranded, like steel ropes. Even if a few wires break, you won't lose any control, and in fact, having a few wires broken in a cable is acceptable, depending on how many, and where they are broken. (I realize that is outside the scope of the video, but if people think it's a single "wire," they may get the impression that if one breaks, the plane could lose control.) Finally, while 100 octane Low-lead fuel is standard, many engines allow the use of unleaded fuel, some as low as 91 octane. (Alcohol is not allowed to be blended into the fuel. Some engine manufacturers allow a tiny amount, but you cannot use the 10% ethanol fuel from common gas pumps.) 100LL is still standard because a lot of older engines require it, and keeping different grades of fuel in stock is very expensive for airport owners. Again, outside the scope of the video, but people may find it interesting.

[@patricksawyer9779]

Gonna have to correct you on the fuel injectors... most fuel injection systems in general aviation use are mechanical units, with little to zero electronics involved. There’s some flow rate and pressure sensors, but those are used to drive gauges in the cockpit. Fuel metering is driven by a fuel servo mounted in place of the carburetor and uses mechanical, pneumatic, and fuel pressure forces to determine how much fuel is delivered to the injectors. Said injectors are continuous flow units which deliver fuel all the time to the intake manifold just before the intake valve, but it is not atomized for use in the engine until the intake valve opens. There’s some interactions there that I understand the concept of, but have trouble putting into text without an image to help explain.

[@aryanterror88]

@@miporschethe Continental IO-360-KB engine in the newest model can do 195hp

[@eclectichoosier5474]

The flow rate is a pressure sensor. A clogged injector can actually indicate a very high flow rate because the pressure goes up.

Thousands upon thousands of airline pilots got started right here in a Skyhawk, including myself. I miss it. I’ll have to go rent one of these someday and see if I still got it! Manually flying an airplane low and slow is fun.

[@officialbritishtaxpayer5609]

I think that anyone about to take a ride in a light plane for the first time should watch this video. Speaking from my own experience, that first ride can be bit nerve wracking so knowing about all these systems and how the aircraft is put together is very reassuring and this video makes it interesting too. Excellent! I was lucky to be fully briefed when I took my first flight and forty years on, I am still enjoying every moment of it.

[@hermanfeeblebottom5002]

This is a very well done description of this aircraft; one of the best I’ve seen. The creator offered one mistake, however, having to do with the pitot/static system and how it measures airspeed. Air doesn’t flow into the pitot tube, strictly speaking. Instead, as the aircraft moves forward, the pitot tube senses the pressure of the air impinging from directly ahead and compares that with the static ambient pressure it senses from the static tube. The difference in pressure works on a bellows and crank mechanism in the airspeed indicator to display the aircraft’s airspeed, or IAS. IAS must be corrected for altitude (i.e. outside air pressure that varies with the airplane’s height above sea level) and temperature (an indirect measure of air density) to yield true airspeed (TAS). Often there is a little sliding scale in the airspeed indicator (ASI) that the pilot can adjust according to the outside air temperature (OAS) to give a direct reading of TAS.

[@Joyplanes]

Thank you for the correction, indeed it doesn't make sense that the air "flows" but the pressure created by the speed is what's measured as you said. What I wanted to show is that the pipe where this pressure is retained goes to the respective instruments.

[@kuckoo9036]

Noticed that, too. Figured such a description probably goes beyond the scope of of this video, which is excellent. Indeed, you can make an entire video just on the pitot-static system and the associated instruments. One can go into quite a bit of detail just on how the instruments themselves work, with the gyros, diaphragms, mechanical linkages, etc.

[@andrewlalis]

@@kuckoo9036 ERAU has some fantastic videos about the pitot-static, gyroscopic, and vacuum instruments.

[@eclectichoosier5474]

Well, if we're being technical, it flows in.... a tiny bit. Then stops. I'm more concerned about the size of the hole that was rendered into the tube in the video. It looks like a pitot from a 737 :)

[@holl0918]

Fantastic work! This is an excellent overview of the major systems of a C172. Pretty much everything is spot on. The fuel servo which meters fuel for the injected engine is also mechanical, not electrical, but automotive injection systems are electrical so that's an easy one to miss. It has a venturi similar to a carburator which regulates the pressure in the fuel line between the engine driven fuel pump and the distributor on top of the engine (aka "fuel spider"). Also, the firing order for Lycoming engines is 1-3-2-4, with 1 being the front right cylinder and 2 being the front left. Continental engines have cylinders numbered from back to front, opposite of lycomings. I think the firing sequence animation just got a little confused as it is running backwards.

[@billyrowe0064]

[@alechendryx7023]

Best video I've ever seen on something like this. Textron should hire you or pay you to use this. I do want to mention something. Most new planes with the computer screens have eliminated the vacuum systems on the planes and the backup horizontal indicator is electric or even new ones are small digital ones with computer screens and a backup battery. Go look at a Garmin G5. New Cessnas don't have vacuum systems. The old planes with vacuum driven gages, of course, still have the systems. Many owners are converting to all digital and LCD screens like you show and eliminating the entire vacuum system. Maybe someone mentioned this before, but I didn't scroll thru the comments. In the end, absolutely incredible effort on this. I'm sure you learned so much. This type of skill should be invaluable to some company. JUST WOW!

[@swisstraeng]

Additionnal details 17:30 : Stall Indicator which doesn't seem to be modeled in this video, is often essentially a switch that is pushed up or down depending on the angle of the incoming airflow. It will simply play an audible alarm on a speaker inside the aircraft, or also often directly into the headsets of pilots through the audio panel. Some aircrafts also have a stick shaker that is generally linked to the speed indicator, to warn that a stall is near. 17:33 : Pitot tube often have a smaller hole at the rear to get rid of the water, and there is often two pitot tubes linked to two separate speed instruments for redundancy. 17:43 : The static ports are extremely often found on both sides of the fuselage, not only the left side, and they are linked together. This is to equalize pressure from the left and the right side of the aircraft, to get more accurate readings. Generally they are placed around the beggining of the tail of the aircraft, to be less impacted by speed. Some static ports are also heated, comparable to the pitot tube. 19:56 : Electrical wiring is now Copper wiring, insulated in PTFE (teflon), and are generally white in colour, and have unique codes printed all along to quickly find them on the aircraft's schematics. Large copper wires, such as the ones used for the starter, used to be sometimes made in aluminum to save weight. This is often removed and replaced by copper wires today, as aluminum loves to make corrosion over time, potentially creating an electrical fire. Extra notes: The entire interior of aircrafts is now made of fire resistant materials. Those materials can burn as long as you keep a heat source near them, but they can not continue burning by themselves. Essentially making fires in aircrafts impossible if they are not fueled by fuel, oil, or if heat is continuously supplied by electrical wiring. Circuit breakers are not very advanced, they generally trigger using a thermal mechanism, but they do not detect faults if it is not over current consumption. Or do any kind of active monitoring.
