The Piper at 1:08 crashed in 2018 because its wing fell off, killing student pilot Zachary Capra and FAA examiner John Azma. As a result of this crash, Embry Riddle now only uses Cessna 172s and Diamond twins.
Idk crazy shit can happen like microbursts. Prolonged stalls or spins might also do it kill the engine with the pump off.The fuel pump also probably increases fuel pressure so If an injector/line is semi clogged or the engine is running rough it might get you to an airport.
I don't know how many other students do this but I was always taught to use the fuel sump before checking the fuel quantity, so you can pour the sampled fuel back in, just saving that little bit of $$ :)
You said we use fuel primer to inject the fuel staight into the cylinder prior to engine start. Beforehand sorry for possibly stupid question, but what happens when we do not use fuel primer? As far as I know, the fuel in all cases is injected straight into the cylinder. Where is the difference and how does fuel primer help during cold operations?
Well, without using a primer you may not get a successful start up of the engine eg. the engine will be less prone to firing. And during cold operations because of the more dense air, the ratio of air to fuel is greatly increased and you'll need more fuel in each cylinder for effective combustion to take place to fire the engine.
Only in fuel injected engines is the fuel injected straight into the cylinder, in carburetted engines it is atomised and mixed with air upstream of the cylinders and enters them through the intake valve
Thanks, this complements very well what I'm being taught in my flight school. Just one question: Id I'm not mistaken, the fuel exit from the tank to the exit it's not on the tank's lowest point, but a little bit above that. Why is it ?
G'day. I'm reading directly from by textbook here... """In most fuel systems the outlet pipe which carries fuel to the engine stands above the bottom of the tank. This arrangement is called a stand pipe, and it ensures that some unusable fuel will remain in the tank to ACCOMMODATE any CONTAMINATION that may be introduced into the system. """ Hope that helped :)
Thanks for commenting back! With that being said, I haven't flown anything newer than a 1985! Just wanted to share my experience in case there were some student/private pilots watching that may have experienced the same!
You want to drain enough fuel to be able to clearly see any water and verify the correct fuel type was used. If you put the fuel back in the tank, you have nothing to loose and everything to gain. Don't be shy!
In level cruise flight of most aircraft, one tank drains quicker than the other. This also causes a weight imbalance for the aircraft affecting control. So, during flights exceeding 1 hour, the pilot will switch tanks for a period of time to keep these balanced as much as possible. Large transport jets have a computer based fuel system (I believe) which does the same thing automatically. For takeoffs and landings, the selector must be in the "Both" position and most definitely if the pilot is practicing steep turns and other such movements when the wings are not level or for AG spraying (Low altitudes). Many pilots have died for not managing fuel carefully.
3:24: uh huh. Ok. Wait. What. Ok stop. Stop. Stop. Bruh. Stop. STOP. WHAT ARE YOU DOING! YOU DONT NEED THAT MUCH!
HAHAHAHA

Awesome explanation, thank you 🙏🌹
Minutes 3:41, much corrosion in that panel next 100 hour inspection. we have to work it 🤔😎💪thank you awesome video Sir.
Yes when gravity fails you need a fuel pump.
It’s probably for spins or negative G manoeuvres and other things.

The typical carbureted C172 typically runs for about 2 seconds when inverted. Source: Sporty's Intro to Basic Flight Maneuvers.

I normally just drink it before my flight
@@kevinhouston1484 bruh
Great video as always thank you so much
Fact check: Carbureted Cessna 172 models have fuel primers
Thanks, this is an aweosome video
Well this was something I haven’t seen before, putting the drained fuel back on the tank!
That is using a filtered sumping jar. Don't try it without a filter.

That’s also why you want to sump from the lowest point closest to the fuselage first.
I love to drink the fuel lol it looks so delicious

Thank you very much 5/5/2020
I'm going to need a second mortgage for that fuel drain
Very interesting information.. thanks..
Great video, but all c172s I've flown have been equipped with a fuel primer...
Thanks, Kyle. That was very common on older model Cessna aircraft. The new fuel injected do not have a primer, however.
Thanks for commenting back! With that being said, I haven't flown anything newer than a 1985! Just wanted to share my experience in case there were some student/private pilots watching that may have experienced the same!
Thanks for that! We love bringing pilots of all experience levels together, and hope that our work can help everyone learn a little something.
Kyle Cooke I fly a 172s it doesn't have a primer. The 172n carbonated model does
Ok.
Perfect video
It's time to go inverted with the Piper Arrow. For safety reasons of course 👍🏻
That guy drained a lot of fuel during his inspection, or is it me who hasn't been draining enough?
I drain so i have a full cup when i'm done with them all.
Something… I don’t drain that much either, we only drain a small amount.

I just get some for the base
very interstanting video, very simple thanks a lot
Thank you!
Good video
when do we use those fuel selector options like left and right?
Gravity never fails
Why would you _not_ want to draw fuel equally from both tanks at all times?
In level cruise flight of most aircraft, one tank drains quicker than the other. This also causes a weight imbalance for the aircraft affecting control. So, during flights exceeding 1 hour, the pilot will switch tanks for a period of time to keep these balanced as much as possible. Large transport jets have a computer based fuel system (I believe) which does the same thing automatically. For takeoffs and landings, the selector must be in the "Both" position and most definitely if the pilot is practicing steep turns and other such movements when the wings are not level or for AG spraying (Low altitudes). Many pilots have died for not managing fuel carefully.
If you had say a drone strike and there was potential debris inside the wing tank you can isolate that to ensure fuel flow from your good tank.
For those who said they don't put the fuel back in the tank - what do you do with the leftover fuel in the sump?
Drink it
dump it
Thank you!!!!!!!
hi😇
Hello AVT II 👋
Excellent
very helpful
*I try not to judge people for how much fuel they drain during pre flight, but I think I just drain too little maybe..* 😂
He drained too much
what kind of fuel of the Cessnas?

Hey where is Ep. 4?

Thx I'm trying to be a pliot
It’s not a good practice to top up the tanks with the drained fuel!
That’s the entire purpose of the GATS jar. It traps contaminants so you can put it back into the tanks.
As long as you don't put back water or contaminant, nothing wrong with it!
