737NG Fuel System explained | Real 737 Pilot

[@libnus1125]

I have seen no one else that explains it so clearly. I love the raw nature of the videos in the sense that you can just explain it with the pmdg documents provided and the sim right up next to it! It is absolutely fantastic and you are extremely knowledgeable its just extremely entertaining and fulfilling to watch and learn from them. 5 or 6 years ago when I started flight sims I feel like I could only dream of having such detailed explanations of each individual system. Thank you!

[@A330Driver]

Wow, thank you!

[@dusanmirkovic1915]

In 2003 this type of detailed information's was available only at pilot trainings. Same year I was scavenging for any kind on FCO manual and for outdated SID and STAR charts. Explanations of this caliber was a dream. Tbh it still is. You are doing a great job with this videos. Not only you are knowledgeable about this but you reveal a secret. You love this job of yours :) Congratulations for job excellently done.

Even ten years later, around 2013, when I finished school and started getting into the "serious" aviation business, and not just simming, this kind of information was really still missing. There were many great channels coming along around 2016'ish, but I thought at least on the 737 something like what I'm doing here was still missing.

These videos are amazing and add greatly to the experience of flying the PMDG 737 in MSFS. For someone fairly new to airliner simulation like myself, the whole series of 737 tutorials and livestream flight videos have been a great learning experience. Anyone that happens to stumble upon this video and hasn't seen 737NG Driver's, earlier tutorial videos, the back catalogue is an incredible resource for anyone who has bought the amazingly priced 737-600, but are new to "study level" aircraft. If it wasn't for Emmanuel's videos, I'm sure I would have given up in frustration or just not reach a point where I could do a successful flight with some reasonable level of realism.

[@A330Driver]

Thank you so much for your nice words! That's exactly why I'm doing this!

[@marcho74420]

Hi. Just a small note. When you put the fuel lever to idle, the spar valve will go bright then off, the engine valve closed light will remain bright due to the HMU not opening the valve. If it did you would have fuel spillage putting the fuel lever to idle on ground. Also we can transfer fuel from any tank to any tank on the ground but that is for maintenance personnel only. Just to complete your story. Great explanation though and very clear.

[@byronmcduffy3485]

As always, brilliant work. I know how much work these take so thank you very much and keep them coming.

[@A330Driver]

Glad you like them!

[@MrOsvaldoFreire]

On models with Nitrogen Generator, you can run the center tank dry.

Great video 737NG Driver. This basic overview is exactly what I was looking for. Thank you.

[@almightyIrie]

OMG eins nach dem anderen dieser wundervollen in-depth videos.. like bang bang bang here y'all go!! Loving that, matter of fact loving you for that!

[@Stucun84]

Thank you so much for these systems videos..! Much appreciated!

[@A330Driver]

You're very welcome!

[@fl3604]

yes please..we need lessons about systems :)

[@MentalAviation]

amazing content thank you very much

[@Ztbmrc1]

Good explanation! Just 1 question: the arrows on the diagram on the left, are those valves that prevent fuel flowing in the direction against the arrow, so fuel flow only possible in the direction indicated by the arrow? And the apu fuel pump has no separate switch, so I guess it is switch on when the apu switch goes to the on position? And of course switched of once the apu botton goes to the off position.

[@melvinmathew6027]

Hi, Cross feeding is possible in 737. Why did you say that fuel cannot be transferred between the tanks?

[@A330Driver]

Hi, you can feed any engine from any tank, but you can NOT transfer fuel between tanks. That's all the cross feed does.

[@HK-yh6gj]

Hi Emanuel, really good videos. Thank you for all. One question is where I can download the diagram of the fuel system and all the other diagrams in your videos? Thank you

[@A330Driver]

It's not available for download I'm afriad. These are from the FCOM that PMDG delivered with the 737 NGX for FSX back in 2011. They are no longer included.

[@aarndub0760]

I have 3 questions 1. Are the ac pumps only in the left tanks 2.where are the fuel boost pumps located and is there a way turn them. On or off 3. An what is the RH pump switch i saw this on a checklist not sure what it ment. Thanks for the great video anyways

[@A330Driver]

1) AC Pumps are in every tank 2) Only the AC Pumps are switchable by the pilot. 3) I guess it refered to pumps on the Right Hand side of the fuel manifold, so Main Tank 2 and the right Center Tank pump.

[@aarndub0760]

@@A330Driver so how would you turn on the ac pumps ifvthe pilots are the only one that can turn it on

[@instinctz5796]

Any chance I can get in touch with you to talk about pmdg more privately and if I could get access to your pdf by any chance it would be great 👍

Hi, join my discord for a more private conversation. The manual I can not share I'm afraid since it's under copyright.

Amazing video. I have a question to ask that is not directly regarding the fuel system but rather your operations. Why does your airline during preflight turn on the fuel pumps immediately instead of waiting until just before engine start? Thanks.

[@iiCautious]

Most likely done to check for any leaks that may occur

[@SSAviation737]

@@iiCautious Yeah I think that's it. I think he told me that recently. Thanks!

[@Nemura12]

Amazing video. Very little likes and views. The mayority just want to know the basics.

[@A330Driver]

Yep, that's how flight simming is. It mostly goes like this: When I think I've done a great video on some not-so-publicly-known things like UPRT, etc. people just don't care and don't watch it ;-) But some of the stuff, like these systems videos or the learning to fly on VATSIM series, I just do because I *want* to do them, not necessarily because they generate the most views.

[@jschwartzmier]

Should we balance if we have an imbalance and still have center fuel?

[@grazianospagni1116]

Where I can find the pages of manual of the PMDG 737 Thank's

[@Lazysloth85]

When the APU is running from cold and dark I notice simmers use the left AFT pump, and on a turnaround they use the left FWD. Why is this and does it really matter?

[@iiCautious]

The Left Aft is DC powered which means the apu is able to receive fuel via battery power during cold and dark start up and is kept this way till the plane is ready to go. As for turn around both left aft and fwd could be switched on to provide fuel. Once the apu is running and generating power the aircraft has AC power which is enough to supply all electrical systems. This may differ from airlines SOP

I can’t get my 737-9 past 64percent full of fuel. Can anybody help?
