Thanks again for watching.
Keep safe and 'Keep The Plates Spinning'
Absolutely Fantastic. This has given me such a better understanding of the fuel system. Thanks.
Thanks for the feedback Matt. Did I see you in the sim Center recently?
@@airbuswhatsitdoingnow320 Yes you did see me there, great to meet you. Once again, fantastic content. COAS passed. Your videos were a great help, thank you!
@@matthewevenden6720 I’m stoked for you amigo
Best overview of fuel system I’ve heard. Thank you so much for your work! It’s so helpful and you fill a big void in the airline training world
Thank you for taking the time to feed back. And welcome to the channel
Special thanks for explaing in energetic way😊😊
Thanks for the feedback
Thank you very much sir. Very nicely explained.
Thank you, great video, appreciate your time, effort and energy in these videos.
My pleasure!
Excellent work! Love the diagram!
Im pleased you found it useful. Thanks for the feedback
Really interesting, the diagram particularly useful to explain those extra details.
Thanks for the feedback Toby. Flight Controls Part 2 Will be available again this afternoon. Happy Easter
Wonderful presentation capt. 😀
Wow
The reason for the Nitrogen Generation System to only be for the Center Tank for the B777 is that the flash point for fuel is around 38 deg C. Since the packs are located below the Center Tank, the temperature can reach above that. For the wing tanks that heating problem does not exist. Maybe the same reason why the A320 have a similar set up
Seems logical. Thanks for taking the time to comment
Hat off, very informative indeed.
Thanks for the feedback, I hope it helped
Thank you so much for the video 🙏Really informative .
May I know what’s the reason to switch off the fuel pumps on the A320 during parking check?
Is it to avoid the pumps from overheating if there is no fuels in the tanks?
Quick question:
With the Jet Pump config, we may not be feeding directly from the centre tank to each engine, but essentially we are, as the centre tank fuel is pumped to each inner tank(?).
Should there be a fuel contamination in the centre tank, then we would be feeding that contaminated fuel to each engine on takeoff, via the Jet Pumps/Inner tanks (albeit indirectly). Am I correct when I say this, or am I misunderstanding something?
To rephrase... with the Jet Pump config, what is preventing a contamination in the centre tank from being fed to both inner tanks (and therefore both engines) during take-off?
Thanks in advance!
Good question. i guess there is a reduced likelihood given its added to a tank rather than entirely from the center?
Hi. Great videos and really enjoy the content. just paid for membership. do you have a video on fuel leak?
Hello Darragh, yes I have a fuel leak video its in editing currently.
Am I wrong or at 20:00 when you are talking about the "new" type without center pumps you should have removed the "A320 no jet pumps" title ? I am just a bot confused . Thanks
Clearly I’m talking about and have drawn the jet pump config so you can obviously ignore the no jet pump reference as it is a hangover from the centre tank pump config discussion..
Hope that’s clearer
Hi AWIDN, a question with the procedure when parking and switching the CTR TK PUMPS/XFR PUMPS off.
I understand the logic that if the MODE SEL pb was unduly selected MAN, and the pumps weren't switched off - that the pumps would continue to run and therefore if the inner tanks are full, there is a risk that fuel will be vented overboard. Similar to the IDG scenario that you describe in the briefing.
If my understanding is correct, is this a risk with the NEO/XFR jet Pump fitted aircraft and not the CEO/CTR TK PUMP fitted a/c? Since the CTR TK PUMPs don't directly transfer fuel from the centre to the inner tanks like the XFR jet pumps do?
and if so, Is the procedure the same across the fleet to keep it simple and familiar across all CEO/NEO aircraft in the fleet and avoid any unnecessary confusion with 'am i on a NEO or CEO today?'
Many thanks for your help, I thoroughly enjoy your vids and they are an absolutely invaluable resource - please keep it up!
All the best
Hi and thanks for getting in touch. Yes the risk is more with the Neo as you say and so for commonality the procedure runs through the fleet. Im pleased your enjoying the content
@@airbuswhatsitdoingnow320 Brill, thanks a lot!
What would be the reason for “ X Feed - off “ reaching gravity feed ceiling ( ABN PROCS ) . Thank you.
Just thinking practically this would eliminate any non deaerated fuel contaminating the other side..
@@airbuswhatsitdoingnow320 I was thinking about avoiding any fuel imbalance (pressure from the crossfeed line being more important than the one from the gravity line) , maybe I'm wrong.
Why Airbus decided to eliminate the outer wing tank in A321(or specifically made single cell wing tank). If it was a better design then why they provide outer wing tank in A320 Neo. Somewhere I read it was to reduce weight, but source was not authentic and reason don't look convincing. Somewhere it was explained due to double slotted flaps. If anybody know please answer.
Good question. The A321 has a different wing A319 and A320 are principally the same wing from memory so keeping the wing tank config keeps is simpler? that would be my guess.
@@airbuswhatsitdoingnow320 thanks
