FSLabs A320-X Basics: Bleed Air and Pressurization

[@davey6693]

Another excellent video. Flight simmers have a lot to be thankful for right now with the platform, but the insight from this 320 series is epic. Thanks so much BB for the time you invest in these.

[@jamesgao7019]

I know these videos are great I agree with you

[@Blackbox711]

Thank you very much Dave! I am glad my insights are appreciated 👍🏼

[@nancylee1762]

thank you very much for the wonderful video.

[@mrbassett4388]

Excellent video, best tutorials for the FSLabs A320.

[@Blackbox711]

+Mr BaSsEtT ... Thank you very much 👍🏼

[@hubermarcelo4273]

Your tutorials are the clearest I'm glad that I found your channel thanks to you now I can understand more on what's going on when I'm flying on the simulator. Can you make a tutorial about the electrical system please It's a little difficult to understand the electrical systems for me I'll really appreciate!!

[@Blackbox711]

Hi. Thank you very much. A video on the electrical system is a good idea 👍🏼

[@hubermarcelo4273]

Blackbox711 Thank you

[@aaronpeteiro6105]

Hi BB, thanks a lot for your videos, they are awesome!. Yesterday I had the opportunity to see your live stream in Twitch for first time and enjoyed alot with it. I heard you say that make this video took you two days so...thank you for spend your time making that kind of videos for us, I really apreciate that!

[@Blackbox711]

+Aaron Peteiro .. Thank you for your kind words. I appreciate that very much 👍🏼.. yes, those tutorials do take up to 10 hours work. But because of people like you it is worth it. Thank you for watching 👍🏼

[@romaincannizzaro8344]

I'm a Turnaround coordinator / load controller in MRS, and I was always wondering what was that valve which is still open! Thank you for your great video!

[@Blackbox711]

+Romain Cannizzaro .. my pleasure. Thank you for your positive feedback 👍🏻

[@technobop2917]

The Flight Factor a320 is going to come out soon!! You should definitely check it out as it is study sim and supposed to be used to train real world pilots.

[@Blackbox711]

+techno bop ... I will check it out if it is as good as they are claiming it to be.

[@واحدمنالناس-ن9م]

Black box You doing great Keep up We need another video for ELE system and related faults .

[@FlightDeckMagazin]

Thanks for uploading, very good explanation.

[@Blackbox711]

+Flightdeck Magazin Hi. Thank you very much my friend 👍🏼

[@thomasfranckaert368]

Keep making these tutorial video's please :-). Much appreciated! All the best.

[@Blackbox711]

+Thomas Franckaert .. Thank you Thonas. Much appreciated

[@thomasfranckaert368]

Was wondering though. As you commence the take off roll. Why is the pressure difference negative? Pressure in the cabin is higher than outside, so I would think it is positive no?

[@Blackbox711]

+Thomas Franckaert .. good catch there! I falsely said during the takeoff roll the differential pressure would get negative. That is incorrect. It goes to +0.1 PSI. I will change that in the video. Regards

[@thomasfranckaert368]

Blackbox711 I don't want to bother you to much, but I am just trying to grasp the system. To avoid pressure surges the pressure starts to increase during take off roll...so the pressure altitude is now lower than the airport pressure (shown in the drawing). But isn't it just creating a bigger pressure difference cause the pressure altitude is lowe then the airfield. The difference between the red line an de the green line is bigger then the blue line and the green one. I hope you understand what I am trying to say... ..Thanks. regards

[@konradstrachan]

Fascinating video - I always learn something new and really enjoy your style of teaching. Thanks so much for taking the time to share your knowledge! I do have a small question - you mention pressure surges on take off and landing, what would cause these and how does a negative pressure in the cabin mitigate this ?

[@Blackbox711]

+Konrad Strachan .. Thank you very much for the kind words. Pressure surges or 'bumps' happen because air behaves a little like water. So during takeoff/liftoff the air will move backwards causing higher pressure in the back and lower pressure in the front. The pressure controller then has difficulty measuring and regulating the cabin pressure and that can cause even more pressure surges in the cabin. Regards

[@konradstrachan]

Fascinating.. thanks for the response :)

[@jacobtang641]

U must have the sound pack huh , sound is really nice on my earbuds

[@ThomasDanielsen1000]

Another masterpiece by Blackbox - looking forward to the sequel! Just one question: doesn't the APU bleed need to be precooled? Or is it automatically at a lower temperature than the bleed air from the engines?

[@Blackbox711]

+Thomas Hjortgaard Danielsen .. The APU has a single stage Compressor, so Bleed temperature is lower and does not need to be precooled.

[@ameen10100]

Great helpful video as always. Keep it up :D

[@Blackbox711]

+Ameen Alshafi ... thank you very much. I'll continue publishing videos, so stay tuned.

[@recl90]

Hello... I have a problem with my A319 fslabs... Air Pressure on cab pressure are in 0.0 doesn't change! I have a pressure problem in all my flights... can you help with please...?

[@Blackbox711]

Did you switch on the packs and made sure the windows in the cockpit are closed and locked?

[@ayushroy2347]

When you talk about Cabin altitude, do you confirm that it is in link with ISA standards? For example, if it pressurisés the cabin at the same pressure as LDG ARPT ELEV -250ft, to figure out pressure at that altitude, it does not use real static pressure but simply ISA standards no? Thanks!

[@ayushroy2347]

Let me make it more clear: if cabin altitude is at 300ft (which means that pressure in the cabin is equal to the pressure at 300ft, If I understood it well). However pressure at 300ft is different everyday in real life: it depends of the weather, the place...etc. So how does it figure out pressure the exact pressure value at 300ft? It uses ISA standards to figure it out, right? Does it apply ISA standards from MSL (1013hPa/15degC ; which would mean that it knows that pressure at MSL is 1013hPa and that we lose 1hPa every 28ft. It is then easy to figure out pressure at 300ft in ISA standards) or does it apply ISA standards in link with current weather/pressure (The plane knows - ADRs - the static pressure outside. So does it then say that we gain approx. 1hPa every 28ft so it then figures out pressure at 300ft)? In the first case, cabin pressure at 300ft will always be the same in any plane. In the second case, pressure at 300ft will change everyday as our reference on which we apply ISA standards is not the same everyday. Hope my question is clear :) Thanks!

[@Blackbox711]

+Ayush Roy .. I did not expect anyone to really want to know this. But I was wrong 😉. OK, so here is the answer: The Pressure Controller normally uses the landing elevation and the QNH entered in the FMGC. That is why you need to fill out at least the QNH field in the Landing Performance Page. The pressure altitude is derived from the ADIRS. If the FMGC data is not available, the Pressure Controller uses the Captain Baro Reference from the ADIRS and the LDG ELEV selection. I hope that cleared things up!?

[@dajces94]

Hello, I have a small problem. I have route SIMEG M736 SALLO UM44 KOGIM DCT MAREM/N0440F360 T106 BAGMI. But I can't figure out, how to enter the waypoint MAREM into MCDU. Can anybody help me please? :)

[@Blackbox711]

+Nicer .. The numbers behind MAREM are not entered into the MCDU. Those are just fligtplann numbers (440 kts and FL360).

[@wildrover4643]

Enjoyed your live stream from monday, just as many others, it was very informative covering the temp and airco systems. I do have a question though regarding the one engine out simulation you performed, wich strangly enough nobody asked. After the bird strike in engine #1 the wing anti ice became inop. If this happens in winter ( or in the North like Canada/Scandinavia) with ice and snow conditions present, does this mean that only one engine out could end the flight quite unpleasantly? And, me being a xplane changée..., here is a link of the best, free, airport sceneries currently available. (Maybe an idea to do a madeira flight in the Ixeg...?) flyingxplane.apps-1and1.net/tourist/ Thank youfor all the effort and interesting teaching you put in the sim hobby! ( especially when you get stressed doing the Cat-tests 😅, Cool to see you than fall back to your basic flying traing/procedures!)

[@Blackbox711]

+Wild Rover .. Thank you very much for the kind words! First of all there is a way to get wing anti ice to work on the failed side by opening the crossbleed valve and switching off one pack to make sure enough bleed air is available for wing-anti-ice. This should only be done when absolutely necessary, since it could contaminate the other bleed system with smoke or poisonous fumes. Secondly, thank you very much for the link! Happy Landings

[@jamesgao7019]

hey blackbox when I've downloaded the pmdg 777 livery on the livery manager how do I use it on a flight and select the livery for a flight? i'm using the fsx steam edition

[@Blackbox711]

+James Gao .. always installs through the PMDG Operation Center Addon

[@jamesgao7019]

yes I've done that how do I select the livery on fsx by the way I have the steam edition

[@Blackbox711]

+James Gao ... the different liveries should be visible in the Aircraft Selection Menu

[@jamesgao7019]

wheres that

[@jamesgao7019]

can you make a tutorial please please

[@FlightDeckMagazin]

Read today, this pushback will part of the FlightFactor A320, looks amazing by night: kzbin.info/www/bejne/mmaQl5KFqrWbppo

[@miniena7774]

You're welcome for requesting this. :P

[@Blackbox711]

Did you request this as well? I had another request for this from AirbusfanDK :)

[@rubenarconada6138]

Blackbox711 how many fps you get normally with the fslabs?

[@Blackbox711]

+Rubén Arconada .. in P3D V3 around 40 FPS, running approx. 75% from max settings

[@rubenarconada6138]

Blackbox711 ok thanks!! did you feel a big difference between the 4790k gtx980 to your actual rig?

[@Blackbox711]

+Rubén Arconada ... not as much as I had hoped for tbh. That was quite disappointing. But I would say everything above 30 FPS is good enough to have a good flying experience in P3D V4

[@MONRFin]

Am I the only one who thinks that it's taking WAY too much time for A320 for V4 to be released?

[@miniena7774]

Yep.

[@Blackbox711]

+"Brain Explosion" .. I understand your criticism. However we have a nicely functioning FSLabs A320 in V3. At least I am enjoying it very much. I would rather wait a little longer to get a proper working airplane in V4. And maybe have the A319 coming out at or around the same time.
