Packs ON or OFF for takeoff? Advantages and Disadvantages | Real Airline Pilot

[@ItsLafar]

I learned something!! This types of videos are the ones I enjoy the most. Always trying to learn more about airplanes! Thanks mate.

Packs on….so I have less to do after takeoff 😂

[@AlexdAviator]

official airbus SOP are being changed because of this comment

[@musiqtee]

Packs on - I need my gaming PC to heat the room during takeoff and initial climb…

[@fata__morgana]

​@@musiqtee Legit answer for winter

[@musiqtee]

@@fata__morgana I’m Norwegian (no, not _that_ Norwegian…), winter is forever around here… 😅

[@ifj.kosagabor]

Same

[@criancaanonima]

At easyjet, we always perform packs off takeoff, unless it's really hot or really cold

[@martinstofko]

Great video as always, thank you! I was wondering if you would do a video on noise abatement procedures in Europe and US? I am curious what is realistic.

[@A330Driver]

Will do!

[@guiduz3469]

Those pills from an experienced pilot like you are really gems!

[@ilarikousa1500]

Finnair would do packs-off takeoffs as SOP every time for the longest time, but switched to by operational necessity only after they discovred increased wear to the packs

[@Quotenwagnerianer]

In the 737 I always do Packs on, because I don't have a copilot to remind me to switch them on again. It happened to me quite a lot that I didn't notice that they were off until I was at FL200 and the Cabin Pressure warning horn went off. In the Airbus the aircraft will tell you to switch them on again. Just like you said in the last part of the video.

[@guiduz3469]

there's always check lists that serve as reminders. packs off are a must for many airliners in some specific weather and runway conditions.

Thanks for doing this video - pretty much answers my questions especially the one about vs. the 737NG

[@timothypropst238]

Takeoff with the APU on. Bleed valves are closed and APU supplying bleed air to the pacs. Same thing as pacs off.

[@daveorr5858]

As usual I learned something well done

[@DonSWG]

Thanks for this video Emanuel! I’ve been wondering about this subject. I do have a question (perhaps might be a good topic for a video?): When would you use the Force TOGA option in the EFB performance calculator? I’ve never used it, and I’ve never been given a full TOGA takeoff by default yet, so I really don’t know the context for why you’d use it. Thanks for the content, it really is fantastic!

[@A330Driver]

Hi, mostly when windshear conditions exist or if any maintenance procedure requires a TOGA takeoff instead of flexing. The MEL might also have some items where TOGA might be required.

[@alexanderharris4216]

Very very interesting discussion! Vielen vielen Dank dafür!

[@allanthomson7181]

Great short videos, thank you. Would you do one on North/South flight levels please.

[@richardswede]

Brilliant 'Again'. Thank you sir.

[@aaryansharma9878]

And what about packs on/off during landing? I saw a video where pilots landed with packs off

[@-Luke-]

Thanks for the video Emmanuel! When do the packs normally get turned on again?

[@-Luke-]

Hey! Just saw your new video :) Thanks a lot!

[@yeagerconsulting9217]

Awesome video thanks so much for sharing! I've been flying the Fenix A320 alot And I definitely appreciate knowing more information. Do you know if Fenix Has modeled the performance differences between packs on and off Engine characteristics? I have not been able to notice any difference but I haven't done any type of quantitative test either.

[@Chromatic3000]

Great video! When do you turn them off for takeoff and when to you turn on again?

[@NightingaleVictor]

Typically, anti-ice usage on takeoff is when you’d leave them off. Once you are clear of clouds at a low altitude, anti-ice comes off, and packs come back on. But packs come on after takeoff regardless of anti-ice - if you want your passengers to be able to breathe in a pressurized cabin! 👍🏻 Edit And this is to save fuel on takeoff by not redirecting air from the engine to the cabin! It saves money for the company and saves Earth haha 🌳🌎

[@pedrofernando8336]

You turn em off when entering the runway and turn on after thrust reduction, one at a time and 10 seconds of espacement

[@BenjiGator23]

Great video! Question- if I do a packs off takeoff, how long after takeoff should I turn them on? Is it at the thrust reduction/acceleration altitude?

[@PBW891]

He said within 40 secs after gear retraction.

[@ahmadsamir7772]

In Airbus pack 1 on after thrust reduction and 2 after flaps retraction to avoid excessive sudden pressurisation

[@KWpilot]

So what about bad weather would you leave them on then?

[@A330Driver]

No, what difference would it make?

[@KWpilot]

lol lots of people in aviation tell me that I should turn packs of for takeoff with bad weather for example rain or big storms?

[@KWpilot]

Also please can you make a video in the fenix about when you should you anti ice and when you shouldn’t?

[@Retainer_98]

Airbus really thought about everything

[@dijr0]

Hi Emanuel, i just want to ask when Im doing a PACKS-OFF takeoff and when turning on PACK 1 after setting climb thrust, why is it necessary to wait 10 seconds after turning on PACK 2?

[@johneveridge3714]

Surging

[@tomstravels520]

So the cabin pressure doesn’t rise too quickly too suddenly

[@saytoga]

After takeoff, at what altitude you turn ON the PACK1 and PACK2 in the A320?

[@A330Driver]

You turn them on once the engines are in climb thrust. Ensure ten seconds between the two packs.

[@yanniskouretas8688]

Does the ECON switch of the A321 plays any role - or it's only for when there is not much people in the cabin (I think less than 160 but I can't remember right now) thus the air cond unit doesn't have to work in full capacity ?

[@DrNo-fj2sy]

great

[@kal-jd6co]

So just to reconfirm to see if I'm correct or not, If I'm taking off a runway with a full length of about 5800ft, alongside maybe flaps 3, I would prefer to do a packs off takeoff, for the additional performance benefits associated with it?
