5:23 I love that engine throttle change!

[@sla31]

Thanks for watching my friend!

[@l33VI08]

Skylite Productions no problem!

[@dlbrittain1976]

beautiful CFMs doing their job

[@sla31]

Thanks for watching my friend!

[@kpov2533]

I loved the roar. Beautiful sounding takeoff.

[@sla31]

Thanks for watching my friend!

[@bigd-1-channel514]

Cool, loved the low clouds and rain and the layers of clouds after takeoff.

[@sla31]

It was a very scenic flight wasn't it? Thanks for watching my friend!

[@FlyersAviation]

What a departure and that engine buzz tho :D

[@sla31]

Thanks my friend! I'm glad you enjoyed it!

[@JesusReigns777]

The sound 😍

[@matthewnisbet7354]

I love Southwest!!!💛❤️💙

[@jeffsimanson4251]

Keep it coming up now I love it so so much keep it up

[@tb905-b2o]

Great to have full thrust for a long time....usually after 1000 ft the engines are slowed down....4:01 Can't wait to get back in the air.

[@aviationmaliq132]

The Big T they have to be under 250kts under FL10 so the cut back is slowing down to prevent I think

[@sla31]

Thanks for watching guys!

[@zyalixwho]

@@aviationmaliq132 sorry for late comment but they reduce power at around 1k feet for fbo/airline purposes, airliners dont want to overstress the engines and it gives them less maintenance costs

[@jeffsimanson4251]

I love that engine sound loveit

[@davidadcock8717]

Maybe I'm a little ancient, but a Southwest takeoff - especially from Love Field - sounds like FREEDOM!

[@leezinke4351]

Great video!

[@JohnAckerman31]

I have wondered what makes an airplane engine buzz like that. It’s funny because when you takeoff, the engine buzzes, then after a while it goes away. I would love an answer to this interesting question.

[@sla31]

That's a great question, and actually has a pretty simple answer. During takeoff and initial climb is when the engines are running at full power. When at full power the fan blades are, of course, spinning faster than at any other time during flight. The buzzing, or roaring sound that you hear during takeoff, is a sound caused by the tips of the fan blades spinning faster than the speed of sound. What you're hearing is many small sonic booms, caused by the tips of the blades moving faster than the speed of sound. After the initial climb, once the air starts to get thinner, and less power is used, the sonic booms go away, because the fan blades are no longer spinning faster than the sound barrier. Thanks for watching my friend!

[@MartinNeep]

Actually, the sound doesn’t dissipate because the engine is going slower. At typical takeoff weights and temps, a -700 derated to 20K will takeoff with 83-88% N1. As the aircraft climbs and the EEC gradually increases the climb thrust limit to 24K, N1s will top out at about 98-99% N1. Typical cruise power at moderate weights and a cost index of 30 or less will be 85-88% N1. The real reason the sound diminishes during the climb is simply because the air density decreases. Sound waves cannot propagate so easily in thin air and so the intensity of the sound is attenuated.

[@MileHigh_Aviation]

Awesome video man

[@sla31]

Thanks man!

[@Miftahjaya96]

like the engine buzz,,,,nice video Sklylite Productions

[@sla31]

Thanks my friend!

[@shauncleary4506]

Fantastic 😀 no better sound

[@sla31]

Thanks for watching my friend!

[@joecarter5018]

Do they have meds that will take away the fear of flying?

[@bigd-1-channel514]

Go to the local airport, and get an introductory flight in a Cessna. You will have fun, and never fear flying again.

[@Dooluh_]

They have Dramamine at airports which really work for motion sickness. I have really bad anxiety but a 1 hour flight from Dallas to Lubbock Texas was smooth and took away the edge I had for my next couple of flights. Try shorter flights. At least that worked for me. Also get an aisle seat if you are claustrophobic. I am but the aisle seat helps alot. I hate middle seats and window seats. I start to panic.

[@sla31]

Both good options! Thanks for watching my friend!

[@nixaviation]

Love those CFMs 😍 What seat was this filmed from?

[@sla31]

This was filmed from seat 4F.

[@joetexas1546]

Great view! Thank You!

[@sla31]

Thanks for watching my friend!

[@HurricaneJahya]

5:28 the familiar sound everyone knows...

[@sla31]

Thanks for watching my friend!

[@lol-ug2ry]

CFM56-7B sounds amazing

[@sla31]

Thanks for watching my friend!

[@sport2ful]

Is Southwest the only airline to fly out of Love Field?

[@Pedrito2513]

Nope, Alaska and Delta also fly out of Love Field.

[@MC-wf7nw]

Alaska. Horizon. Delta. Skywest. Southwest.

[@FLYBOY2935]

I have seen these airlines at Love Feild, Southwest, Alaskan Horizon, Alaskan, Delta, Virgin America before the Alaskan merger, and Allegiant (flying a charter flight.). Occasionally you’ll see some NAVY aircraft as there is a Naval ramp at the airport.

[@sla31]

As others have mentioned, there are other airlines that fly into DAL. Thanks for watching my friend!

[@taxiviaalfa]

I'm pretty sure Alaska does actually

[@inflightreports]

Very good quality! What camera is it?

[@phaoast4524]

iPhone 11 Pro, it’s in the description

[@sla31]

Phaoast beat me to it. Thanks for watching guys!

[@inflightreports]

@@sla31 Jeez. That looks like a 1000 dollar sony camera or something.

[@sla31]

That's true, but look at it this way. Most people buy an iPhone to use as their phone/handheld computer. They cost over $1,000. My iPhone 11 Pro, since I wanted the larger hard drive, cost me over $1,400. But I don't look at is as buying a phone. I had a perfectly good iPhone X that had no issues. I looked at is as buying a $1,400 camera, that also makes phone calls haha. One of the reasons that phones are so expensive now, is because people expect them to have awesome cameras. And awesome cameras are expensive. When you buy a new phone, one of the reasons it's so expensive, is because of the cameras. So, if you look at it like that, it should be just as good as a $1,000 stand alone camera.

[@albertod4161]

Southwest airlines for the win!

[@nicks4597]

Great way to travel during covi19. After all this ill be more affraid to get on planes. I love to fly fly though oh well. Stay safe..

[@RenoVaTio1958]

I fly Southwest about 15 flights a year what a wonderful airline hope to make A list one day

[@sla31]

I hope you get there my friend! A-List is pretty nice!

[@alyssalebeau3661]

Can anyone recommend a seat on a 737-800 that is best for engine buzz?

[@sla31]

For engine buzz you just want to be in front of the engine. As long as you are in front of the engine blades, you’ll heat it. I prefer row 4 on Southwest’s 737-700’s. The 800 though. Not sure. I don’t fly southwest’s 800’s very often.

[@zokaya10]

and thank god im good at hearing

[@cokecansandwinglets5783]

Just out of curiosity do you happen to have any elite status on the airlines?

[@sla31]

I do. I fly enough to maintain status on two airlines. Currently I have status on American and Southwest. Gold on American, A-List on Southwest. If I flew only American I'd fly enough to hit Platinum Pro.

[@joeppg]

Can I have some of your milage 😂?

[@jacksonpeanutbutter8862]

whats the seat number?

[@sla31]

4F. Thanks for watching.

[@zokaya10]

seat 6A is the best for me

[@highcrimes9153]

Cool.

[@sla31]

Thanks for watching my friend!

[@official_southy]

When the coronavirus stops,you maybe should go fly from another state and and land at love field in a different direction than from that video.(If you don’t know what I’m talking about,just ask me so I can tell you in some different words.)

[@sla31]

I understand what you're saying. I actually had flight scheduled into DAL from other areas, but I cancelled them because of the virus. Once this is all over I'll be back in the air though. Thanks for watching my friend!

[@l33VI08]

The Coronavirus will never stop, it will just keep going. Just like the flu kept going.

[@RasheedRasheed-d4g]

❤❤❤❤❤❤❤❤❤❤❤🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰

[@taxiviaalfa]

Sounds like a de-rated takeoff

[@kwmproperty7379]

Empty plane, rocket take-off

[@sla31]

This was actually filmed quite some time ago. I think the plane was pretty much full. Thanks for watching my friend!

[@timelapseinsanity178]

Am I the only one who doesn't like the buzz of the engines?

[@tb905-b2o]

yep...LOL

[@bburkie55]

No you're not. If you don't like the engine buzz sit behind the engines. The buzz is caused by the fan blade tips moving faster than the speed of sound during their rotation and is only audible when you sit in front of the engines.

[@sla31]

You're definitely not the only one, but you may be in the minority haha. Thanks for watching guys!

[@dannywilliamson3340]

That sounds like about 80 hz at takeoff (kzbin.info/www/bejne/pJnGZahso6-Gjc0)

[@sla31]

Thanks for watching my friend!
