Spirit airlines A320 departure from Las Vegas. ( LAS-CLE ) (very noisy PTU)

[@Frida_Fjer]

I loooove airports at night. And flying when it's (getting) dark is another special feeling 😍 Thank you. I hope you had a nice trip 💛

[@Frida_Fjer]

What is this "chew-chew-chew"-sound in the beginning on the taxiway?

[@OhioAviation]

That's would be the power transfer unit or PTU activating. It's trying to equalize the hydraulic pressure within the lines. If u listen close a few more minutes into the video u hear the pilot start the 2nd engine. Some airlines utilize a 1 engine taxi policy to help get out the gate faster and simply start the other on the way to the runway. If the taxi is short both engines will be started beforehand.

[@Roboseal2]

The V2500 has such a peaceful idle sound. That engine could put me to sleep anytime lol.

[@TeyLinds]

Sounds more like a CFM56 here.

[@Gigantic.Teepee]

​@@TeyLindsspirit doesnt use cfm56s im pretty sure

[@OhioAviation]

The twinjet has a six-abreast economy cross-section and came with either CFM56 or IAE V2500 turbofan engines, except the CFM56/PW6000 powered A318. They used both. Just depended on each individual aircraft

I told an old lady sitting next to me it was a dog when she asked what it was. She said, "I would never leave my dog down there." LOL!

I agree. And these woman u here vibing were very respectful to everyone and had some fun that we joined in on. After takeoff they went to sleep and were peaceful that's why them having fun during takeoff never bothered me or anyone that I know of

its a single engine 2 taxi... if they choose a eng1 to single engine, they could be use elec hyd pump to charge yellow hyd system and avoid ptu.

[@alliew3144]

what's that humming sound? it's kinda scary, i have to fly next week and am unsure of what's to come

[@OhioAviation]

Nothing to be scared of. All the noises you hear are perfectly natural and especially for this type of plane. Theres alotta mechanics that go on in a plane and that humming is just noise from the engine

[@alliew3144]

@@OhioAviation Thanks!!! one more question. at 3:02 what noise is starting?

[@OhioAviation]

I'm a huge aviation nut amd that noise you here at 3:02 is parts of the planes hydraulic system activating. When everything gets turned on after it's on the ground it just needs a minute to restart all systems. If you are ever worried flight attendants will be there to comfort you. I recommend a distraction while u fly and dont worry flying is very safe.

[@AniW2319]

yep, i'm going to Chicago and i'm terrified, first flight ever.

[@OhioAviation]

Your in safe hands no matter the airline. Just finds ways to take your mind off like books or a game on a phone. Ive flown plenty of times to many different destinations and have enjoyed them

[@planespottingoliver7317]

anyone knows what sound is that at 3:02 really curious to find out

[@OhioAviation]

I'm thinking it's apart of either the hydraulic system kicking in or the PTU. I'd have to look into it more as well. I've been on quite a few A320s and this was the only one where it was this talkative and everything

[@planespottingoliver7317]

@@OhioAviationi’ve also flown on many A320s, and i could say that if u sit exactly next to the wing, you could here it like 80% of the time, this sound even kicks in when the pilots switch off one of the engines while taxing after landing

[@TeyLinds]

It is the electric pump.

[@kop9379]

Is there a dog is barking? 😃

I don´t know what´s happens with this Airbus PTU, very noisy, many videos with PTU Noise on Pushback, Takeoff and Landing.

[@yenvornyen8665]

[@perry_the_liu]

The PTU basically tries to equalize hydraulic pressure of the (I think) 3 hydraulic systems. 2 of the systems are powered separately by each engine and the 3rd system is powered by APU and emergency systems. When one engine is running, only 1 of the hydraulic systems is powered so the hydraulic pressure is different between the 3 systems. The PTU kicks in to try and equalize the pressure and it does that barking sound when in action. According to another person's comment, the PTU went on for super long in this video because the pilots did a single engine taxi to runway and they didn't activate the electric pump to pressurize the other hydraulic system which causes the PTU to be active the entire taxi. The PTU stopped when the other engine finally got started.
