Delta Airlines Airbus A319-114 Pushback & Engine startup. (MKE-MSP)

[@vibranthang13]

i love the sound of the start and the smell of the fuel

[@ZacharieGaming]

I just love the sound of the engines when they start to growl.

[@CngDelta757]

@Iluvbadgers For the sound... its a hydralic pump called the PTU (Power transfer unit) and they previously did safety announcements before the vid

[@jesusgutierrez4581]

2:12 lovely PTU

[@vibranthang13]

i love this engine sound

[@CngDelta757]

@NorthwestDeltaa320 ironically that WAS the same seat (not the very same plane) from my last NWA 319 flight

[@CngDelta757]

@SkyWestCRJPilot Yeah, I usually know the PTU may run around 2:00

[@xjt10]

pure goodness omg!!!

[@CngDelta757]

@SkyWestCRJPilot well, the PTU was right under wher i was sitting

[@CessnaPilot1B9]

I love the PTU

[@MileHighAviation]

looks like the same view from your last vid of a319 MSP to MDW

[@hectorzambrano4092]

Well it's my favorite jet aircraft but WHAT WAS THAT SOUND AT 2:10? I hear it almost everytime I go on an Airbus aircraft.

[@elasarygutierrez2318]

Thats the PTU and it is used during the engine start and shut process it kind of cools the engine a bit.

[@hectorzambrano4092]

Ok, but it still sounds weird.

[@elasarygutierrez2318]

Thats because its bringing power to the engine.

[@hectorzambrano4092]

Yes yes I know, someone replied to me already. PTU sounds.

[@WillOHaver]

All of you are wrong, the PUT equalizes hydraulic pressure
