@michaelbobe1 Im not sure the frame number, but the structure with the 2 holes in is called the keel beam. As you look at the PTU your looking rearwards. Behind the vertical structure is the rear cargo bay! If your not sure ill do some more filming!
It will make this sound with either the apu running or ground power plugged in. The APU only produces power and air. You wont hear this inflight because the engines are powering the yellow and green systems, blue system is powered by an electric pump or by hydraulic pressure from the ram air turbine!
Ya mon.....It's no biggie to say where ya work on the Bus. Is it? Hell, I'm across the pond.....Almost a direct line west from you. Lookin' to get a different job though. The airline that I've been with for years is a total shit since the new managment took over. They have cut our pay and bennies. Slashed our paid vacation down to nothin'. And they lie through their teeth about EVERYTHING. I shoulda gone to med school like momma told me to.
Company i work for is ok i guess, but at this moment in time i think its best to stick with who you are with. Think next year a few more airlines are gonna go down. So are you A and P?
Yupper. You guys don't have the same distinction over there? Or do ya? I remember being told that the Canadians and the Brits/Europeans work on 'specialties' rather than the whole acft every night. Is that true?
We have a European licensing system here now, your either B1 or B2. B2 guys are avionic and can sign for stuff that requires specialist test equipment, B1 guys cant. B1 like myself can sign for anything on airframe and engines plus we now have an avionic extension, but cant sign for using specialist avionic test equipment. B1 is the way to go.
You don't like working avionics? You'ld rather be out in the elements ALL the time ck'in APU oil or opening cowl doors, servicing hyd.s, changing logo lights, ect? I like the fact that I've been sent to avionics T/S schools AND IAE/PW eng borescope, eng T/S schools ect. It gives me a very wide view of the acft I work. Plus you can intergrate relationships of say an LGCIU into the various systems that correlate to it. SEC/ELAC understanding is good but if you can't match them to where they 'mesh'
.....then you are not living up to your personal potential. Say you have a WTB prob on a Bus and it has to be worked from the inside as well as the outside...Do you have two separate A&Ps working it? I understand their reasoning for separating you into classifications but it just seems like a waste of 'brain power'. You seem like a smart guy, why then so satisfied to stay on the outside?
I realize fixing interior items and lavs/coffee maker R&Rs/CIDS problems aren't exciting but at least it breaks things up from ALWAYS knowing you're gonna have wheels, brakes and oils EVERY night....Sorry, just my big American mouth flappin' away there. Please don't take it the wrong way man. We both basically do the same thing for a living. And I DON'T mean to diminish what you do as opposed to what I do.
it means the aircraft is on 'final' which is the last leg of the approach - (basically the aircraft is lined up with the runway and wont make anymore major turns until it lands)
The question was in referance to the 'context' in which he was reffering to "finals into AMS". I know what the term is as it relates to an acfts' flight towards its' next runway......But thanx just the same mate.
I think it's actually the PTU making the 'barking' sound resulting from the hyd fluid being forced through it. Remember at the end he's in the rt whl well serv area? Watch the accum pres gage. It coincides w/the 'bark' when it drops and then regains 3000psig. But the actuall SOUND I'm thinkin' it is from the PTU. Leave yellow on and turn off the PTU. Ya might not hear it. What do you think Bob?
I hope that cleared it up for ya man (I answered ya up top). I'm sure Sterling could have answered that as well, maybe he thought you were talkin' about the bark too. The blue pump sounds the same.
If you turn off the PTU you would only hear the yellow pump. The PTU only comes into operation when there is a difference of 500psi or more between sytems.
Oh, ok, sorry. The high pitched noise is the pump. Ya see the guy who is takin' this vid (I guess on a cell phone) is standing just aft of the yellow pump.
if i hear this during a flight im going to freak out ! :S

Boeings have complex hydrolics as well but they do not bark like the A320! Boeing all the way!!!!!!!!!

Have u ever looked in the gear bay on a 737?

Probably because your simple brain would never understand the complexities of an aircraft hydraulic system

Well I do. But you obviusly don't know how to use electronic devices on a plane. Your simple brain.

Hey man, what's "Finals into AMS" mean? Like goin' into Amsterdam? Don't you work on Busses in Southern England somewhere?

What's that really high-pitched noise? an external air supply?
atav 3 years ago
That would be the yellow system electric pump!
Sterlingjob 3 years ago
Really? So when the Yellow Hyd. elec. pump is being powered by say: the APU it makes this sound?? Can you explain please? :) thanks sir

Yea man, I kinda fig'd that was it but I rarely turn off the PTU and then go down to listen to the differance.
