US Airways flight #5 hydraulic failure part 2 - Phoenix to emergency landing Kansas City

[xhemexx]

So did you guys make it out ok

[starblazr]

0:37 "Why are we using a backup?" Well, it's so you didn't crash and die. But, alas, you lived, so you better thank your lucky stars that you were hearing that pump. Yes, it was at 30k feet. Something broke mid-flight, just like a car does going down a highway. it happens, sometimes unexpectedly... that's why they designed it with that little whiny pump to make sure that when something breaks, they can land.

Nothing to see here -- moving on....

dear dazed767 normal during push back /start up .... this was 30k in the air. Please somebody explain that this was going on for over 2 hours in the air. If this is normal, Im done flying

[Dazed767]

Given very little explanation? He told you the problem, what more do you want? Search Airbus PTU on youtube, it's usually normal during push back/startup.

[cozycampfire]

Oh we were diverted. And fire trucks were waiting for us. We also had heavy hydrualic fluid smell.

I was flying an AIrbus 340 on Microsoft Flight Sim as well as your plane Airbus 320/319 and had the same hydraulic failure. Now this was over the Atlantic on the 340 and I switched to backup no problems. You were safe and in good hands. I would not let this stop you from flying US Airways. If it was a clear lfie and death situation you would have diverted right away or get sent back to Phoenix.

Obviously the crew didn't paint an accurate picture in the mind of the passenger filming this video. Dave46563 is correct. This is the sound of a hydraulic power transfer unit supplying pressure to a failed circuit. The failed device is NOT the device making noise. The sound is coming from a transfer unit, and it is a very good thing. This is music to my ears, ensuring me that all flight control surfaces outside the aircraft are ready to respond to any command from the pilot flying. I love it.

[dave46563]

You can hear the PTU which transfers hydraulic power from one system to another in the event of a failure. it would not "shear off". modern airliners are built with plenty of contingencies and back ups. what you were hearing was actually a good thing. i'm assuming the autopilot was engaged during this part of the flight and the computers send commands to the hydraulics to move the flying controls. the PTU whirrs up to provide the hydraulic fluid. yes it's an annoying sound. it cant be helped

[rickram1961]

USAIRWAYS is definitely my favorite airline!

[AA6RH]

The noise was annoying. Flight safety not compromised. Forgive pilot for not delivering high level technical dissertation on hydraulic systems. 

[fastst1]

Backup pumps come on as procedure whenever there is any problem with the primary. If there aren't any control surface changes, the pump will whine to a stop, with any control input, the pump spins up and supplies fluid, stopping when its not needed.

[allflight57]

airline passengers are so stupid haha

[iflyc77]

Stop talking about shit that you know nothing about! This was not a big deal, or dangerous at all. Just annoying and expensive to fix

[sledxkeys]

Amazing how you are saying not to trust US Airways based on the backup hydraulic system of which you have no knowledge of whatsoever.

[av8or426]

Holy crap! Its gonna shear off, whatever it is!!!! ABORT ABORT!

[freeze3192]

ignant

Next time make sure to take brother Sam's parachute LOL

[cozycampfire]

The pilot said this was the backup pump. We had no steering and we had to make an emergency landing. There were 3 people around us that said they fly all the time for many years and have never heard that sound. We were given very little explanation.

[Element94]

@cozycampfire You probably had to burn off enough fuel to get to the maximum landing weight for the airplane (that's why you were in the air for 2.5 hrs). Nosewheel steering (for taxiing) is run by the primary hydraulic systems. However, the backup system allows for flight control movement down to a safe landing.

It's easy to complain when the outcome was favorable. Despite your misgivings at the lack of communication, the asinine policies you're complaining about saved your life.

[N605JB]

@cozycampfire They must have never flown on an airbus before, that noise is similar to the one if not the same as the ones you hear as the plane is starting up. This happened exact same thing happened to my plane as we were about to cross the Atlantic and we were given the same information you were. Everybody was calm and didn't overreact like you were doing. We landed perfectly safely and flew out on the exact same plane the next morning.

[maxhovid]

There are three hydraulic systems on that plane, you can lose any two and still fly safely. The noise that you've heard under the floor is the hydraulic transfer pump that pressurizes the other systems, in case one of the pumps fail. It takes a lot of testing and certification before an airplane gets to carry passengers, and a lot of people done hard work to make sure you're safe.
