ChickenOfTomorrow posted:Stupid Airbus question: During taxi in an A320, I heard 4 or 5 "bark"-like squeals from the undercarriage. Upon reaching the gate, I heard something similar. Since the barks seemed to coincide with engine spool-up/down, I suspect the PTU. It sounded like it was right under my feet, and freaked the heck out of a bunch of people around me. The barking is a hydraulic converter, letting the #1 system power the #2 system when the #2 engine is shut down. It's kind of a fun noise, really. I think the Boeings use all auxiliary hydraulics for taxi, powered by the APU, so no barking of hydraulic transfer, but I'm not sure about that.

I flew the other day on an A319, my first time on an Airbus after flying dozens of times on Boeing planes. And I've heard the noises I think you're talking about. There we're some loud bangs every time they applied the brakes. Freaks me out but then I read about the A319 and its never had a fatal accident which makes me feel much better for my flight tomorrow on one.

Yup, the barking dog is the PTU. 767s have one as well, but it works slightly differently so you don't generally hear it. Plus, bigger plane = noisy bits farther from cabin. So on the baby bus, whenever either the green or yellow hydraulics pressure drops and there's a demand on that system (1 engine running, or running on electric pumps and a high demand user causes pressure to drop), the PTU kicks in and uses the other hydraulic system to spin a pump to boost pressure in the low side. There is no fluid transfer between systems. As for the clunky brakes, they're just clunky!

You should hear the ones on a DC-10 when one of the two relevant systems runs dry and the FE forgets to turn it off...

I'd be a little surprised if they had the technology/confidence in technology to trust waving your arms at a back-up camera, when they can put two contractors with redundant remote controls onboard for time and a half. Military tech test/demos are fake as hell, and this is probably at least as faked as the fill things that aren't supposed to explode with water and things that are with radio transmitters tests.

I know this is a stupid question, but did the drone land on the aircraft carrier after? I remember a saw a post earlier of a test with an arresting hook that proved it could be done.

I'm sure they'll work up gradually to landing on the carrier, it might even be hand flown down to a carrier.

The first landing on a carrier would have been bigger news than the launch.

The end of the video says they're gonna do a bunch of approaches and then by the end of summer do a full carrier landing.

That drone looks so weird on the flight deck, even stranger in the hanger bay. One of my favorite things to do while waiting in the chow line was to check out the planes. Hard to day dream about one you can't pilot on the inside.

A Boeing 737 caught fire upon landing at Moscow's Vnukovo Airport today: https://www.youtube.com/watch?v=eUjvc8uOfhQ That emergency exit onto the wing seems a little odd - how are they meant to get off the wing onto the ground, and aren't they a little close to the fire exiting there?

# ? May 18, 2013 17:18 |

I don't think the wings are that high off the ground. And using the exits intelligently to avoid the fire is part of any aircraft evacuation, regardless of where the fire is.

JingleBells posted:A Boeing 737 caught fire upon landing at Moscow's Vnukovo Airport today: Overwing exits normally have slides that inflate when you open the hatch. I do not know why that didn't happen, here. Maybe we have a 737 mechanic or driver around? As a general rule though, you should probably not stand on top of the fuel tank during a fire evacuation.

I thought sliding down the flaps was normal for a 737 evacuation, but I could be wrong. Just recalling the emergency cards from the seatback pockets from memory.

This is correct; there are no evac slides for the overwing exits in a 737. IIRC survival rafts are optional for the overwing exits as well.

Out in SF today, saw a helo fly under the Golden Gate. I didn't realize until I got home and looked it up that the FAR that prohibits fixed wing aircraft from doing that doesn't apply to rotorcraft, so that's cool I guess.

The US Airways Dash 8 I was talking about a few weeks ago, the one that double diverted back to Roanoke, yeah well it crashed (belly landing) in Newark this morning with a landing gear failure... Why are they posing by the registration? Is it just to make sure I knew it was the same aircraft?
