Supposedly the aircraft has some sort of system that can recognise gestures like that.

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.

I've flown in A32Xs before and noticed they make a bunch of weird noises. Boeing jets, on the other hand, tend to be quieter - some 'clunk's, but no barks or whoops or "WOOOORIUUUA" noises.

Is there some reason why Airbusses tend to be louder? Are the French big fans of odd barks and squeaks? Is it their passionate nature expressing itself through the medium of hydraulic noises?

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! :shrug:

Except the system in the X-47 cost $5 million per aircraft, took twelve years to develop and is still probably outperformed by Kinect.

RMPs are loud. 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...

Looks like there were a bunch of guys with remote-control rigs of some sort. 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.

At the end of the video theres a shot of the drone landing on land. I'm sure they'll work up gradually to landing on the carrier, it might even be hand flown down to a carrier.

They did a land landing after the launch. They have done arrested landings on land though. Probably a few more weeks before a full carrier launch/recovery.

I don't think that they did. Pretty sure that it was just loaded onto the carrier. The first landing on a carrier would have been bigger news than the launch.

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:

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?

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.

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. :v:

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 what you do on a 707. Instead of slides, the overwing hatches are packed with the big survival rafts.

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.

My brother is driving through South Dakota, apparently "a fighter jet" buzzed him in I-90. I love to think the pilot was just messing with him.
