Just to keep it together as this is what I'm referring to when I'm asking about the hydraulic system. I'm not referring to the brakes. I am attempting to figure out why it appears the control panel completely died and couldn't be navigated even remotely from ground, why the plane attempted to drop, fly, then spiral. Do the p
ilots lose all control over manual steering when the
hydraulic systems are all failed in the A320?

This post did not start out ending up like this long! In sluething about found a couple of other reports! And I had trouble trying to say what I was trying to say!!
Total loss of hydroaulics is very serious! But most aircraft have redundent systems. But (below) I do not think that happened intially in this crash. If what follows is accurate, moo :
I think the media has given many the image that plane went out of control instantly. I do not think that is what happened - since ACARS released. In decompression must get down to 10000 feet and fast (hypxia) - passengers. The cockpit crew instantly put on their masks and go down. It seems as if that segment was controlled- under pilot command. Everything got narley around 9000 feet. Structural overload?
That is also hopeful as far as the recorders go. There is an increased liklihood that they recorded at the same time as the ACARS were transmitting. And we know from ACARS that was a beginning to the accident sequence. Would be great - cause from the dialog in the cockpit we would know what the flight crew were battling,(firebomb and/ or sudden decompression) and how the aircraft was responding to what they were trying to make her do.
The sad part of this is that (as opposed to instant sturctural failure) might increase the reality - that at least for the intial descent, (controlled) that passengers might have been more aware of what was happening.
Whatever version is accurate, the media playing it like the plane did a 360 degree turn is a physical impossiblity. Swept back wing aircraft do not have the ability to do a 360! They must have forward motion or they stall- peroid.
That was the beginning of, in most liklihood, a stall, (visualize a plane slowly quitting moving forward in the air, at a certain threshold there is not enough air going over and under the wings, to hold it up in the air and it stalls falling out of the sky) When they stall , most of the time they sprial down (circular/roll). I think that is what they are describing as a 360 - its the beginning of a spiral stall.
On this one tho there had to be something else to start everything. If it was only a stall, at that height they would have been able to recover. Nose down get speed, lift nose up and your on your way!
Just found this out 5 minutes ago topic switch . Remember the AIr Asia one we followed , well final report out . Amazingly it was really close to AF. Causation different, but....
Air France was interesting in that she actually went down like a belly flop into the ocean.
In some ways that is better in terms of debris recovery, smaller debris feild - intact machine slamming into ocean. It still took them (and France is on par with NTSB) two years to get the recorders.
In AF, (and apparently a bit like AA) the pilots thought they were "speeding" when the plane was actually losing speed. If your going to fast and you lift nose up - slows it down. If your going to slow you put the nose down.Get speed back. They were putting in nose up inputs. . But lifting up the nose on a plane ready to stall cause it to slow makes everything awful - . There is a point of no return doing what they were doing. . Must have forward speed to keep the wings "holding " (lift) the plane up in the air.
It was their fault, but not really. Their speedometer got clogged with ice and was giving them wrong speeds - which also made the auto pilot do strange stuff. The AIr Aisa guys were doing a similair thing, the only difference being the intial cause of the problem was rudder related in AA.
Version 84:
New story now,:
The head of Egypt's state-run provider of air navigation services says that EgyptAir flight 804 did not swerve or lose altitude before it disappeared off radar, challenging an earlier account by Greece's defence minister.
Ehab Azmy, head of the National Air Navigation Services Company, told The Associated Press news agency on Monday that in the minutes before the plane disappeared it was flying at its normal altitude of 37,000 feet, according to the radar reading.
"That fact degrades what the Greeks are saying about aircraft suddenly losing altitude before it vanished from radar." According to Greece's defence minister Panos Kammenos, the plane swerved and dropped to 10,000 feet before it fell off radar.

That IS what that radar 24 site was showing (37 000 and poof) , the night it broke. Who knows huh!
BUT----- That makes sense. 10,000 is where they try to get to in decompression. Which makes this notion that it exploded at cruise silly. Blown up planes dont "know" you better get down to 10000!! Pilots, on the other hand do!!
" In the cockpit, the flight crew will don their rubber masks and begin a rapid descent to a safe altitude anything below 10,000ft." per

I just heard a radio report in my car, and the KFI reporter said that one of the pilots appeared to have been radicalized? Anyone else hear a report like that anywh
