AirAsia 8501 Stall Warnings 'Screaming' Before Crash: Reports
NBC News ^ | 2015/01/21 | NBC News

Posted on 01/21/2015 11:06:32 AM PST by Gideon7

Warning alarms can be heard "screaming" on the cockpit voice recorder of AirAsia Flight 8501 before it crashed, an investigator was quoted as saying Wednesday.

Among the audible alerts is one that indicated the plane is stalling, the investigator told Agence France-Presse (AFP) and the Wall Street Journal. NBC News was immediately unable to confirm the accounts.

The reports come a day after Indonesia's transport minister said the Airbus A320, which crashed last month with 162 people on board, was climbing at an abnormally high rate before it plunged and disappeared from radar.

"The warning [alarms] kept on screaming, and in the background, they [the pilot and co-pilot] were trying to recover the plane," the unidentified investigator told the WSJ. "But what they said wasn't clear." He added that the flight data recorder also indicated that stall warnings were going off.

AFP reported the same claims, citing an investigator from Indonesia's National Transportation Safety Committee, adding that the pilots' voices were drowned out by the sound of the alarms.

Minister Ignasius Jonan told Parliament on Tuesday that radar data showed the doomed jet was climbing at about 6,000 feet a minute before it disappeared on December 28. "It is not normal to climb like that, it's very rare for commercial planes, which normally climb just 1,000 to 2,000 feet per minute," he said. "It can only be done by a fighter jet."

Me thinks this aircraft pitched up and back, then lost a wing or stabilizer making it impossible to recover at that point.

All you have to do is let go of the back pressure on the yoke, go full power and level the wings. Your really don’t need to push the nose down either. It is the first thing you learn how to do in a plane after learning how to make a turn. Stalling at 32,000 feet is not serious.

GPS can give you ground speed. Pretty close to airspeed if you know the current wind...

and your track. Up at 30000 feet, the winds can be well over 100 knots if in or near an upper level jet stream.

Would be REALLY confusing if an aircraft was GPS'ing that your going backwards!

Additionally, they will find a wing or stabilizer miles from the bulk of the wreckage, which would support my theory.

“With heavy jets, once a stall occurs, can there be a recovery?”

From the sounds of it, and is was true in the Air France flight, if the pilots had let go of everything it is quite like the aircraft would have flown itself out of the trouble it was in. Pretty much most modern airline aircraft are designed to recover from a stall ‘hand off’ as long as the CG is within limits.

Don’t fly with any Asian pilots. At best, they seem to be totally incompetent.

I recall a show about the investigation into the AA flight that crashed in Queens 2 months after 911.. They hit wake turbulence from a 747 that took off ahead of them. Trying to get out of it they cranked on the tail rudder, per training, and broke the whole tail off crashing the plane. Steep climb here indicates avoidance maneuver gone wrong on AirAsia.

Weather conditions were very bad. They weren’t permitted by ATC to go up to avoid the conditions because there was a plane above them, and then it looks like they decided to take their chance and power up after that plane was no longer a problem. They just miscalculated or perhaps didn’t know the extent to which they could push their own plane.

The other thing is that they actually were not supposed to be in that airspace at that time, because Air Asia was permitted to fly that route at that time only on certain days, and this wasn’t one of them. They’ve apparently had this flight for awhile, so obviously the port authority there was covering for them, but it wasn’t officially permitted so that meant that there wouldn’t have been any plan for them when things went bad.

Yes, it’s looking more and more like the 447 crash. The latter was really due to the faulty pitot-head design, and resulting icing and air-data failure, which made the TMR FCS fail, which turned it over to a back-up mode that wasn’t expected. Of course, Airbus couldn’t afford to take the aircraft system blame so the pilots were blamed. SOP in so many cases.

That crash was due to the co-pilot’s inexperience with flying the Airbus A300 without the computer.

...

True, but there was a lot more to it than that. The worst problem was there were three very poor pilots in the cockpit.

In AF447, the other pilot on the right was pushing the joystick forward, but the joystick on the left overrode him, and he didn’t realize it.

...

I thought the computer averaged the two sticks.

Anyway, making it clear as to who is flying the plane is piloting 101 for airline transport.

They were high enough (32,000 ft) to have plenty of time to recover from a stall.

...

True enough, but a passenger jet that size can lose altitude very rapidly. I think it only takes a couple of minutes.

The latter was really due to the faulty pitot-head design

...

The pitot tubes only stayed frozen for 60 seconds. Nobody on deck seemed to notice. Other crews have dealt with frozen pitot tubes safely.

Yeah, but “He be genius,” Hollywood’s owners say so.

I've traveled in that part of the world and one thing I can say is that thunderstorms of the most amazing intensity are an everyday occurrence there.I'm not an aviator but it's hard to imagine that flying through,or near,such storms can be conducive to the safe operation of even the most advanced aircraft.

So, basically, another Airbus just fell out of the sky.

Not a high flier but isn’t there pitot heat that can be turned on?

I’m no pilot...but if a jumbojet is spinning around like a beer can thrown out the window of a car, there may be no chance of recovery. All the controls an lift surfaces assume a forward direction.

Did the name of the pilot include “mohammed”?
