What's up with Malaysian air lines
I will never take Malaysian planes!
They are not bankrupt yet?
Poor Malaysians,
2014 is worst year for air traffic in my life i have seen till now.
Whats going on Malaysia?
airline from Malaysia.
Whats with Malaysia
Malaysia is going through a dark period in aviation
Malaysia is sure a bad place to fly
what the hell is going on with malaysian civil aviation ?!?!?!
There is massive cloud in Jakarta Today.
Bad weather over that region.
They need to make planes being able to survive ocean crashes.
It shouldnt be too hard.
Air Asia management in the earlier hours refused to admit that his plan was missing that causes late rescue operation
in my opinion it should be reviewed whether it is a criminal act or not.
it falls freely without any control, side ways, upside down, spinning.
Some times hydraulics fail completely.
If the weather was bad, the jet streams could have caused the plane to dip or stall uncontrolled, but seeing at the cruise speed, which was almost 900 kms per hour. I doubt if it was jet stream.
especially Malaysia
Actually you're wrong. Most stalls in civil aircraft are relatively benign and easily recoverable.
For example, when the Air France A330 (AF447) stalled, the pilots still had lateral (and pitch) control.
Stalls and hydraulic failures are independent.
Every stall report I've read, whether it be Air France 447, Bergenair 757 or just a Cessna 152, hydraulics are working.
Too simplistic to look at stall in terms of airspeed and (to put it bluntly), it is incorrect to do so.
Read up on angle of attack.
Especially Indonesia.
This was a PK registered aircraft which means it was flying on the Indonesian aircraft register and under Indonesian regulatory oversight.
it is its momentum against which the controls fail to work. In some cases, yes they work.
If the plane stalls , (Deep stall) nose up, that is what I am taking about. It becomes unrecoverable.
Again momentum has nothing to do with it.
I was at the joint Boeing Airbus stall lecture last year given at the Royal Aero Society in London. The video of which, minus the airbus and boeing test stall footage, is available on youtube.
I asked Terry Lutz (Airbus test pilot, former USAF T-38 and F-16 test pilot) about the stall characteristics of airbus airliners with the context around the A330 stall with Air France.
As you may know, the aircraft stalled at approximately 38000ft and after a rate of descent exceeding 10000foot/minute, it belly flopped into the South Atlantic.
Now, throughout the free fall, the aircraft was traveling with a forward speed in excess of 100 knots and even in a stalled state, it responded to control inputs.
According to Airbus test pilots I've spoken to, the aircraft would have had enough dynamic pressure (q) to effect a recovery from about 25000ft.
We're talking civil airliners here with conventional wings and conventional tails, not delta winged jet fighters which often exhibit the stall characteristics you're referring to or the old T tail designs which are rare in commercial airliners.
Dynamic Pressure
But that stall was recoverable if they had the correct reading.
well, had they were aware of the accurate speed or some sense of stalling they could have reacted. Multiple warnings on air speed and stall, when instruments are showing wrong data, confuses the pilot.Like I said, speed is meaningless in a stall. Angle of attack is what the wings "see" and is all they care about.
Having the Indicated Air Speed would not have helped them.
The stall recovery procedures for Airbus and Boeing aircraft make no mention of speed during stall recovery because it isn't relevant.
The procedures emphasise pitching nose down to reduce the angle of attack first.

What's up with Malaysian air lines, hope everyone is safe.
You can't be very old then.
There have been hundreds of pitot icing events like that on AF447. No aircraft manufacturer is immune to them. That is why the aircraft OEMs have unreliable airspeed procedures which will ensure the aircraft will continue flying.
AF447 didn't follow the procedure.
The rest is history.
if you fly through storm and you do not have proper altitude
How would a pilot know when is the pitot frozen and when not?
In the next minute it's back online and the other again frozen. That is tough.
