The Real Problem

It seems to me lately that what everyone on this site seems to forget or ignore is what got this flight into the mess in the first place. They went dead on into a thunderstorm. And shortly after,...

No one is saying Boeing vs AirBus. Or pilot qualifications.

Understanding Angle of Attack.

PJ

I too am an old retired Boeing and Airbus pilot. My take is that AoA is important when dealing with very slow flight, i.e. when a Navy pilot has to bring it in on a very short deck with...

Avoid cb's

I’d like to throw in my 2 cents of input.

We have a triply redundant system of pitot tubes which all failed at the same time. Of course using the very same systems.

Which provide info to the...

Stall speed

Hi Sensor

As we all now know from earlier posts, no such thing as "stall speed" its all about AoA.

In all my years in aviation there were no AoA indicators flying mostly all the A/C made in...

ZOOM CLIMB What really happened

Hi Henra

All Valid questions.

“Uncommanded 7000 fpm rate of climb”. Why I think that it was uncommanded.

When a plane is at max cruising altitude (35,000) which the crew noted because...

Restricted control

AlpaZulu

Auto Trim is not a primary flight...

DEVIATE

GarageYears

Yes a slight misrepresentation -- and yes I know CB's are common. But every other flight deviated. Perhaps 447 did not deviate enough. But with all the glitches to me crystal clear...

uncommanded climb

GarageYears

Zoom climb

Nobody knows what is going to happen when an a/c enters a thunderstorm. No one.

If a strong enough updraft occurs it could push the plane up at 7000 fpm at the same time sending the nose down...

1. Why did the pitots ice up?
2. Why did the A/P and A/T disconnect?
3. Why the zoom climb without clearance from ATC?
4. Why the sudden reduction of speed at top of climb?
5. Why when at...
