NTSB Briefing, NTSB claiming .3 to .8 g wake encounter caused crash?!?!?!

This is Bull $h!t!!!

The NTSB is LYING like rugs!!!

NTSB dude just claimed that .3 to .8 g's encountered during the wake encounter caused the Airbus to break up in flight...

Even a male reported asked "is this even possible".

"Isn't this normal bumping encountered when flying?"

Even the media don't believe them!!!!!

[Darth Reagan]

Perhaps .8Gs at a direct, perpendicular angle to the tail is rare, I don't know. I'm not questioning based upon some gut assumption. Let's hear from the engineers. If the NTSB is nuts, some pointy-heads at universities will surely tell us.

The man said it was from the FDR, but the lady said the FDR quit recording some 20 seconds before the CVR quit when the plane crashed...

You were discussing this crash with some others who seemed pretty knowledgeable about aircraft on another thread today. Can you ping them? I don't know the names.

[LTCJ]

I'm an AE. Did the briefing say it was lateral g's? Even then, why didn't they pin it down closer than .3-.8 g's?

[calvin sun]

Could the .3 - .8 g force, TOGETHER WITH a loose tail, have caused the crash. I agree (from reading other comments) that this amount of force is too little to affect a "good" plane. But could it be enough to force off a loose tail, causing other bad things?

My father, retired USAF, says pulling 7 g's in a fighter aircraft is quite common. He says they are rated for 9+ g's.

If the turbulence happens to impart a harmonic vibration, anything is possible.

Structural engineers have become the whores of the bankers and lawyers. Airplanes, bridges, cars, BUILDINGS, have all been designed to the absolute minimum legal (liability) limits. They pass the tests, but when they fail, they fail all the way. No redundancies or safetey margins to fall back on when they realize they forgot about something.

I wonder how the FDR would actually record this phenonemon - anybody know?

[Stevieboy]

Keep in mind folks that the Chair did say this was only an update - and that they'd have more later this evening after all of her people filed their reports.

Maybe they're just feeling us out.

[history_matters]

It is a clever story when you think of it - basically saying no one is to blame.

But for some clean up in Afghanistan, we can all have a nice quiet RAMADAN

They were saying it was a lateral force, but he also said the plane experienced another acceleration at the same time, I think vertical was what he said.

[samuel_adams_us]

It sure would be nice if they would spend more time figuring out how to fix the problem than figuring out how to lie to us. I am tired of all this government idiocy.

It's a N.T.S.B. cover up. They are trying to keep alive the american airline industry. Nope, no bomb here. Nothing to see move along. Keep flying even though we aren't keeping planes from blowing up. ( see flight 800 and this one too). Do you believe the gubmnt.? Are they telling the truth? Oh yeah, sure.

[justlurking]

Wouldn't you think turning the plane at 450mph would be about the same amount of force on the tail section if not more?

Depends on how the turn is made. A properly coordinated turn requires very little continuous rudder force, because what you are actually doing is changing the lift vector through the center of the plane to the left or the right.

Think of a plane dangling on a string, with it attached at the center of gravity so that the wings and fuselage are level. If you tilt that string to the left or right (by banking the wings) while keeping the string perpendicular to the wings/fuselage and pulling on the string to maintain altitude, the plane turns left or right.

Maybe someone can explain it better in words. It's hard for me to do without pictures.

Aircraft certified in the 'Normal' category are certified to +3.8g, -1.52g limits. This is nuts.

[samuel_adams_us]

I just sent an email to 60 minutes asking them to look into these statements. I think the magic bullet with JFK had more credibility.

[Blueflag]

did. thanks!

[samuel_adams_us]

You did a great job. I forgot about the lean. What is it, pitch, yaw, and attitude?
