CAL 777 hits CAT?

[sat74]

Overheard some CAL guys talking about one of their 777's from EWR over the pole that hit clear air turbulence and went inverted! Anyone know anything about this?

That was one big kitty to flip a 777 inverted.

I really doubt that any B777 would go inverted regardless of the CAT. The control laws that are a part of the FBW system on the triple 777 try to roll wings level before the bank angle gets to around 40 degrees. While anything is possible, this scenario doesn't pass the smell test.

I heard it wasn't really turbulence, but a lateral imbalance from the overweight 777 Captain getting back in his seat after his break. The plane was trimmed up for the IRO, not the CA.

Sounds more likely than the CAT turbelence explanaition when you really think about it. LOL

Over the pole, inverted? Did Goose flip of the Russians?

Sit down and shut up, jack@ass.

Just imagine what that turbulence would have done to the little piece of sh!t RJ PukeU flies!

Not defending Poc but looks like the RJ was good enough for you? Absent your RJ time you probably would not have been very competitive for CAL.

Yeah - happens all the time. Is that before or after they finished the USA Today?

Here's a clue for when you post in the future. Make sense and have a point. K?. LOL

I think there was just some confusion on the flight deck as they crossed the pole. One second they were happily going north the very next instant southbound. 180* turn in a flash.

In-flight upset

FWIW:

15 MAR 2007 ATSB releases final report into Boeing 777 in-flight upset event
In August 2005, Malaysian Airlines Boeing 777-2H6ER 9M-MRG suffered an in-flight upset en route from Perth to Kuala Lumpur. A safe landing was made back in Perth. The Australian ATSB concluded that a contributing safety factor was that an anomaly existed in the component software hierarchy that allowed inputs from a known faulty accelerometer to be processed by the air data inertial reference unit (ADIRU) and used by the primary flight computer, autopilot and other aircraft systems. Other safety factors identified were: 1) The software anomaly was not detected in the original testing and certification of the ADIRU; and 2) The aircraft documentation did not provide the flight crew with specific information and action items to assess and respond to the aircraft upset event.
