Real deviation
SaturnV
"wallybird7, you are suggesting that they deliberately flew into a defined thunderstorm? Defined by who? and when?"
What I am saying is that they did not deviate far enough away from the line of thunderstorms.
No one knows for sure the dynamics of any particular thunderstorm except that they can contain severe turulence and up and down drafts and most likely had something to do with loss of pitots and possibly control.
A deviation around the line might add 15 minutes of time and fuel, and if so, my opinion is we wouldn't even be discussing AF447.
