What is flex?
Questions from a light aircraft chap to any heavy jet chap.
Interesting discussion recently regarding the Emirates emergency landing at Jo'burg and a term kept on popping up.
What is flex as applied to heavy jet considerations?
Is it literally flexing of the fuselage or wings, or is it a theoretical concept applied as an additional factor to maintain safe operation?
What are the consequences of mis-calculation?
Answers on a postcard (if you are so inclined) to the usual address please.
Thanks very much
