regulatory bodies got off their collective rears and fixed this problem once and for all ?
the problem lies only with the lack of will to do what is required .. the solution itself is simple ... either you weigh all load or use a statistically based schedule(s) of standard weights ..
the cause of the crash was: "significant overloading and / or CG out of range,
operator risk management problem .. just like it is at the moment
A weigh-bridge unit need only be built into the floor
would be feasible for gross weight summing and a swipe of the pax boarding pass would take care of CG
the display could even "flash" individual seat icons
not really much use as the variation per flight essentially is a normal distribution so a significant number of folk will be outside the mean value
all aircraft were deigned to maximise the number of seats
... as might follow from a desire to maximise revenue ?
How close to the "absolute limit"
each certification establishes a maximum number of occupants so that is the readily obtained limit
"standard pax weights" under the old rules are no longer representive
then redo the sums - QED
they also included a "standard mix" of adult males, adult females, and children.
can you provide any evidence to support this idea ?
