What does this mean as it doesnt translate here in the UK?

This refers to the flight performance data (primarily, weight and balance)
that the flight crew needs to enter into the flight management system. The
crew usually has that before they push back from the gate, but occasionally
the airline doesn't get it to them until later. They can't take off without
it, because they can't verify that the aircraft is within its center of
gravity range or that the accelerate-stop distance is shorter than the
available runway length.
