The news says that A320s are designed so that they cannot dump fuel,
thus this loaded plane must fly around for a while to burn off some.
Anyone know why the A320 is designed that way?

(a) A fuel jettisoning system must be installed on each airplane unless it
is shown that the airplane meets the climb requirements of §§25.119 and
25.121(d) at maximum takeoff weight, less the actual or computed weight of
fuel necessary for a 15-minute flight comprised of a takeoff, go-around,
and landing at the airport of departure with the airplane configuration,
speed, power, and thrust the same as that used in meeting the applicable
takeoff, approach, and landing climb performance requirements of this part.
