In the Airbus FCOM there are provided Charts for several climb gradients(in the other world called WAT limits)and the max'weights for 'Go-around"(Fcom 3.05.35)..Although one uses 2.1%gradient,for the G/around,one is required to miss with a 2.4&gradient after a CAT2...Generally reviewed on Line Indoc'-but missed by most.
