If both V SO and V S1g are available, the higher resulting V AT shall be used.\n(b) The aeroplane categories specified in the table below shall be used.\nTable 1: Aeroplane categories corresponding to V AT values\nAeroplane category\nV AT\nA\nLess than 91 kt\nB\nFrom 91 to 120 kt\nC\nFrom 121 to 140 kt\nD\nFrom 141 to 165 kt\nE\nFrom 166 to 210 kt\n(c) The landing configuration that is to be taken into consideration shall be specified in the operations manual.\n(d) The operator may apply a lower landing mass for determining the V AT if approved by the CAA.
