The aircraft’s structural resistance is protected for a landing at the Maximum structural Takeoff Weight (MTOW), with a rate of descent of -360 feet per minute.
Nevertheless, the minimum required air climb gradients, in the case of a go-around, must be complied with.
A fuel jettisoning system must be installed on each aeroplane to reduce aircraft weight unless it is shown that the aeroplane meets the climb requirements of Approach Climb gradient and Landing Climb gradient at maximum take-off weight, less the actual or computed weight of fuel necessary for a 15-minute flight comprised of a take-off, go-around, and landing at the airport of departure with the aeroplane configuration, speed, power, and thrust the same as that used in meeting the applicable take-off, approach, and landing climb performance requirements of JAR-25.”
When the Maximum Takeoff Weight (MTOW), less the weight of fuel necessary for a 15-minute flight (including takeoff, approach, and landing at the departure airport) is more than the maximum go-around weight, a fuel jettisoning system must be available.
