This is done by holding the aeroplane on the ground until it reaches an increased VR and climbing at an increased V2. d) Continue horizontally right to the reference line of the right-hand graph. Check VMBE. From this point interpolate and follow the grid lines to reach a vertical input in the right-hand graph of the normal climb limit mass. and there is a large excess of available field length over that which is required. h) Add the mass increase to the normal climb mass limit. c) From this intersection move horizontally left to the vertical axis to read the climb mass improvement and horizontally right to the vertical axis to read the increase to apply to V1.16) except that the initial entry point is the tyre limit mass minus the climb limit mass. July 2006 Section 4 . f) Repeat this process in the improved climb performance tyre speed limit graph (Figure 4. b) Enter the relevant left-hand graph with the value of the field length limit mass minus the climb limit mass. which equates to Vx (the speed that will attain the maximum climb gradient). then it is possible to improve the take-off weight and still attain the minimum climb gradient requirement (subject to the limitations of the tyre speed and field length limitations).
