(a) The pilot procedures required by rule 137.103(a) consist of—
(1) finding the MCTOW in the aeroplane flight manual and the original aeroplane limit load factor; and
(2) locating the ‘original aeroplane limit load factor’ on the horizontal axis of figure 2, going vertically up to the reference line and then horizontally to the vertical axis to read the ‘maximum recommended percentage weight increase’; and
(3) increasing the original category MCTOW by this percentage to find the new maximum take-off weight.
(b) When considering whether to operate up to this new maximum takeoff weight, the pilot must take the following factors into account:
(1) the pressure altitude of the aerodrome;
(2) the ambient temperature at the aerodrome;
(3) the runway surface type and condition;
(4) the runway slope in the direction of take-off;
(5) the headwind or tailwind component in the direction of the takeoff;
(6) any other factors that may affect the performance of the operation.
