• Start by reading the note at the bottom of the document. We are required to reduce the field length by 650 ft for anti-skid operative: 6155 ft – 650 ft = 5505 ft.

(1) Enter at a field length available of 5 505 ft at the bottom of the graph. Continue vertically upwards until you intersect the WIND REF LINE. Adjust for a headwind of 20 kts, diagonally up and to the right.
(2) Continue vertically upwards until you intersect the FLAPS REF LINE (we can disregard the runway condition because the runway is dry). From the REF LINE diagonally up and to the left until the top (15° flaps), then vertically up again until you intersect the 3 000 ft line.
(3) From this position horizontally to the right to read a result of 51 000 kg.
