CAP698 – Maximum TOM

a) Enter with Field Length Available (TORA). Move vertically to the runway slope reference line.

b) Parallel the grid lines to the appropriate runway slope then continue vertically to the wind component reference line.

c) Parallel the grid lines to the appropriate wind component then continue vertically to the flap reference line.

d) If flap is 15°, parallel grid lines then, with a pencil, draw a vertical line through the weight grid. If flap is 5°, with a pencil, draw a vertical line from the reference line through the mass grid.

e) Enter at the aerodrome ambient temperature and proceed vertically to the aerodrome pressure altitude.

f) Proceed horizontally right to the mass grid reference line.

g) From this point interpolate and follow the grid lines to intersect the vertical line drawn in d) above.

h) From this intersection draw a horizontal line to read the Field Length Limited TOM

i) Apply any corrections necessary.

Field Length Limited TOM = 56 000 kg. Having a look at the graph, you can easily understand that 15° flaps will give a higher TOM.

032.05.01.01.01: Determine from given graphs the field-lenght-limited take-off mass (FLLTOM) and describe situations in which this limitation could be most restrictive for take-off.
