COMBINING CORRECTIONS FROM FCOM AND CHART
Applicable to:
Proceed as follows :
1. Enter the chart with selected configuration, OAT and wind to read the maximum takeoff weight.
2. Apply corrections from FCOM to determine an intermediate weight. Interpolate associated speeds
for intermediate weight in the same column (same wind and configuration).
3. Apply corrections from RTOW chart as explained above.
EXAMPLE 3
DATA :: OAT = 25 °C
Head wind = 10 kt
Air conditioning ON
QNH = 1 028 hPa
WET runway
1. Use the chart (Refer to DSC-45-25 GENERAL).
Enter the 10 kt head wind column and interpolate for 25 °C, CONF 1+F,
Max TO weight (1 000 kg) air conditioning OFF..................................................................... 71.2
Enter the 10 kt head wind column and interpolate for 25 °C, CONF 2,
Max TO weight (1 000 kg) air conditioning OFF..................................................................... 70.8
Retain CONF 1+F for takeoff configuration.
2. First, apply the correction (Refer to DSC-52-30 WARNINGS AND CAUTIONS).
Max TO weight (1 000 kg) air conditioning OFF..................................................................... 71.2
Air conditioning correction.......................................................................................................- 2.2
Intermediate weight..................................................................................................................69.0
Interpolate takeoff speeds for 69.0 (1 000 kg) in the 10 kt head wind column,
V1 = 151 kt , VR = 151 kt , V2 = 153 kt
3. Apply WET correction

Associated speeds,
V1 = 151 kt - 4 = 147 kt
VR = 151 kt - 1 = 150 kt
V2 = 153 kt - 1 = 152 kt
Check that the speeds are higher than minimum speeds from the chart and from VMU table
