Maximum permissible takeoff weight (1 000 kg)..................................................................... 81.2
Associated speeds,
V1 = 146 kt + 1 × 15/10 = 147 kt
VR = 156 kt + 1 × 15/10 = 158 kt
V2 = 161 kt + 1 × 15/10 = 163 kt
• Check that the speeds are higher than minimum speeds from the chart and from VMU table.

COMBINING CORRECTIONS FROM FCOM AND CHART
Applicable to: ,
, MSN
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

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..................................................................... 88.1
Enter the 10 kt head wind column and interpolate for 25 °C, CONF 2,

Retain CONF 2 for takeoff configuration (Takeoff speeds are lower).
2. First, apply the correction (Refer to DSC-52-30 WARNINGS AND CAUTIONS).

Interpolate takeoff speeds for 84.8 (1 000 kg) in the 10 kt head wind column,
V1 = 154 kt , VR = 156 kt , V2 = 156 kt

V2 = 156 kt + 1 × 15/10 = 158 kt
Check that the speeds are higher than minimum speeds from the chart and from VMU table. (It
is reminded that if the speed checks are not fulfilled, the corrections must be recalculated using
