commonly used corrections are wet runway, QNH, air conditioning and/or anti ice. A maximum of
three corrections can be produced on one chart.
To apply the corrections, proceed as follows :
1. Enter the chart with given OAT and wind to determine the maximum takeoff weight before
correction.
2. Apply the first correction :
If􀀃OAT􀀃is􀀃less􀀃than􀀃or􀀃equal􀀃to􀀃TVMC􀀃(line􀀃3),􀀃apply􀀃▹W􀀃correction􀀃from􀀃line􀀃1􀀃and􀀃▹V1/▹VR/▹V2􀀃

from line 4.
3. To combine a second (and third, as applicable) correction :
If􀀃OAT􀀃is􀀃less􀀃than􀀃or􀀃equal􀀃to􀀃TVMC􀀃(line􀀃3),􀀃apply􀀃▹W􀀃correction􀀃from􀀃line􀀃1􀀃and􀀃▹V1/▹VR/▹V2􀀃

chart and that V2 is higher than the VMU limited speed (Refer to PER-TOF-TOD-25-20

Note: QNH correction is given for ± 10 hPa. It is allowed to extrapolate ‐ linearly for greater QNH
deviation.
‐ When using a takeoff chart with failure cases, it is not allowed to combine two failure
cases.
‐ Corrections from the chart must be applied from top to bottom, i.e. in the RTOW (Refer to
PER-TOF-TOC-10-30 CHART LAYOUT), apply the wet correction first.
‐ If asterisk or dotted lines appear in the correction boxes, refer to more conservative
corrections provided in the FCOM.
‐ No speed check is required for the first correction. However, if the first influence
correction follows a conservative FCOM correction, a speed check is required.

Head Wind = 10 kt
QNH = 1 028 hPa
WET runway
Use the chart : Refer to PER-TOF-TOC-10-30 CHART LAYOUT.
• Enter the 10 kt head wind column and interpolate for 25 °C, CONF 1+F,

• Enter the 10 kt head wind column and interpolate for 25 °C, CONF 2,
max TO weight (1 000 kg).....................................................................................................258.9
• Retain CONF 2 for takeoff.
• Read associated speeds as V1 = 140 kt, VR = 149 kt, V2 = 156 kt
• ApplyWET correction
