EXAMPLE C
Applicable to:
DATA : OAT = 25 °C
Head Wind = 10 kt
Air conditioning ON
QNH = 998 hPa
WET runway
1. Use the chart Refer to PER-TOF-TOC-16-30 RTOW EXAMPLE.
Enter the 10 kt head wind column CONF 1+F, to read for 25 °C
Max TO weight (1 000 kg) air conditioning OFF = 76.2 + 0.4 × 2 + 0.04 × 11 = 77.4
Enter the 10 kt head wind column CONF 2, to read for 25 °C
Max TO weight (1 000 kg) air conditioning OFF = 76.0 + 0.41 × 1 + 0.03 × 11 = 76.7
Retain CONF 1+F for takeoff configuration.
2. First, apply the correction Refer to PER-TOF-TOD-24 EFFECT OF QNH AND BLEEDS.
Max TO weight (1 000 kg) air conditioning OFF.........................................................................77.4
Air conditioning correction.......................................................................................................... – 2.2
Intermediate weight......................................................................................................................75.2
Interpolate takeoff speeds for 75.2 (1 000 kg) in the 10 kt head wind column, V1 = 154 kt, VR =
157 kt, V2 = 160 kt
3. Apply WET correction
For OAT < TVMC (58 °C), ◂W =............................................................................................... – 0.3
Intermediate weight......................................................................................................................74.9
Associated speeds,
V1 = 154 kt – 6 = 148 kt
VR = 157 kt – 0 = 157 kt
V2 = 160 kt – 0 = 160 kt
Apply QNH correction
For OAT < TVMC (54 °C), ◂W = – 0.5 × 15/10 =......................................................................– 0.8
Maximum permissible takeoff weight...........................................................................................74.1
Associated speed,
V1 = 148 kt – 1 × 15/10 = 146 kt
VR = 157 kt – 1 × 15/10 = 156 kt
V2 = 160 kt – 1 × 15/10 = 159 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 those
provided on lines 3 and 4).
