1. Enter Weight Adjustment table with reported braking action and 22K Derate dry field/obstacle
limit weight to obtain slippery runway weight adjustment.
2. Adjust “Good” field length available by -20 m/+20 m for every 5°C above/below 4°C.
Adjust “Medium” field length available by -20 m/+20 m for every 5°C above/below 4°C.
Adjust “Poor” field length available by -40 m/+40 m for every 5°C above/below 4°C.
3. Find V1(MCG) limit weight for adjusted field length and pressure altitude.
4. Max allowable slippery runway limited weight is lesser of weights from 1 and 3.
