ADVISORY INFORMATION
Slippery Runway Takeoff (22K Derate)
Maximum Reverse Thrust
Weight Adjustment (1000 KG)
V1(MCG) Limit Weight (1000 KG)
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 -30 m/+30 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.
