1. Enter Weight Adjustment table with slush/standing water depth and 18.5K derate dry field/obstacle
limit weight to obtain slush/standing water weight adjustment.
2. Adjust field length available by -99ft/+99ft for every 5°C above/below 4°C
3. Find V1(MCG) limit weight for temperature adjusted field length and pressure altitude.
4. Max allowable slush/standing water limited weight is lesser of weights from 1 and 3.

1. Obtain V1, VR and V2 for the actual weight.
2. If V1(MCG) limited, set V1 = V1(MCG). If not V1(MCG) limited, enter V1 Adjustment Table with the
actual weight to obtain V1 speed adjustment. If adjusted V1 is less than V1(MCG), set V1 = V1(MCG).
