1. Enter Weight Adjustment table with reported braking action and 20K derate dry field/obstacle limit
weight to obtain slippery runway weight adjustment.
2. Adjust "Good" field length available by -90ft/+90ft for every 5°C above/below 4°C
Adjust "Medium" field length available by -90ft/+90ft for every 5°C above/below 4°C
Adjust "Poor" field length available by -117ft/+117ft 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 slippery runway limited weight is lesser of weights from 1 and 3.
