ADVISORY INFORMATION
TO2 Wet Snow Takeoff
20% Thrust Reduction
Maximum Reverse Thrust
Table 1 of 3: Weight Adjustment (1000 KG)
Table 2 of 3: V1(MCG) Limit Weight (1000 KG)
1. Enter Table 1 with wet snow depth and TO2 dry field/obstacle limit weight to obtain wet snow
weight adjustment.
2. Adjust field length available by -30 m/+30 m for every 10°C above/below 0°C.
3. Find V1(MCG) limit weight for adjusted field length and pressure altitude (Table 2).
4. Max allowable wet snow limited weight is lesser of weights from Table 1 and Table 2.
Table 3 of 3: V1 Adjustment (KIAS)
1. Obtain V1, VR and V2 for the actual weight using the TO2 Dry Runway Takeoff Speeds table.
2. If V1(MCG) limited, set V1 = V1(MCG). If not V1(MCG) limited, enter Table 3 with the actual
weight to obtain V1 speed adjustment. If adjusted V1 is less than V1(MCG), set V1 = V1(MCG).
V1 not to exceed VR.
