Introduction
This chapter contains information to supplement performance data from
the Flight Management Computer (FMC). In addition, sufficient inflight
data is provided to complete a flight with the FMC inoperative. In the event
of conflict between data presented in this chapter and that contained in the
Approved Flight Manual, the Flight Manual shall always take precedence.
General
Takeoff Speeds
The speeds presented in the Takeoff Speeds table, as well as FMC
computed takeoff speeds, can be used for all performance conditions
provided adjustments are made to V1 for clearway, stopway, brake
deactivation, improved climb, contaminated runway situations, brake
energy limits or obstacle clearance with unbalanced V1. These speeds may
be used for weights less than or equal to the performance limited weight.
Normal takeoff speeds, V1, VR, and V2, with anti-skid on, are read from
the table by entering with takeoff flap setting, brake release weight, and
appropriate column. The appropriate column is obtained by entering the
Column Reference chart with the airport pressure altitude and the actual
temperature. If an Altitude Adjustment chart is provided, adjust the takeoff
speeds appropriately. Slope and wind adjustments to V1 are obtained by
entering the Slope and Wind V1 Adjustment table.
V1(MCG)
Regulations prohibit scheduling takeoff with a V1 less than minimum V1
for control on the ground, V1(MCG). Therefore compare the adjusted V1
to the V1(MCG). To find V1(MCG) enter the V1(MCG) table with the
airport pressure altitude and actual OAT. If applicable, add the
adjustments shown below the table. If the adjusted V1 is less than
V1(MCG), set V1 equal to V1(MCG). If VR is less than V1(MCG), set VR
equal to V1(MCG), and determine a new V2 by adding the difference
between the normal VR and V1(MCG) to the normal V2.
If it is necessary to increase V1 to V1(MCG), then provided the actual field
length exceeds the minimum field length of 4500 ft no takeoff weight
adjustment is necessary.

Clearway and Stopway V1 Adjustments
Takeoff speed corrections are to be applied to V1 speed when using takeoff
weights based on the use of clearway and stopway.
Adjust V1 speed by the amount shown in the appropriate column. The
adjusted V1 speed must not exceed VR. If the adjusted V1 speed is greater
