Introduction
This chapter contains self dispatch performance data intended primarily
for use by flight crews in the event that information cannot be obtained
from the airline dispatch office. The data provided is for a single takeoff
flap at max takeoff thrust. The range of conditions covered is limited to
those normally encountered in airline operation. 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.
Takeoff
The maximum allowable takeoff weight will be the least of the Field,
Climb, and Obstacle Limit Weights as determined from the following
tables. Tire and Brake Energy Limits are not shown as they are not
limiting for the range of conditions shown in this chapter.
Field Limit Weight - Slope and Wind Corrections
These tables for dry and wet runways provide corrections to the field
length available for the effects of runway slope and wind component along
the runway. Enter the Slope Correction table with the available field
length and runway slope to determine the slope corrected field length.
Now enter the Wind Correction table with slope corrected field length and
wind component to determine the slope and wind corrected field length.
Field and Climb Limit Weight
Tables are presented for selected airport pressure altitudes and runway
condition and show both Field and Climb Limit Weights. Enter the
appropriate table for pressure altitude and runway condition with “Slope
and Wind Corrected Field Length” determined above and airport OAT to
obtain Field Limit Weight. Also read Climb Limit Weight for the same
OAT. Intermediate altitudes may be interpolated or use next higher
altitude.
When finding a maximum weight for a wet runway, the dry runway limit
weight must also be determined and the lower of the two weights used.
Obstacle Limit Weight
This table provides obstacle limit weights for reference airport conditions
based on obstacle height above the runway surface and distance from brake
release. Enter the correction tables to correct the reference Obstacle Limit
