Obstacle Limit Weight
The Reference Obstacle Limit Weight table provides obstacle limit
weights for reference airport conditions based on obstacle height above the
runway surface and distance from brake release. Enter the adjustment
tables to adjust the reference Obstacle Limit Weight for the effects of OAT,
pressure altitude and wind as indicated. In the case of multiple obstacles,
enter the tables successively with each obstacle and determine the most
limiting weight.
Tire Speed Limit
Tire Speed Limit Weight tables are only provided if they are limiting for
the range of conditions covered in the FCOM Section PD.
Maximum tire speed limited weights are presented for 225 MPH tires. To
determine the tire speed limit weight, enter the table with OAT and airport
pressure altitude. Adjust the tire speed limit weight according to the notes
below the table to account for wind.
Brake Energy Limit VMBE
Brake Energy Limit Weight tables are only provided if they are limiting for
the range of conditions covered in the FCOM Section PD.
The Maximum Brake Energy Speed table provides the Reference VMBE
for a variety of airport pressure altitudes and temperatures. Enter the
Weight Adjusted VMBE table to adjust the Reference VMBE for the actual
brake release gross weight. Correct VMBE for slope and wind. If V1
exceeds VMBE, decrease brake release weight as indicated for each knot
that V1 exceeds VMBE and determine V1, VR, and V2 for the lower brake
release weight.
Enroute
Long Range Cruise Maximum Operating Altitude
These tables provide the maximum operating altitude in the same manner
as the FMC. Maximum altitudes are shown for a given cruise weight and
maneuver capability. Note that this table considers both thrust and buffet
limits, providing the more limiting of the two. Any data that is thrust
limited is denoted by an asterisk and represents only a thrust limited
condition in level flight with 100 ft/min residual rate of climb. Flying
above these altitudes with sustained banks in excess of approximately 15°
may cause the airplane to lose speed and/or altitude. The altitudes shown
in the table are limited to the maximum certified altitude of 41000 ft.
