Field and Climb Limit Weight
Tables are presented for selected airport pressure altitudes and runway conditions 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
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
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
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.
Long Range Cruise Trip Fuel and Time
Long Range Cruise Trip Fuel and Time tables are provided to determine
trip time and fuel required to destination. To determine trip fuel and time for a constant altitude cruise, first enter the Ground to Air Miles Conversion table to convert ground distance and enroute wind to an equivalent still air distance for use with the Reference Fuel and Time tables.  Next, enter the Reference Fuel and Time table with air distance from the Ground to Air Miles Conversion table and the desired altitude and read Reference Fuel and Time Required.  Lastly, enter the Fuel

Required Adjustment table with the Reference Fuel and the planned landing weight to obtain the adjustment to the fuel required at the planned landing weight.
Long Range Cruise Step Climb Trip Fuel and Time
The Long Range Cruise Step Climb Trip Fuel and Time tables are provided to determine trip time and fuel required to destination when flying a step climb profile. Step climb profiles are based on 4000 ft step climbs to keep the flight within 2000 ft of the optimum altitude for the current cruise weight. To determine trip fuel and time, enter the Ground to Air Miles Conversion table and determine air distance as discussed above.  Then enter the Trip Fuel and Time Required table with air distance and planned landing weight to read trip fuel.  Continue across the table to read trip time.
Short Trip Fuel and Time
These tables are provided to determine trip fuel and time for short distances or alternates. Obtain air distance from the table using the ground distance and wind component to the alternate. Enter the Trip Fuel and Time Required table with air distance and read trip fuel required for the expected landing weight, together with time to alternate at right. For distances greater than shown or other altitudes, use the Long Range Cruise Trip Fuel and Time tables.
Holding Planning
This table provides total fuel flow information necessary for planning flaps up holding and reserve fuel requirements. Data is based on the FMC holding speed schedule which is the higher of the maximum endurance  and flaps up maneuver speeds.  As noted, the fuel flow is based on flight in a racetrack holding pattern.  For holding in straight and level flight, reduce table values by 5%.
