MANUAL CALCULATION OF LANDING DATA
In the absence of ACCULOAD the maximum dispatch Landing Limit Weight
for a specific runway may be determined manually by flight crews using the
following procedures:
1. Determine the maximum Structural Landing Weight for the series aircraft
being flown from the Flight Manual, Chapter 1, Limitations.
2. Calculate the Approach Climb Limit Weight as described below.
3. Calculate the Runway Limit Landing Weight as described below.
4. Select the lesser of these three as the Landing Limit Weight.
Under normal circumstances the landing weight of the B737 is limited by the
maximum structural landing weight. Only in non-normal cases with very high
temperatures, extremely short runways, or with the anti-skid inoperative, will
the maximum dispatch landing weight be below the maximum structural landing
weight.
Approach Climb Limit
If ACCULOAD is not available, determine the Approach Climb Limit in the
following manner:
1. Enter the Approach Climb Limit chart for the appropriate aircraft type and
planned flap setting at the forecast ambient temperature, rounded up to the
next 10 degree increment, and follow that temperature to the appropriate
pressure altitude column. This is the normal Approach Climb Limit
weight.
2. Review the notes below the chart and adjust the weight appropriately to
derive the Approach Climb Limit Weight for the planned non-normal
conditions.
Note: Interpolation is authorized between pressure altitude and temperature
when absolute maximum weight is necessary.
