Still confused?
Just to clarify in case there is still some confusion:
(1) When dispatching a two-engined transport airplane for a flight with the landing gear locked down -
The takeoff weight may not exceed the weight at which the airplane achieves the 2nd-segment OEI climb gradient of 2.4 % with the gear down.
The landing weight may not exceed the weight at which the airplane achieves the OEI approach climb gradient of 2.1 % with the gear down.
Similar considerations apply for other safety-related performance aspects, such as takeoff distance, final segment climb requirement, obstacle clearance, landing distance, etc.
(2) The title "Landing Climb Limit Weight" should be read as:
LANDING: "Climb-limited weight"
Not as: "Landing climb" Limit Weight
(3) As said before, the climb-limited landing weight is the weight that complies with the OEI approach climb and the AEO landing climb gradient reqirements. The approach climb flap setting is related to the landing flap setting because the stall speed may not exceed 110% of the stall speed in the related landing configuration.
When the landing weight exceeds the climb-limited landing weight in the normal landing configuration, an alternative set of reduced landing and approach flap settings must be used. Again, the the stall speed in the alternative approach-climb configuration may not exceed 110% of the stall speed in the alternative landing configuration. The option to schedule the reduced flap settings exists at dispatch as well as in-flight. The available length of runway must accommodate the increase of required landing distance at the reduced flapsetting.
