Guys,
The correct term for this issue is Approach-Climb Gradient, which is calculated by an operator using the manufacturers PEP or SCAP product.
The performance limitation for any approach-climb gradient can be calculated in this way, which is effectively a regulated landing weight, but you won't find the figures published in paper manuals. If your company uses Airbus LPC for example, the performance module may include an approach-climb gradient entry field.
