The problem here appears to be one of terminology.
If you go to page 221 of the Airbus document you will find a third limit called the "Contact Load Limitation".
a) Contact load limitation
• Definition: The contact load limitation is the maximum load acceptable in direct contact with the aircraft floor per surface unit. This limitation is used to prevent the load in direct contact with the floor from exceeding the capability of the horizontal floor panels (metal sheet, honey comb sandwich panels).
Note:
The Contact Load Limitation is called “Local load” limitation in the Airbus Weight and Balance manuals.
• Unit: kg/m2 or lb/ft2
S = Contact Area
W = Contact Load
Contact Load = Weight of the piece / Contact Area
The contact area is the surface in direct contact with the floor.
The JAR/EASA ATPL Mass & Balance syllabus includes only two limitations. These are:
1. Static Load Limit. This is the equivalent of the Contact load Limit in the Airbus document.
2. Running Load Limit. This is as described as the Running Linear Load Limit in the Airbus Document.
