I agree with JT's analysis of the physics and the ultimate authority of the OEM.
Reference the terminology and exam questions, there is no apparent dispute about what 'running load' means so I will disregard that. It seems we have two Airbus definitions which are 'Contact load' and 'Area Load'. There is only one definition in the JAA learning objectives which is related to this and that is:
Area Load or Floor Load
The load (or Mass) distributed over a defined area. Units of measurement used:
SI: N/m2, kg/m2 ; Non-SI: psi, lb/ft2
That definition could match either the Airbus 'Contact load' or the 'Area load', depending on the defined area.
KW, 'static load' is not an LO term, and I do not see, given the imprecise definition above, that you can deduce that 'area load'/'floor load' as defined in the LOs = the Airbus term 'contact load'. Do you have any more info on this?
