To facilitate the interpretation of DAVE-ML packages, the following conventions are proposed. Failure to follow any of these should be noted prominently in the data files and any cover documentation.
It is recommended that all force and moments be considered to act around a defined reference point, given in aircraft coordinates. It is further recommended that all subsystem models (aerodynamic, propulsive, alighting gear) provide total forces & moments about this reference point and leave the transfer of moments to the center of mass to the equations of motion.
