The attached patch adds "Hide yoke" to the c172p menu, adjusts the gear spring forces and damping to cause a more tail low attitude sitting on the ground, optimizes vertices and surfaces in c172p.ac, as well as cleaning up the tabs and indents in several xml files.
This is a patch to the c172p fdm to add pointmasses for all four
occupant positions and baggage. The X locations were taken from the
c172 type certificate 3A12 dated September 15, 1998. As the new
pointmasses have a weight of 0 they will not affect the current model,
however we are extending the FlightGear weight and balance dialog for
JSBSim and the pointmasses have to be defined.
Make the plane much sloppier at high alpha and/or with the flaps
extended. In slow flight, there's much more lateral instability now,
and adverse yaw is more obvious at the start of a turn using only
ailerons.
