flightgear/src/FDM/YASim/Airplane.hpp
andy ab381e5c01 Added a property output feature to ControlMap that allows arbitrary binding
and scaling of control values to properties.  Also added a time interpolation
feature that replaces the hacked-in "retract-time" feature for the gear in
a more general way (applicable to flaps, too!).  Incompatibly breaks
the XML syntax; get new files!
