// Initial revision

+// Revision 1.5 2001/03/24 05:03:12 curt
+// SG-ified logstream.
+//
+// Revision 1.4 2000/10/23 22:34:54 curt
+// I tested:
+// LaRCsim c172 on-ground and in-air starts, reset: all work
+// UIUC Cessna172 on-ground and in-air starts work as expected, reset
+// results in an aircraft that is upside down but does not crash FG. I
+// don't know what it was like before, so it may well be no change.
+// JSBSim c172 and X15 in-air starts work fine, resets now work (and are
+// trimmed), on-ground starts do not -- the c172 ends up on its back. I
+// suspect this is no worse than before.
+//
+// I did not test:
+// Balloon (the weather code returns nan's for the atmosphere data --this
+// is in the weather module and apparently is a linux only bug)
+// ADA (don't know how)
+// MagicCarpet (needs work yet)
+// External (don't know how)
+//
+// known to be broken:
+// LaRCsim c172 on-ground starts with a negative terrain altitude (this
+// happens at KPAO when the scenery is not present). The FDM inits to
+// about 50 feet AGL and the model falls to the ground. It does stay
+// upright, however, and seems to be fine once it settles out, FWIW.
+//
+// To do:
+// --implement set_Model on the bus
+// --bring Christian's weather data into JSBSim
+// -- add default method to bus for updating things like the sin and cos of
+// latitude (for Balloon, MagicCarpet)
+// -- lots of cleanup
+//
+// The files:
+// src/FDM/flight.cxx
+// src/FDM/flight.hxx
+// -- all data members now declared protected instead of private.
+// -- eliminated all but a small set of 'setters', no change to getters.
+// -- that small set is declared virtual, the default implementation
+// provided preserves the old behavior
+// -- all of the vector data members are now initialized.
+// -- added busdump() method -- SG_LOG's all the bus data when called,
+// useful for diagnostics.
+//
+// src/FDM/ADA.cxx
+// -- bus data members now directly assigned to
+//
+// src/FDM/Balloon.cxx
+// -- bus data members now directly assigned to
+// -- changed V_equiv_kts to V_calibrated_kts
+//
+// src/FDM/JSBSim.cxx
+// src/FDM/JSBSim.hxx
+// -- bus data members now directly assigned to
+// -- implemented the FGInterface virtual setters with JSBSim specific
+// logic
+// -- changed the static FDMExec to a dynamic fdmex (needed so that the
+// JSBSim object can be deleted when a model change is called for)
+// -- implemented constructor and destructor, moved some of the logic
+// formerly in init() to constructor
+// -- added logic to bring up FGEngInterface objects and set the RPM and
+// throttle values.
+//
+// src/FDM/LaRCsim.cxx
+// src/FDM/LaRCsim.hxx
+// -- bus data members now directly assigned to
+// -- implemented the FGInterface virtual setters with LaRCsim specific
+// logic, uses LaRCsimIC
+// -- implemented constructor and destructor, moved some of the logic
+// formerly in init() to constructor
+// -- moved default inertias to here from fg_init.cxx
+// -- eliminated the climb rate calculation. The equivalent, climb_rate =
+// -1*vdown, is now in copy_from_LaRCsim().
+//
+// src/FDM/LaRCsimIC.cxx
+// src/FDM/LaRCsimIC.hxx
+// -- similar to FGInitialCondition, this class has all the logic needed to
+// turn data like Vc and Mach into the more fundamental quantities LaRCsim
+// needs to initialize.
+// -- put it in src/FDM since it is a class
+//
+// src/FDM/MagicCarpet.cxx
+// -- bus data members now directly assigned to
+//
+// src/FDM/Makefile.am
+// -- adds LaRCsimIC.hxx and cxx
+//
+// src/FDM/JSBSim/FGAtmosphere.h
+// src/FDM/JSBSim/FGDefs.h
+// src/FDM/JSBSim/FGInitialCondition.cpp
+// src/FDM/JSBSim/FGInitialCondition.h
+// src/FDM/JSBSim/JSBSim.cpp
+// -- changes to accomodate the new bus
+//
+// src/FDM/LaRCsim/atmos_62.h
+// src/FDM/LaRCsim/ls_geodesy.h
+// -- surrounded prototypes with #ifdef __cplusplus ... #endif , functions
+// here are needed in LaRCsimIC

+// src/FDM/LaRCsim/ls_geodesy.h
+// src/FDM/LaRCsim/ls_step.c
+// src/FDM/UIUCModel/uiuc_betaprobe.cpp
+// -- changed PI to LS_PI, eliminates preprocessor naming conflict with
+// weather module
+//
+// src/FDM/LaRCsim/ls_interface.c
+// src/FDM/LaRCsim/ls_interface.h
+// -- added function ls_set_model_dt()
+//
+// src/Main/bfi.cxx
+// -- eliminated calls that set the NED speeds to body components. They
+// are no longer needed and confuse the new bus.
+//
+// src/Main/fg_init.cxx
+// -- eliminated calls that just brought the bus data up-to-date (e.g.
+// set_sin_cos_latitude). or set default values. The bus now handles the
+// defaults and updates itself when the setters are called (for LaRCsim and
+// JSBSim). A default method for doing this needs to be added to the bus.
+// -- added fgVelocityInit() to set the speed the user asked for. Both
+// JSBSim and LaRCsim can now be initialized using any of:
+// vc,mach, NED components, UVW components.
+//
+// src/Main/main.cxx
+// --eliminated call to fgFDMSetGroundElevation, this data is now 'pulled'
+// onto the bus every update()
+//
+// src/Main/options.cxx
+// src/Main/options.hxx
+// -- added enum to keep track of the speed requested by the user
+// -- eliminated calls to set NED velocity properties to body speeds, they
+// are no longer needed.
+// -- added options for the NED components.
+//
+// src/Network/garmin.cxx
+// src/Network/nmea.cxx
+// --eliminated calls that just brought the bus data up-to-date (e.g.
+// set_sin_cos_latitude). The bus now updates itself when the setters are
+// called (for LaRCsim and JSBSim). A default method for doing this needs
+// to be added to the bus.
+// -- changed set_V_equiv_kts to set_V_calibrated_kts. set_V_equiv_kts no
+// longer exists ( get_V_equiv_kts still does, though)
+//
+// src/WeatherCM/FGLocalWeatherDatabase.cpp
+// -- commented out the code to put the weather data on the bus, a
+// different scheme for this is needed.

+// MacOS build updates.
+//
+// Revision 1.2 2000/04/10 18:09:41 curt
+// David Megginson made a few (mostly minor) mods to the LaRCsim files, and
+// it's now possible to choose the LaRCsim model at runtime, as in
+//
+// fgfs --aircraft=c172
+//
+// or
+//
+// fgfs --aircraft=uiuc --aircraft-dir=Aircraft-uiuc/Boeing747
+//
+// I did this so that I could play with the UIUC stuff without losing
+// Tony's C172 with its flaps, etc. I did my best to respect the design
+// of the LaRCsim code by staying in C, making only minimal changes, and
+// not introducing any dependencies on the rest of FlightGear. The
+// modified files are attached.
