couple of comments and questions:
both 747 and f15 seem to be underpowered. or possibly too much drag?
Can't hold a vertical climb in the f15 and can only get to mid altitudes in
the teens with 747
for f15 should be able to do an idle power loop @ 10K feet with an entry
airspeed of around 250 to 300kts
engine egt is given in degrees centigrade and fuel-flow for turbines is
usually given as #/hr (1 gal ~ 6.5 pounds)
Engine data is a little screwy. running jbsim for the c310 no data comes
across and for yasim-747 the zeroeth values are missing.
Not sure i've got this properties thing all figured out yet.
In opengc.cxx
data->n1_turbine[0] = fgGetDouble("/engines/engine[0]/n1");
data->n1_turbine[1] = fgGetDouble("/engines/engine[1]/n1"); // and so
forth
packs the data into the UDP packet
Looks okay?
does each each engine have a throttleor is it a single command for all
four(two)?
