Set *geodetic* latitude position from python for initial condition (not via xml)

[clolsonus]

Hey everyone,

I have been messing around on the side a bit with jsbsim and the python wrappers. I can start up anywhere I like using an IC.xml file, but I'd like to explore setting "ic/xyz" properties programmatically. From what I can see, the "ic/xyz" properties expect geocentric coordinates, and FGInitialCondition or FGLocation is not exposed to the python api. Is there a quick way to do this or have gone down a rabbit hole no one ever anticipated?

Thanks!

Curt. (of FlightGear infamy) :-)

Looks to me like both geocentric and geodetic options are available?

jsbsim/src/initialization/FGInitialCondition.cpp

Lines 1488 to 1490 in b9bfc23

	PropertyManager->Tie("ic/lat-gc-deg", this,
	&FGInitialCondition::GetLatitudeDegIC,
	&FGInitialCondition::SetLatitudeDegIC);

jsbsim/src/initialization/FGInitialCondition.cpp

Lines 1584 to 1586 in b9bfc23

	PropertyManager->Tie("ic/lat-geod-deg", this,
	&FGInitialCondition::GetGeodLatitudeDegIC,
	&FGInitialCondition::SetGeodLatitudeDegIC);

Ok, maybe it was just missed in the docs then ... I will give it a try. Thanks for the quick reply!

The source code is the definitive document 😉
