Hello!

I wanted to use the Surface Launch Program from IMFD for my launch timing today. I have loaded the XR2 Scn "1 - Ready for takeoff to ISS".
But the Surface Launch Program does not show any data from the Course Program.
What I did:

Left IMFD: MNU -> Course -> Target Intercept -> Target: ISS -> TEj: 0

Right IMFD: MNU -> OpMode: 0 -> Surface Launch

So the course data should be used by the right IMFD for the Surface Launch Program, right?

IMFD has some kind of a "share" function.
You need to "share" the left MFD to the right MFD in your case.
So launch-data can be "Injected" via "MFD-share-function".

The "share" function is somewhere on the main-page of IMFD.
So you need to set "share 0" on the right MFD. So right MFD "queries" left MFD.

But however, I am pretty sure, that there are even much more complicated was to go to the ISS.
Why not using the simple efficient way ?
You could use Launch-MFD and on top...if using the XR-crafts...use scramMFD to perform a semi-auto SCRAM ascent.
Just disable the pitch program (PTC button) in Launch-MFD and let scramMFD handle the pitch.
While launch-MFD still manages the heading.

The rest is standard stuff...just watch your APA and do the circulation burn at apoapsis (i.e. BurnMFD is quit helpfull for this last task).

Hello Turtle,

yes, that's what I meant by "OpMode:0", I share the date from left (0) with right. But there is no data available.
Sure, I know there is another way to launch to ISS, that was something like my minimal example. It should work here too if I want to use it elsewhere, shouldn't it?
Launch MFD is another question ;-)

I think it is about TEj being zero, since you are not in an orbit, but on the ground. Just use Surface Launch.

Barbarian's method : look at Map MFD. Wait untill ISS passes above your position. Launch with the same Inc. Then standard procedure for Rendez-vous (align plane / sync Orbit). Done. :p

More seriously : i don't use IMFD for ISS missions, but i think "target intercept" isn't the good program. I use Target Intercept when i'm out of earth's sphere of influence, as to make corrections or plane change for interplanetary travels. As you and the ISS orbit the same body (earth), a tangential transfer could be better. But i don't know if the datas are shared between left and right MFDs for this program. I'm at work right now, and they don't allow me to play Orbiter ! ;)
A small but good advice i can give to you is don't forget to "refresh" MFD on the right when ISS is 180° from your position on the last orbit before launch. You'll get a more accurate solution. It's to be done for interplanetary flights too. I hope it helps, have a nice docking !
